Hi all, I'm working on getting KX1 2846 up and running and have run into an issue with the transmit testing. I get zero power output into a 50 ohm dummy load. As it is right now, it is built only as the 20/40 meter with no ATU installed (the base kit).
I have run through the troubleshooting table and made sure: 1. R4 is fully clockwise (and there is a difference in level to a monitor KX3 nearby when this is adjusted). 2. J7 is jumped between pins 1 and 3 3. T1, L3, L1, and L2 are wound correctly and all have resistance of less than 1 ohm. When measuring the DC voltages across the transmitter: Q1 - (D) 13.85; (G) 0.31; (S) 1.61 Q4 - (E) 0.23; (B) 0.95 [with power out via the watt meter during measurement]; (C) 2.46 Q5 - (E) 3.71; (B) 2.45 [with power out during measurement]; (C) 13.85 Q6 - (C) 13.85 The Q5 emitter seems to be high with the other values close to those listed in the KX1 manual. I'm not sure what to make of the power out during the measurement other than a poor connection somewhere. I'll be contacting Elecraft for some help with the troubleshooting, but thought I'd ask the group in the mean time. Any suggestions would be appreciated. Thanks, Scott - W1ZU ______________________________________________________________ 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 Message delivered to [email protected]
