My buddy K1VW, who is not on this reflector, asked me to look into a
problem with his K3, and I am turning to the reflector for assistance. John received a report from another station (not a local) of a spurious emission while transmitting CW on 160 meters. Evidently the spur was loud enough to attract some attention. I searched the reflector archives for the past six months and did find anything on this topic. The other station mentioned that this is a known problem with the K3, and that the fix involves clipping a diode. This is all second-hand information to me, and that is all I know about the situation. Any suggestions?

Walt,
I suggest that the K3 owner contact [hidden email] for assistance. Many on-the-air comments that I have heard pass along inaccurate information (about many subjects, not just the K3). The only K3 mods that I know about involving diodes are the KPA3 12V Sense Mod and theK3 VFO Noise Mod - these *add* diodes, and AFAIK, neither of these has been known to create spurs, and definitely do not involve "clipping a diode" - most of the K3 diodes are SMD, and I just cannot relate "clipping" to "removal" - methinks that fellow was misinformed. 73, Don W3FPR Walter Miller, AJ6T wrote: > My buddy K1VW, who is not on this reflector, asked me to look into a > problem with his K3, and I am turning to the reflector for assistance. > John received a report from another station (not a local) of a spurious > emission while transmitting CW on 160 meters.
