Yesterday the radio just refused to operate on 122.7. Every other frequency we used in 3 hours of flying and 5 airport stops worked fine. It did not work in the air and it did not work on the ground even with a handheld next to the plane while debugging. It would not break squelch on RX and would not break my flying buddy's different radios squelches when I transmitted. Acted like there was a SW bug that blocked it out completely so I'm hoping someone else with the same radio can test it but then if it is a SW related issue, how would we be able to compare SW versions is another story all together...
