Re: UHF FM Transmit Power

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. ? Thank you, ? Paul W. Hansen, W6XA ? ?

Subject: [ic7000] UHF FM Transmit Power? Hello,
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?
73,
Mike
