Same as what the LED's say when the highest one just comes on. > > Is the maximum output the same on all modes (CW/AM/FM etc.)? Yes, don't know about FM, never used it but it sounds like RTTY, see below. AM will have 50% of the power in the "carrier" [which "carries" nothing], and 25% in each of the two identical sidebands. PEP will be 500W. > > Is the maximum output the same on all bands (what happens on 30 > meters)?

It runs fine for me at about 2:1, then it trips off.

Don't do WSJT but I'm sure just fine. I have run it @500W in RTTY contests and watch the PA Temp. It rises, the fans come on, it goes back down. Does this all day, as long as I can keep my butt in the chair. I thought WSJT was a low power mode. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
