Hi, I've hit a snag during 40m tx alignment in being unable to peak L1/L2 to give more than about 500mW o/p with the power setting at 2W. I've gone through the troubleshooting procedure & all checks out ok until I get to the LPF,BPF & T-R switch section of the shared circuit testing.
Using the 10Mhz crystal oscillator in the manual with 0.14V at the antenna i/p I get these readings: LPF o/p @ W1 = 0.004V (expected 0.13V) T-R sw #1 o/p @ W6 = 0.003V (expected 0.093V) BPF o/p @ left side of D6 = 0.003V (expected 0.086V) T-R sw #2 o/p @ right side D6 = 0.002V (0.077V) I don't know if it's relevant but the current display in rx mode is higher than the suggested values: 11.8V 0.36A (LCD nite, graph bar) 11.8V 0.30A (LCD day, graph dot) Any advice would be appreciated. 73 Brian G0WZX ______________________________________________________________ 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
