Mike, If resistor R50 is open, in most cases you will have very little (less than 1 watt) output. My best guess is that one of the PA transistors opened up when you encountered a very high SWR. When experimenting with antennas, it is best to keep the power down to one or two watts. When practicing CW, either turn the power all the way down or put it into CW Test (Hold the MODE button). Caution, CW Test is turned off if you power cycle the K2.
You can do Transmit Signal Tracing at any power level, but the Expected values in the manual will not be what is listed unless the power is set to 5 watts AND the K2 is not capable of producing 5 watts. 73, Don W3FPR On 9/16/2011 4:49 PM, vicki glover wrote: > Hello all, > I don't think my K2 is developing normal output power.
