3881Re: [wsjtgroup] Power output reading when using WSJT modes?
- Aug 1, 2007Hi Bill,
What I believe you're seeing is "average" power
out. If you transmitted CW, RTTY or FM, you'd
see 500 watts. The WSJT tones are similar to
voice - you'll see an average power out, that may
hit 500 watts on peak. My guess is that all is
well. Just have fun with the contacts!
