I have a couple of Baofeng UV-5R radios. I have a profile in Chirp that works great on one of them, and I foolishly pushed that profile straight over to a UV-5R without checking firmware versions. Chirp crashed, and now the radio won't receive. I've tried resetting it to factory settings, downloading the factory settings in chirp, and then importing a csv of my channel configs, but it still doesn't make noise when I transmit.

I have noticed that it does receive when I hold the MONI button, but there's no indication of reception if I don't hold that button down. It appears to behave like the squelch setting is too high, but it's currently set to 3.

For what it's worth, the radio still transmits just fine.
