Steve, I would be tempted to change the resistors to see if it makes any difference - it certainly will do no harm and has promise of correcting your problem. While you are inside the KPA100 shield, I would recommend that you also check the low pass filter for 15/12/10 meters - look for the proper number of turns on the toroids (count the turns that pass through the center of the core) and verify that the LPF capacitor values are correct.
I have not seen this low gain behavior on 15 meters and above, but the exact frequency depends on just how much inductance the resistors actually possess. 73, Don W3FPR > -----Original Message----- > > I purchased a recently built K2/100 this summer and am > gradually working my way through careful evaluations. > Today I checked the key-down current and found some > variations that look rather like those mentioned in > Builder Alert #22a. > ... > Do you think it would be useful to make the upgrade to > get it working as well as it can ?
