Digital Modes, Text Messaging, Repeaters—and Why Clarity Matters
There’s power in knowing the limits.
Can MURS use repeaters or digital modes?
No. MURS does not allow repeaters, trunking, or wideband digital voice systems. It is limited to narrowband analog operation on five fixed frequencies. It is open for monitoring and offers no privacy protection. Any claim otherwise misunderstands FCC rules.
Let’s dig into what MURS can legally do, what it can’t, and why that matters for you and your family comms plan.
Digital Modes: Not All Are Forbidden
First, let’s clear something up:
Digital voice modes are prohibited. That means DMR, Yaesu Fusion, D-STAR, NXDN, P25, etc...—all off-limits.
But analog data or telemetry sent via FM is legal under specific conditions:
Fits within MURS bandwidth limits (11.25 or 20 kHz)
Sent via FM modulation
Manually controlled (no auto-beacons)
Not encrypted
This opens the door to RTTY, MT63, Contestia, and Packet, plus analog keyboard-to-keyboard texting tools like Rattlegram.
Legal nuance matters. And frankly just saying it's a 'gray area' was lazy on my part, I should have made that distinction sooner.
Can I Send Text on MURS?
Yes. Absolutely.
You can send text using:
Audio-over-FM tools (like Rattlegram)
Packet or MT63
Keyboard messaging apps that modulate in analog tones
What you can’t do is automate it, beacon, or piggyback a repeater.
So yes—texting is legal on MURS. No—it’s not private. And no, it can’t run on autopilot.
Keep it human. Keep it short. Keep it simple.
No Repeaters. Not Even Clever Ones.
FCC Rule 47 CFR §95.2705 says it plain:
“A MURS station must not be operated as a repeater station.”
That includes:
Same-band repeaters
Crossband relay setups
Digipeaters or iGates
Store-and-forward devices
Manual relay? Legal. Automated anything? Not legal.
And look—I know people are doing it anyway. But the rule is clear. And if you go that route, you’re on your own.
The Antenna is Still the Game-Changer
Here’s where most people get MURS wrong. They think the power limit (2 watts) makes it weak.
But it’s not about power. It’s about the antenna.
A well-placed 2-watt VHF station with good coax and a real antenna outperforms a 10-watt radio with junk gear every day of the week.

Final Thoughts
MURS isn’t a loophole. It’s a quiet, powerful tool.
When used with respect and understanding, it can bridge the gap for families needing basic comms that work—without licenses, repeaters, or headaches.
But it only works if we use it responsibly.
No beacons. No repeaters. No digital voice. But yes—you can do a whole lot more than you thought.
