Re: Fan Noise
Hi Rich
With 1 KW out on 6 meters I think the second fan doesn't kick in until the

Re: Fan Noise
Are you guys talking at idle when you first turn it on or during operation?

Re: SWR High SSB ONLY - When Using LA-1K Amp
I have yet to try the band data cable although I have been told it does
help some issues.
