Re: IC7000 no HF Transmit
|
I received the radio in this condition.? The only evidence of rework from the previous owner was the rx/tx relay had been replaced.? Some of the thru holes for the relay leads had been disturbed.? Maybe the “no TX” issue was the reason the owner replaced the relay.? I removed the relay and closely inspected the traces and thru holes.? Everything seems to be intack.? As I mentioned, the receive works exceptional in all bands.? This tells me that all LPFs are working.? I tried the TX TOTAL GAIN adjustment procedure but no increase in power out. ? I am adding a couple of schematic views.? First is the rx/tx relay just beyond the PA circuit.? The second is the forward/reverse detector for the power control and SWR. ?
