[amsat-bb] icom 821h problem

i have an icom 821h. sometimes when i turn it on, both the main and the sub band receive lights are flashing together from green to orange. when this happens, i can transmit fine but there is no audio. turn it on and off a bunch of times and nothing changes. then all of a sudden one day, it will work just fine. of course in the meantime, there is no audio on either band. adjusting the squelch all the way open or closed changes nothing. i can see the s-meter move when a signal is received so that works fine. any ideas?

please email me directly.
