GMRS: What can it Really Do?

In this episode, Caleb Nelson (K4CDN | WRBR237) breaks down what GMRS can really do—and what it can't.

You'll learn how far GMRS actually reaches, why antenna height beats transmitter power every time, and what equipment upgrades make the biggest difference for families building real communication plans.

We'll also cover license coverage, the truth about 50 watts, repeater basics, and why investing in a better antenna might triple your range overnight.

00:00:11
Welcome into the PrepCom's podcast.

00:00:14
I'm your host Caleb Nelson, K4CDN, WRBR237 in

00:00:19
the squeaky chair today and we're going to

00:00:22
the GMRS series episode number two.

00:00:25
So we've recently finished up a little small

00:00:28
series about the FRS radio before that MURS

00:00:31
radio.

00:00:32
If you've missed those, go check them out.

00:00:34
Matter of fact, go back to the beginning

00:00:35
and come all the way through with us.

00:00:38
A lot of great information what to listen

00:00:40
to, how to listen to, why you should

00:00:42
be listening in case of an emergency or

00:00:44
any prepper dystopian nightmare you may have.

00:00:48
And we're here to help you figure out

00:00:50
your communications for those scenarios you may be

00:00:52
prepping for.

00:00:53
Even if you're not preparing for anything, we

00:00:57
can still help you learn through how to

00:01:00
talk to folks when maybe the phones go

00:01:02
down.

00:01:02
Maybe the AWS goes down again and this

00:01:05
time it affects a sailor carrier.

00:01:08
Wow, yeah, what would you do?

00:01:10
That's what we're talking about here.

00:01:11
So this is episode number two of the

00:01:13
GMRS series.

00:01:14
Again, I'm Caleb.

00:01:14
Thank you for being here with us and

00:01:16
genuinely appreciate all the conversation that we have

00:01:19
in regards to these episodes.

00:01:22
Yeah, if you've missed the first episode, we

00:01:24
just began talking about GMRS radio, the general

00:01:27
mobile radio service.

00:01:30
And it's free for people to use in

00:01:31
the US as long as you pay a

00:01:33
$35 licensing fee and your whole household can

00:01:37
use it.

00:01:37
So we've talked about that.

00:01:39
We're going to talk about that more in

00:01:41
depth this time.

00:01:42
And why this is really the best starting

00:01:46
point for families who want a real working

00:01:49
communications plan, who want a little bit more

00:01:52
than the bubble pack radios that their kids

00:01:54
got for Christmas about six years ago.

00:01:57
And they just found them as they were

00:01:59
cleaning out for the for the art sale.

00:02:02
So we're actually going to get into the

00:02:03
what does GMRS do when the rubber meets

00:02:06
the road or when the cell towers stop

00:02:09
working and you need an alternative, right?

00:02:10
So we're talking range, power and reality.

00:02:13
We're talking marketing versus miles and no offense.

00:02:18
No offense guys, but we're not talking YouTube

00:02:20
hype here.

00:02:21
I'm not trying to sell you the newest

00:02:23
latest greatest battle thing for $17.

00:02:26
I just want to help you understand what

00:02:28
these radios in this service can and cannot

00:02:31
do for your family.

00:02:33
Before we continue, this show is sponsored by

00:02:36
the family connect system is a system that

00:02:39
I've developed to help you and your family

00:02:40
stay connected.

00:02:41
If and when these cell networks go down,

00:02:43
if and when AWS collapses, again, maybe stuff

00:02:46
just maybe it's a bad day.

00:02:48
Maybe it's a tornado.

00:02:50
And you don't know what to do what

00:02:51
what you would do.

00:02:52
Family connect system will help you with that.

00:02:55
We'll talk about it more in a few

00:02:55
minutes.

00:02:56
But first, this is one of the questions

00:02:59
I got and and folks wanted some more

00:03:02
clarification on after the first episode here in

00:03:05
the series.

00:03:06
If I buy this license, really who can

00:03:08
talk underneath me or underneath my license.

00:03:11
Well, we'll go back and we look at

00:03:13
the FCC rulebook who is in charge of

00:03:15
the spectrum in the US part 95 subparty

00:03:18
and you'll find 955. You can look

00:03:22
it up and I think there's a link

00:03:24
in the show notes or in the blog

00:03:25
post here.

00:03:26
It says that GMRS license covers you and

00:03:29
your immediate family members.

00:03:31
Now, you know, I know some people's trees

00:03:34
are different.

00:03:35
Right.

00:03:36
So like your tree may come down a

00:03:38
couple of branches and split and just start

00:03:40
a whole new tree or you may have

00:03:41
a tree that's grafted in.

00:03:43
And now it's got a couple of different

00:03:45
kinds of fruit on it.

00:03:46
I don't know.

00:03:46
But but that's my funny way of saying

00:03:49
spouse, kids, parents, grandparents, brothers, sisters and in

00:03:53
-laws.

00:03:54
Brothers of your dad, maybe is an uncle.

00:03:57
I mean, again, it's a great area.

00:04:00
Here's here's an easy way to look at

00:04:02
it.

00:04:02
If they're in your family tree, they can

00:04:04
pick up and talk and use your call

00:04:07
sign.

00:04:08
They don't have to pay any fees.

00:04:09
They don't have to take any test or

00:04:10
anything.

00:04:11
They can do that.

00:04:12
The catch there is a catch.

00:04:14
You, if your name is on the license,

00:04:16
if you're the license holder of that call

00:04:19
sign, like I am the license holder of

00:04:23
WRBR 237.

00:04:25
That's my GMRS of associated call sign that

00:04:29
the FCC gave me when I applied and

00:04:33
paid the fees.

00:04:34
Okay.

00:04:35
I'm the license holder.

00:04:37
I am responsible for everything that happens underneath

00:04:41
that call sign.

00:04:42
So my kid picks up the radio and

00:04:44
gets on one of the local GMRS repeaters

00:04:46
and is being foolish and saying things that

00:04:49
are dumb and, you know, calls in interference

00:04:52
or whatever.

00:04:53
And he's using my call sign and I'm

00:04:56
out in Reno, Nevada on vacation and he's

00:04:58
here in South Carolina.

00:05:00
It doesn't matter because he's still doing it

00:05:04
with my call sign, which makes me responsible.

00:05:07
I am the responsible party for everything that

00:05:10
happens if someone's using that call sign.

00:05:12
All right.

00:05:14
That's just how it is.

00:05:16
So you have to be cautious in who

00:05:19
you share.

00:05:20
You have to be cautious in who you

00:05:22
share your license with.

00:05:24
Now, the license is a piece of paper

00:05:26
that you can print and the call sign

00:05:29
is what's on the license.

00:05:31
So it's not like you have to hand

00:05:32
your brother-in-law a paper copy of

00:05:35
it, but he does need to be aware

00:05:37
of what the call sign is because just

00:05:41
like we talked last week, every 15 minutes

00:05:44
and at the beginning and end of the

00:05:46
conversation on the radio, you have to identify

00:05:49
yourself with that call sign.

00:05:50
The easiest way to do this is a

00:05:52
silver Sharpie marker.

00:05:54
And you take the silver Sharpie and you

00:05:56
write on because most radio chassis are black.

00:05:59
You write with the silver Sharpie on the

00:06:01
radio the call sign.

00:06:03
If you've got a one of those printers,

00:06:05
the little label makers, it's even easier.

00:06:08
Type it in, print it off, stick it

00:06:09
to the radio.

00:06:10
Ta-da.

00:06:11
So here's the easiest way to say it

00:06:13
going back to whom you should allow to

00:06:15
use it.

00:06:16
Okay?

00:06:17
The rules are written on purpose.

00:06:20
You have to trust the people you're allowing

00:06:23
to use the radio under you, under your

00:06:26
call sign.

00:06:27
GMRS is for, you know, we're talking families

00:06:30
here, so they're expecting you to be familiar

00:06:33
with the people that you're allowing to use

00:06:35
your call sign and trust them.

00:06:37
And I would say, here's how it's at

00:06:39
in South Carolina.

00:06:39
If you wouldn't hand that person, the keys

00:06:42
to your pickup truck, don't let them use

00:06:44
your call sign.

00:06:45
There you go.

00:06:46
That's that's an easy way to do it.

00:06:48
If you don't trust them with the keys

00:06:49
to your boat, don't trust them with your

00:06:51
call sign.

00:06:52
Okay.

00:06:53
All right, so we've heard in the last

00:06:56
show and you hear online and the marketing

00:06:59
and whatever, you know, let's talk about wattage.

00:07:01
We'll talk about more power, more power, and

00:07:03
you'll see some of the and that is

00:07:08
the legal maximum output power for mobile based

00:07:12
and repeater transmitters under 95. I'm sorry,

00:07:16
1767A1.

00:07:19
But here's the thing.

00:07:21
And we've talked about this before.

00:07:23
We'll talk about it numerous times until we

00:07:25
finish with this program.

00:07:26
More power doesn't always mean more distance.

00:07:29
Go all the way back to the CB

00:07:31
radio shows where I was talking about as

00:07:33
a kid illegal power amplifiers.

00:07:37
You haven't plugged into a junky antenna and

00:07:41
you're like, I don't know why they can't

00:07:42
hear me.

00:07:43
This is a Texas star 250, you know,

00:07:45
but you had this this antenna mounted to

00:07:48
your bumper.

00:07:49
There was a fiberglass whip that was only

00:07:51
about four feet tall because you thought it

00:07:52
looked cool, but it wouldn't perform worth anything

00:07:54
because there was no ground plane.

00:07:56
And I'm not trying to talk above your

00:07:57
head.

00:07:57
I'm just saying more power doesn't always mean

00:07:59
more distance.

00:08:00
Okay.

00:08:01
That's a great example from back in my

00:08:02
ignorant days of CB radio operating not that

00:08:05
CB guys are ignorant I was because I

00:08:07
didn't understand the antenna makes the difference.

00:08:10
Okay.

00:08:11
So you can take a five watt walkie

00:08:13
talkie with a roof mounted antenna on your

00:08:16
home and it will outperform a 50 watt

00:08:20
base station or a mobile radio like in

00:08:25
your car connected to a junky antenna.

00:08:28
And again, especially in regards to GMRS, it's

00:08:33
because how you get out there, how your

00:08:36
signal is sent and received with these type

00:08:39
of frequencies is line of sight.

00:08:42
So elevation, getting above things, right?

00:08:47
Having more forward gain on an antenna, it's

00:08:50
great that people can hear you, but can

00:08:52
you hear them?

00:08:52
I mean, so you have to you have

00:08:54
to take all these things into consideration because

00:08:56
radio radio waves, they travel straight, right?

00:09:00
So the higher you get there and it

00:09:07
can be seen.

00:09:08
So you want to be able to have

00:09:11
a good antenna, you want to be able

00:09:13
to put in place an antenna at the

00:09:16
highest point that you can.

00:09:18
And let's just take your car, for instance,

00:09:21
you're inside your car with a walkie talkie.

00:09:23
So you've got a little radio with a

00:09:25
little antenna surrounded by a fair day cage.

00:09:28
And you're like, I don't know why anyone

00:09:29
can't hear me.

00:09:31
Get a magnet antenna, put it on the

00:09:33
roof of your car, and it's going to

00:09:34
change your life because the signal's able to

00:09:36
get out.

00:09:37
It's elevated, it's tuned, and it's not inside

00:09:41
a fair day cage.

00:09:44
Think about it like a flashlight.

00:09:45
So you're out in the field, you know,

00:09:47
you just imagine it's dark and you're out

00:09:49
out there in the corn, like the children

00:09:53
of the corn movie, right?

00:09:54
And you can only kind of see as

00:09:56
far as your light will go and won't

00:09:58
go real far because it's you've got a

00:10:00
lot of stuff in the way.

00:10:02
You've got like corn stalks and weeds and

00:10:05
you're down at that level.

00:10:07
But just imagine if you were to get

00:10:09
up on top of the barn or maybe

00:10:11
the silo and you were able to take

00:10:13
the same flashlight, you could see a lot

00:10:15
further.

00:10:16
Yeah, I mean, you can see a lot

00:10:18
further because you have that space where there's

00:10:24
nothing between you, your line of sight.

00:10:26
So you're you're increasing your capacity, you're higher,

00:10:29
you're above the things.

00:10:31
And it works the same way with your

00:10:34
radio.

00:10:35
That's why you that's why you see people

00:10:38
when their phones aren't working, they're holding them

00:10:40
up over their heads, you know, trying to

00:10:42
find a better signal or something.

00:10:44
It happens all the time on my farm

00:10:45
because we only have one carrier that really

00:10:47
works down here, which is kind of fun.

00:10:49
But anyway, stuff gets in the way of

00:10:51
radio signals.

00:10:53
So, you know, the power is going to

00:10:54
help get you through those things.

00:10:56
But at some point, the power is only

00:10:59
going to do as much as it can.

00:11:01
And then you're going to really need you're

00:11:05
really going to need that elevation.

00:11:07
You're going to need that extra antenna that

00:11:10
above the roof of the car above the

00:11:13
roof of the house.

00:11:14
So you can have 50 watts.

00:11:17
Okay, 50 watts up to 50 watts on

00:11:20
GMRS makes a big difference.

00:11:21
I mean, it really makes a big difference.

00:11:24
Unless you don't have a way to control

00:11:28
that or a way to to amplify that,

00:11:31
which is the wrong word to use, maybe

00:11:33
send it in the correct direction or have

00:11:35
it above the distractions or the the displacement.

00:11:39
The stuff that's in the way of the

00:11:41
signal.

00:11:42
So, height above ground level, just like going

00:11:45
back to MURS, because we can have these

00:11:48
external antennas, we can have this height above

00:11:50
ground level.

00:11:51
We can have these bigger numbers of output

00:11:52
wattage.

00:11:53
You got to have it.

00:11:54
So, if you're thinking about doing GMRS and

00:11:57
the cool thing about GMRS is everybody gets

00:12:00
hung up on walkie talkies in regards to

00:12:02
every radio service, except maybe CB radio, everybody,

00:12:06
all they want is walkie talkies.

00:12:08
And it's because we're used to having a

00:12:10
phone in our pocket and we see them

00:12:11
use them in the movies and they're talking

00:12:13
all over the world and whatever.

00:12:15
Oh, man, I have so many walkie talkies,

00:12:19
this embarrassing.

00:12:20
I honestly don't know how many I own.

00:12:23
I really don't know.

00:12:25
And outside of running fire calls with the

00:12:27
local fire department squeaky chair without, if I

00:12:31
didn't do anything with the fire department, I

00:12:33
would almost never use a walkie talkie or

00:12:36
in the hand radio hobby, we call it

00:12:38
a handy talkie, an HT or a WT.

00:12:41
How's that?

00:12:43
So, don't get hung up on the walkie

00:12:47
talkie thing.

00:12:48
You can buy these radios for GMRS. They're

00:12:50
micro.

00:12:51
I mean, they're so tiny.

00:12:53
You can install it in your car.

00:12:56
They're small enough to go between your front

00:12:58
seat and your console and you don't even

00:13:01
have to have a mounting bracket.

00:13:02
You just kind of shove it in and

00:13:04
it's going to hold it there.

00:13:05
They're so, they're so tiny.

00:13:07
They'll go in a little spots like that

00:13:08
and they'll give you so much more power

00:13:11
than your handy talkie, walkie talkie.

00:13:15
And they also connect to an external antenna.

00:13:17
And oh, man, I'm telling you, just don't

00:13:20
get hung up on the walkie talkies, especially

00:13:22
if you want to talk to your friends

00:13:23
while you're driving to work or maybe you're

00:13:26
traveling with your family.

00:13:28
The external antenna on your car is going

00:13:30
to make a huge difference.

00:13:31
Now, last time, again, we talked and we

00:13:33
even mentioned this in the FRS series, but

00:13:36
we talked about the marketing on the boxes.

00:13:39
I'm sorry about my chair.

00:13:41
It just makes too much noise.

00:13:43
I sat down in the wrong one as

00:13:44
I started recording.

00:13:46
So on the marketing box, the boxes are

00:13:49
the claims on the internet, the reviews.

00:13:53
99% of the people are going to

00:13:54
be straight with you.

00:13:55
They're not going to talk as far as

00:13:57
they claim on the boxes.

00:13:58
They're just not going to do it.

00:14:00
And it's marketing.

00:14:02
It's not reality.

00:14:03
So can you talk 36 miles on GMRS?

00:14:07
You can probably talk a lot further than

00:14:09
that if the conditions were correct.

00:14:11
If you were, you know, in the middle

00:14:12
of space with nothing between you and the

00:14:14
other station.

00:14:16
Yeah, you could do that.

00:14:18
Is it realistic most for most people?

00:14:21
No, it's not.

00:14:21
It's not unless you live out, you know,

00:14:23
in the high planes or something.

00:14:25
And a lot of people live in a

00:14:27
neighborhood.

00:14:27
A lot of people live in the city,

00:14:28
even like us out here in the rural

00:14:30
area, our VHF radios, which would be like

00:14:34
the MERS.

00:14:35
We've talked about work better than the GMRS

00:14:37
radios, just because the signal happens to interact

00:14:43
with its surroundings differently.

00:14:45
So if you live in town with houses

00:14:46
and trees, you could probably expect maybe a

00:14:49
mile or two with GMRS. And that depends

00:14:53
on how many houses and trees you have

00:14:55
between you and the other station.

00:14:57
Okay, it also depends on what type of

00:14:59
radio in antenna are you using?

00:15:00
And what type of antenna and radio are

00:15:02
they using?

00:15:04
Right, it's one thing that you can get

00:15:05
out.

00:15:06
You've got 50 watts in a big antenna.

00:15:08
But if they don't have enough to get

00:15:10
back to you, they may hear you, but

00:15:12
you may not be able to hear them.

00:15:14
Suburban areas, you may get three to five

00:15:16
miles again.

00:15:18
What's in between you and the other station?

00:15:20
Open ground rural 10 to 15 miles.

00:15:23
I think that's kind of a stretch.

00:15:24
But you got repeaters?

00:15:27
Well, if you can get to the repeater,

00:15:29
however large the footprint of the repeater is,

00:15:32
is how far you can talk, maybe 20,

00:15:33
30, 50 miles, depending on the height of

00:15:36
the repeater and its footprint.

00:15:38
So, you know, you don't, you can't judge

00:15:41
by what the box says.

00:15:43
You can't judge by what the Amazon description

00:15:47
says.

00:15:48
You're going to have to judge it by

00:15:49
the terrain it's going to be used in

00:15:50
how you're going to use it, how your

00:15:52
antennas are going to be situated.

00:15:55
If you live in hills, or if you

00:15:57
live in a wooded area forested area, it's

00:15:59
going to eat your signal up pretty good.

00:16:01
But if you live out on the flat

00:16:02
plains, we've mentioned a hundred times, or maybe

00:16:05
down even near the coast where it's just

00:16:06
flatter, you're going to, you're going to be

00:16:08
shocked.

00:16:09
But again, it's still going to depend on

00:16:10
your antennas.

00:16:12
Are you guys tired of hearing me say

00:16:13
that yet?

00:16:14
It's the antenna.

00:16:15
Alright, so if you want to take it,

00:16:17
if you want to make a test, you

00:16:18
and your, your partner, your, your wife, your

00:16:20
spouse, your oldest kid, whatever, you stand them

00:16:25
there in the front yard and you get

00:16:26
in the car and you take off and

00:16:28
you go a certain direction and see how

00:16:29
far you can talk.

00:16:30
And then when you get to the end

00:16:31
of the neighborhood and you're like, man, I

00:16:32
can't talk any further.

00:16:34
Then say, well, what would it be like

00:16:35
if I had an elevator antenna on the

00:16:37
house?

00:16:38
It's worth the 70 or 80 bucks you'll

00:16:39
spend, I promise.

00:16:41
You probably should run tests like this.

00:16:43
So if you buy your stuff and you

00:16:45
get your license and you're, you're wanting to

00:16:46
see how far we can go, and all

00:16:50
you have is walkie-talkies, we'll try it

00:16:51
with walkie-talkies.

00:16:52
And then say, well, what if I put

00:16:54
a magnet antenna on my car and connected

00:16:56
it to my walkie-talkie?

00:16:58
That'll make a difference.

00:17:00
What about if I put my walkie-talkie

00:17:01
connected at home to an external antenna that's

00:17:04
on the chimney?

00:17:05
Big difference.

00:17:07
And test it that way and see what's

00:17:09
working best for you.

00:17:11
And that way you'll know when I go

00:17:12
to the office, I can call back home.

00:17:15
It might be that you have a nice

00:17:16
little base station at home and you work

00:17:19
on the 12th to 13th floor of some,

00:17:21
some building and you take a walkie-talkie

00:17:24
in and from that elevation to your elevated

00:17:27
antenna at home, you might have an intercom.

00:17:29
It'd be great, but you won't know till

00:17:30
you test, right?

00:17:32
And again, oh, antennas, antennas, antennas.

00:17:36
Yes, it's, oh man, this is in Ham

00:17:40
Radio and CB radio and these GMRS radios.

00:17:44
All these hobbies you find, the last thing

00:17:48
that anybody wants to talk about is the

00:17:50
most important thing anybody wants to talk about

00:17:52
and that's the antenna.

00:17:54
Again, I'm sorry, we're going to have to

00:17:56
stay there for just a minute because I

00:17:59
like in the amateur radio hobby, Ham Radio.

00:18:01
We have these guys and they'll go by

00:18:02
these, you know, $4 Ham radios to

00:18:06
put in their radio shack, their room, where

00:18:08
all their radios are and they'll connect it

00:18:11
to this junky antenna and they'll get online,

00:18:14
oh, this is the worst radio.

00:18:15
I made the biggest mistake ever spending all

00:18:18
this money and I got a junky antenna

00:18:20
or these guys buy these really nice BTEC

00:18:24
GMRS Pro radios and they're like, man, I

00:18:27
just wish it would perform better and they're

00:18:28
still using the factory antenna, which is a

00:18:30
good antenna by the way, but those can

00:18:32
be replaced with an even better antenna.

00:18:36
So don't get hung up on buying more

00:18:40
stuff or if you buy something and it

00:18:42
doesn't work as well as you thought it

00:18:44
would, have you tried the antenna yet?

00:18:46
Have you tried to replace the antenna?

00:18:48
Have you tried to use something better than

00:18:50
what came with it?

00:18:52
Don't go buy another, this was a huge

00:18:55
Instagram post of mine a while back, don't

00:18:57
go buy another radio, buy something to make

00:19:00
the radio you have perform better.

00:19:03
So the little rubber duckies that come with

00:19:04
the radios out of the box, they're not

00:19:07
the best, I mean they will transmit, they

00:19:08
will receive, but they're in the large part,

00:19:13
they're not great, some of them are huge

00:19:19
people to find an alternative antenna.

00:19:21
Of course, I recommend the ZBM2 QP whip,

00:19:25
it's thick, it works great and you can

00:19:27
save some money with prep comms coupon code.

00:19:30
Link in the show notes.

00:19:32
Another one that we're carrying in our store

00:19:34
now, just sold out yesterday, is the Wilcom's

00:19:38
roll-up J-pole, now for MERS and

00:19:42
GMRS. So we have the ham radio version

00:19:44
and the MERS, GMRS, we're backstocking that now.

00:19:50
And then there's, Centerfire Antenna makes a great

00:19:53
one, I put it in the show notes,

00:19:55
it's a tunable ground wave, a quarter wave

00:19:58
sorry, a quarter wave antenna to use on

00:20:01
those frequencies.

00:20:02
So another great way, you can get on

00:20:05
Amazon, there'll be show note links, I mean

00:20:07
it's all out there, you're gonna spend money,

00:20:10
you're gonna, if you're not spending more for

00:20:13
your antenna than you are your radio, you're

00:20:16
kind of doing it wrong.

00:20:17
Especially when it comes to these little $20,

00:20:19
$40, $50 walkie talkies, if you can replace

00:20:23
and improve the antenna and it doesn't cost

00:20:25
you more than the radio itself, you still

00:20:29
didn't do it up.

00:20:30
Oh man, everybody hates that, it's like the

00:20:32
water filter business, nobody wants to buy a

00:20:34
water filter because it's not sexy and you

00:20:36
can't talk about it and it just sits

00:20:38
there and makes clean water, but you have

00:20:40
to have clean water to survive.

00:20:42
Check the show notes, you can exponentially increase

00:20:47
the range of your radios by just swapping

00:20:49
the antennas, maybe stepping on top of the

00:20:51
roof of your truck, maybe going to a

00:20:55
couple of floors up in a building, height

00:20:59
over ground level with a great antenna, it's

00:21:03
like putting a supercharger on the 392 charger,

00:21:08
I don't know, those sound great by the

00:21:10
way, and it's really, you go spend more

00:21:13
money than you think you should, but the

00:21:14
results are gonna be fantastic.

00:21:16
Alright, so we're getting close here, let's talk

00:21:20
simplex repeaters, simplex and repeaters, so there's two

00:21:24
ways to talk on GMRS, we've talked a

00:21:26
little bit about this before, but sometimes it

00:21:28
still messes with people, they don't know the

00:21:30
terms and it doesn't make you a dummy

00:21:32
that you don't know the terms, you're not

00:21:34
a radio guy, maybe, maybe you are, but

00:21:36
the term simplex, alright, and just think about

00:21:39
it, take the X off of it, it's

00:21:41
simple, and what the term simplex means is

00:21:45
you're talking directly from one radio to another

00:21:49
radio on the same frequency, alright, so when

00:21:52
you and your kids are in the backyard

00:21:54
playing with the walkie talkies, you're talking simplex,

00:21:58
when you're talking on the CB radio to

00:22:00
another station, you're talking simplex, when you're using

00:22:03
MERS radios at your job at Costco, talking

00:22:07
to the guy at the front while you're,

00:22:09
you know, breaking down boxes, you're using simplex,

00:22:12
one radio to another radio on the same

00:22:14
frequency, that's it, that's what simplex means, you

00:22:18
see how simple that is, simplex, one radio

00:22:22
to the next, there's nothing in between you

00:22:24
guys except space, right, the other option is

00:22:28
repeaters, and these things are usually on very

00:22:32
tall towers or maybe a mountaintop if you

00:22:34
live nearby, and they listen on one frequency

00:22:37
all the time they're listening, and whatever they

00:22:40
hear, they are rebroadcasting or repeating that same

00:22:45
thing on another frequency, alright, so on GMRS

00:22:49
is typically listening on 467 megahertz and retransmitting

00:22:53
at the same time on 462 megahertz, okay,

00:22:59
does that make any sense, it's listening on

00:23:03
one, so when you press the push to

00:23:06
talk button it transmits on frequency A, the

00:23:10
repeater receives it and then retransmits it on

00:23:14
frequency B, which your radio is programmed to

00:23:17
be listening to, it only changes frequencies when

00:23:21
you press your push to talk button, and

00:23:24
they're programmed that way, and they're meant to

00:23:26
work that way, it allows you to repeat

00:23:30
what you're saying over a broader area, so

00:23:35
we got simplex, you and the kids in

00:23:37
the backyard, radio to radio, repeaters, you in

00:23:41
the backyard to the repeater, your buddy on

00:23:44
the other side of the town listening and

00:23:47
hearing you, they can literally take your little

00:23:50
five mile bubble that you've built with your

00:23:53
simplex GMRS radios, you stretch it across the

00:23:56
county, some multiple counties, but you got to

00:24:00
remember that people have paid for this equipment,

00:24:04
they've bought it, they've installed it, they've serviced

00:24:06
it, they maintain it, they pay the bills,

00:24:09
they pay for the tower rent, they make

00:24:11
sure that the antenna is operable, everything, and

00:24:15
generally what they ask you to do is

00:24:18
to ask for permission to use that system,

00:24:21
and it's pretty simple, there's some websites I'll

00:24:23
link it in, I think it's my GMRS

00:24:25
.com, but they've got the different repeaters and

00:24:28
different geographical areas around the US and who

00:24:30
to contact and ask permission to use, and

00:24:33
some people may say okay you can use

00:24:34
it, but what are you gonna be using

00:24:35
it with, they want to know what equipment

00:24:37
you have and whatnot, so if that offends

00:24:40
you, I don't know what to tell you,

00:24:42
it's their stuff, it's their sandbox, the biggest

00:24:45
thing to do is remember to always add

00:24:47
to yourself on the repeaters properly, and follow

00:24:51
their etiquette, they may have certain rules where

00:24:53
you know they want you to say your

00:24:56
call sign in your name, or it might

00:24:57
just be the number part of your call

00:25:01
sign, I don't know, it's their sandbox, you

00:25:03
guys will have to learn how to play

00:25:04
in their sandbox with their sand, so we're

00:25:08
going to get more into repeaters, how to

00:25:10
find them, how to connect them, and how

00:25:11
to talk to those folks, and make sure

00:25:14
you're not getting in the way, or doing

00:25:15
it wrong, or offending people, and you know

00:25:17
well it's America, I get that, but these,

00:25:20
this is somebody's stuff that they've bought, they've

00:25:22
spent thousands of dollars on, they're paying a

00:25:24
monthly power bill they probably never ask you

00:25:26
to contribute to, and all they're asking you

00:25:29
to do is to do it the way

00:25:30
they want it done, so simple, we'll talk

00:25:32
more about it next time, just leave your

00:25:34
fence at the door, because I'm trying to

00:25:36
help you, I'm really trying to help you

00:25:38
get this to make it work for you

00:25:40
and your family, and it might be like

00:25:43
well I don't want that, I want my

00:25:44
own, but that's great, find you a mountaintop,

00:25:47
I can help you with the equipment, when

00:25:49
get you plugged in, get you started, and

00:25:50
you have your own private repeater, and then

00:25:52
you can determine who is and who's not

00:25:54
on there, I mean I don't know, other

00:25:55
than that what are you going to do,

00:25:57
that's a great thing about these radio services,

00:26:00
that's what I love about them in regards

00:26:01
to preparedness, is it there, like in the

00:26:04
amateur radio community, we build our own infrastructure,

00:26:07
with the GMRS folks, they're building their own

00:26:09
infrastructure, and it's out there, and they're opening

00:26:13
it up for the majority of people to

00:26:14
use, they just ask that you follow their

00:26:17
rules, which coincide with the FCC rules, I

00:26:20
don't think it's too much to ask, I

00:26:22
am that guy, alright so here's what you

00:26:24
got to remember before we go, I've gone

00:26:25
long, I say that every time and I

00:26:27
apologize, the more power helps, so the 50

00:26:30
watts that you can get on GMRS, yeah

00:26:32
thumbs up, more power, but don't forget that

00:26:35
height and a better antenna is always going

00:26:38
to trump the extra power, remember it's not

00:26:42
about gear, you got to know the limits

00:26:44
before you need to use them, so if

00:26:47
you're building a system for your family, you

00:26:49
really need to be testing this stuff, you

00:26:52
really need to be testing with it, if

00:26:54
you haven't got your GMRS license yet, it

00:26:56
might be because the government is still shut

00:26:58
down, but that doesn't mean that you can't

00:27:00
apply, and as soon as they open up,

00:27:03
you'll be in the queue and you can

00:27:04
get your license, so check the show notes,

00:27:07
I've built a license express guide, and the

00:27:10
FCC I said it last time, their website

00:27:13
is terrible, it can be so frustrating, even

00:27:16
the people who use it a lot, so

00:27:17
these, I built this guide, there's a set

00:27:21
of prompts, and you follow the prompts, and

00:27:23
it tells you exactly where to click, what

00:27:24
to click, what to put in the boxes,

00:27:25
and you can get, you know, get prepared

00:27:27
to get your license, don't forget on Thursday

00:27:29
nights, on Facebook Live, I'm doing the Family

00:27:31
Connect System webinar, I have a replay from

00:27:34
Friday to Monday, if you want to learn

00:27:36
more about it, you can connect with me

00:27:37
there at familyconnectsystem.com, this is in the

00:27:40
show notes, but it's familyconnectsystem.com, where I

00:27:43
will teach you, and help you understand how

00:27:45
to build these systems for your family, anyway,

00:27:49
I'd love to have you there, it's Thursday

00:27:50
nights at 7 p.m. Eastern, because I'm

00:27:53
an Eastern time kind of guy, I'm Caleb

00:27:55
K4CDNWRBR237, I appreciate you being here, hope you've

00:27:59
enjoyed the show, thank you for the, for

00:28:01
the chats, and the comments, love hearing from

00:28:04
you, show this with your friends, your family,

00:28:06
everybody needs to be putting these things in

00:28:08
the place, because we don't know when it's

00:28:10
gonna stop working again, that sounds, that sounds

00:28:13
so fun, right guys, thank you again for

00:28:15
listening, 73, God bless.
