Symptoms
- Constant hiss or static with no clear audio
- Static cuts in and out as you move
- Volume seems fine but sound is unclear
Likely causes
- CommonSquelch level set too lowSquelch that's too open lets background noise through between transmissions.
- CommonWeak or out-of-range signalDistance, terrain, or buildings can weaken the signal enough to cause static.
- PossibleSlightly off-frequency tuningEven a small frequency mismatch can add noise to reception.
- PossibleDamaged or loose antennaA poor antenna connection reduces signal quality noticeably.
- Less commonInterference from nearby electronicsOther devices transmitting nearby can create noise on similar frequencies.
What to do
- Adjust the squelch dial or setting up slightly to cut background noise.
- Confirm you're tuned to the exact correct frequency.
- Move to a location with a clearer line of sight to the other radio or repeater.
- Check the antenna is tightly attached and undamaged.
- Try a different, known-good antenna if available.
- Move away from other powered electronics that could be causing interference.
- Reset the radio to factory settings if squelch or tuning seem inconsistent.

When to call a pro
If static continues on a correct frequency with a good antenna and adjusted squelch, a radio technician can check the receiver circuitry.
