[Elecraft] K2 Alignment Problems
Hello all, Have made it to the first Alignment on the K2 and am not getting the appropriate 12.096 +/- reading. What I am seeing is a reading in the 7 to 8 Mhz range drifting up and down. L31, as provided with my kit, is marked 10uH. I've gone over the soldering and components several times (which means I've probably missed something obvious). Any suggestions? 73, Julius n2wn ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] K2 Alignment Problems
Julius, Check the thermistor board VERY carefully for solder bridges. As a quick sanity check on the health of the thermistor board, measure the voltage at RF board U6 pin 4 - if is not close to 4 volts, you can be certian there is a thermistor board problem. Note: that does not fully check out the thermistor board, but it is only a quick first check. You can usually examine the back of the Thermistor Board by removing the Control Board and Front panel. 73, Don W3FPR -Original Message- Have made it to the first Alignment on the K2 and am not getting the appropriate 12.096 +/- reading.
