CW PTT

Ken Kopp-2
You bet, I -LIKE- to use a foot switch on CW.  It lets
me pause ... for whatever reason ... longer than the
"normal" T/R time.  If an amp or other external gear
is involved it keeps everything from clunking and clattering
up/down.

I'm a newbie, just building S/N 5665 and I just assumed
I'd have PTT on CW .....

Thuis message will also show if my double-posting problem
is fixed (:-)

Aha! I hadn't considered driving a non-QSK amplifier. Tnx

You do have control over the TX delay or "hang". You can set the K2 to stay
in TX mode for up to 2.5 seconds after the key is released.

Ken,

There is an easy solution with a double pole relay.  Just run the paddle
lines through the relay contacts, and wire the realy coil in parallel with
the relay in your amp (it must use the same coil voltage as the one in your
amp).  Then use the footswitch to close both the AMP and the external relay.
If the paddle closures are not seen by the K2, it will not be keyed by the
paddles until the footswitch is operated.

BUT - I would think that the max delay of 2.5 seconds would be adequate so
you can run the K2 in 'semi-QSK' - the amp would only drop out on really
long pauses.

73,
Don W3FPR

Another way to accomplish this is to just parallel the foot switch with
the Key-out line from the K2 to your amp, instead of trying to key the
K2 with it. That way you can hold down the amp keying line and relay
during long CW TX pauses. (There is no need to hold down the K2's TX as
it does not have any T/R relays to clatter :-) Its a fully silent
break-in or semi break-in machine.
