Not sure if anyone else has noticed anything similar, but here is an interesting observation.

I have a cheap mfj travel paddle I was using to test the qsk and keyer functions. I'm using an end fed half wave, fed through a 4:1 balun, about 30ft of coax? tuner in the shack. Not ideal for qrp. I noticed that often when using the keyer, the speed reduces by one step each time I hit the key, going from 20 wpm, down to one. Interestingly, if I use my good paddle, the problem does not seem to occur. I have already checked that d3 and d4 are not shorted, as this could cause the problem...but if so, it would occur all the time, with the good key as well. Anyone else see anything like this?

Also, regarding My earlier comments regarding using an audio tone to generate cw...on my rig anyway,when tuning a strong signal, you do hear a fairly noticeable tone on the wrong side of zero beat, so I guess the filter would not be good enough to avoid an upper sidebar cw signal.
