I just finished building my KX1 and the receiver works great. I get 2W out on 40 but nothing measurable on 20. The odd thing is in receive on the base of Q4 I get 2x the signal on 20 that I do on 40; OTOH when I go into TUNE mode that signal ramps way up on 40 but remains insignificant on 20; by the collector of Q5 it's barely there. I checked the voltages on Q1/4/5/6 and they're OK, except that the source of Q1 is only 1.2V. I checked solder joints and they all seem fine; ditto inductors, though T1 looks to be a tricky bit of work.
Any suggestions would be greatly appreciated. I'd hoped to take this rig camping with me this Labor Day weekend, but it doesn't look like that's going to happen. 73, John K6YLG -- View this message in context: http://elecraft.365791.n2.nabble.com/40M-low-power-20-not-working-on-transmit-tp6756868p6756868.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
