> I have to concur, but can?t give any help on what might be shorting. One piece of info I can give - there is no scenario in firmware where a fault will power off the amplifier. All faults will leave the amplifier in the STBY state with the amplifier on. With some you won?t be able to transmit, but the amp will still be powered.
