Chuck,
Make certain you have a dummy load connected to the K1 (it is
transmitting) and continually tap the WPM- button to try to lower the
power level for the testing that you need to do.
Theory:
The K1 uses one MCU pin (KEYIN) as an analog input to determine whether

If you switch the amp using PTT, you can adjust the delay from end of

According to the latest manual I have downloaded (Rev. D2), PTT RLS has
no effect in the CW mode.
If this has been changed, it is cause for celebration.
Hi Don,
Your comment about using flux cleaner struck a nerve with me.? I didn't have
any cleaner at the time of completion and obtained some a while back.? I don't

Chuck,
I don't recall the exact release timing, RF will always cease *before*
the drop of KEYOUT , so the amp relay should still be engaged when RF
ceases. That is true for both PTT and QSK.
Unless you can create a relay that drops out before its coil voltage is
removed, I cannot ever see a
Chuck,
Flux cleaners are *not* recommended for that very reason. The flux
residue by itself is non-conductive, but when combined with a cleaner,
it can create high resistance (leakage) paths unless it is completely
removed. Flushing an area with cleaner is almost certain to cause
trouble,
I read Chuck's description of his problem, and I thought, What in the

OK - I was responding to the original stated concern that RF might still
be present when the amp relay drops (at least that is how I interpreted
the original question) - and that is what will not happen.
As far as not having the amp relay drop out between words at 30 WPM,

Yesterday I changed PTT-KEY to OFF- DTR so Logger32 would be able to key via

Steve,
There was a 'safety valve' added to the K3 a while back that prevented
RF if the K3 was turned on while PTT or a closed Key was found.
Apparently, the timing of both the K3 power on and your PC boot were
close enough to activate that 'safety valve', but in an unusual manner.

I don't know the answer, but usually PTT used with phone or data does
not present a problem similar to your preferences for semi-break-in CW.
Perhaps someone who has experimented with that aspect and made
