Owen, Armed with that further information, I suspect the relay contacts. Examine the inductors anyway to see if there is any evidence of charred turns, if so, re-wind them.
You can check the relay contacts of K12 with an ohmmeter. If you set the K2 to 40 meters, Relay K12 should be in the position opposite that shown on the schematic. That means continuity between pins 7 and 8, and 3 and 4 - be aware that at DC, the entire low pass filter will measure as a short to ground unless you lift lead # 3 or #4 from T4. Many have drawn false conclusions because of this DC path to ground. On 11/7/2010 1:37 PM, Owen B. Mehegan wrote: > I just tried the test for the inductors.
