Got a TKR-850 that was abandoned at a tower site.. powers on and transmits fine (can transmit using CW ID button and getting 25w output) but receive appears deaf, Busy light is staying on and can't key it up with any amount of power. Tried both ham and GMRS frequencies, both exhibit the same behavior. Checked all the usual settings and can't get it to go away. Any ideas of anything else to check before I say she's dead and just plan on using a mobile for receive?
