Initial receiver testing on 40 Meters (pg 67) can barely hear XG2/XG3 @ 50uV. I've injected the 50uV from the XG2 directly to the input of the rcv. mixer Z6 @ R73, no change. VFO Input to the receive mixer looks good on a scope, no IF signal to be found at pin 1 of J12. Q22 voltages nominal.
I've eyeballed all solder connections and Caps and Resistors and confirmed values. We have confirmed the injection and testing procedure on a known good K2, lots of IF signal at J12 pin 1. Looks like Z6 is the problem? Any other ideas or thoughts? 73, KC2VMP Rob Gault ______________________________________________________________ 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
