I can add that the UHF final is at least one of the easier ones to swap out in the 7000.

The 7000 uses separate finals for HF, VHF and UHF but the same driver. I you get full power output on HF and VHF, I bet the UHF PA is gone. It’s an RD60HUF-1 and they go bad for some reason.

I have a used IC-7000 and am concerned about the UHF FM transmit power. I think it might have a problem now that I've tested it with a watt/SWR meter.
I know that the UHF spec is lower (35W), but it takes 80% RF power to get only 5W. At 50% RF power I get about half a watt out. To compare, it only takes 15% to get 5W on VHF FM SWR is effectively 1:1 on both bands.
Is this normal or is something probably fried on the UHF side?
