[chirp_users] UV5RA+ unusable or noisy frequencies
Here are some of the frequencies my radios have trouble with,
do others get this or have more frequencies?
UV5RA+ with RH901 antenna frequencies you can not use unless squelch is set above 30/128 +-5 Khz 416.0 422.195 423.0 424.675 442.0 468.0
Are they unlisted beacons or internal ?
grid area FN96
Baofeng radios have a 26 MHz reference oscillator. The harmonics of 26 MHz in the receive range of most models would be: 104.0 130.0 156.0 416.0 442.0 468.0 494.0 520.0
There may be other "birdie" frequencies from other internal or external sources mixing.
What you receive can depend on how good or poor the shielding is on a model or particular radio and what type of antenna you use or if you remove the antenna.

Yup. My 5RV2+ has birdies at 416, 442, and 468 MHz (no antenna). Nothing on the other frequencies listed in the original message.

I tested outside in field away from electronics and nearest cell tower was 7km away
