Sounds strange but if you?have the original fuses better try cleaning them..? They will cause voltage drop when u transmit.???

Subject: [IC-7000] Strange issues with output power
?
Hi All.
I have had an Icom IC-7000 for over a year now, having bought it second hand. Today I went to use the for a few SSB QSOs on 20 metres when I realised I couldn't get more than 40 watts out.
Initially I thought that the PA amp may be at fault, but after playing around some more, I learned that the power I get varies wildly with band. Setting the radio to 100% power out, I get the following measured powers with a Bird Thruline into a dummy load:
- 160 metres, 1 watt.
- 80 metres, 1 watt.
- 40 meters, 10 watts.
- 20 metres, 40 watts.
- 12 metres, 60 watts.
- 10 metres, 90 watts.
- 6 metres, 30 watts.
- 2 metres, 49 watts (fine).
- 70 cms, 37 watts (fine).
It seems the issues are in the HF PA, i.e. anything on Antenna 1. I'm not sure what the issue is. I think something like a capacitor gone down, or a relay stuck? I'm not sure.
Any help would be greatly received.
Thanks in advance.
