UV-5R Receive Range & Listening Boundaries
Know what it hears, what it misses, and the legal red line.
The UV-5R hears more than "two bands"
The UV-5R is sold as a dual-band (VHF 144–148 / UHF 420–450) HT, but its receive coverage is far wider: it is a broad-coverage receiver that can listen to many signals outside the amateur bands. This page explains what it can hear, what it cannot, how to extend it, and the legal boundary.
One diagram: receive vs transmit bands
The UV-5R receives far more than it transmits: default VHF ~136–174 MHz and UHF ~400–520 MHz (CHIRP can lower the VHF floor to ~108 MHz for aviation AM), but its transmit is locked to the local amateur bands (2 m 144–148, 70 cm 430–440); 174–400 MHz is not received on most units. Figures are common approximations — follow your unit and region.
Default receive range
Most UV-5R units receive roughly 136–174 MHz (VHF) and 400–480 / 400–520 MHz (UHF); the exact upper edge varies slightly by batch/firmware (follow your unit). Within this you can hear: amateur, some marine VHF (156–162), aviation (if enabled), weather (162 MHz NOAA WX on some units), PMR446 / FRS / GMRS (446 / 462–467), and some commercial UHF.
What it cannot hear
- FM broadcast (76–108 MHz): too low in frequency for the UV-5R.
- AM medium-wave broadcast: outside its receive range.
- Cellular: band/mode not covered, and reception is restricted.
- Most digital trunking / encrypted: even if the frequency is in range, the UV-5R is an analogue FM radio and cannot decode digital/encrypted (e.g. TETRA, P25 digital, DMR time-slots need other gear).
For shortwave or full aviation coverage, the UV-5R falls short — use a wideband receiver or SDR instead.
Extending receive (incl. aviation AM)
Some UV-5R units start VHF at 136 MHz and cannot reach aviation (108–137 MHz, AM). You can lower the VHF floor to ~100/108 MHz via CHIRP’s “Receiver Limit” field or the radio menu, so you can listen to aviation AM; the UHF ceiling can also be pushed to 520. After doing so images and sensitivity drop noticeably — a normal trade-off.
What you can lawfully listen to
- Amateur repeaters / simplex: your home turf, free to monitor.
- NOAA WX weather: 162 MHz, free weather, receive-only.
- Aviation (if enabled): tower/aircraft chatter, a popular hobby target.
- Marine VHF: port / ship communications.
- PMR / FRS / GMRS etc.: receive-only of civilian walkie-talkies is allowed in many areas, but some regions restrict monitoring — check local rules first (see the local regulations page).
The receiver's weak spots
- Modest selectivity: near a strong signal it is easily pulled or intermodulated.
- Front-end overload: in dense city/base-station areas it saturates, strong local stations blanking weak distant ones.
- Images / spurious responses: a known trait of cheap RF front-ends, worse after extending the range.
- Limited sensitivity: weaker than a pro receiver; weak signals need an external antenna.
