I've searched the web but haven't found the answer to my
QRP CW question.

I'm looking for a QRP CW transmitter kit that includes QSK and
will mute a boatanchor receiver like an SB-303, SX-101, or 75S-1.

I realize that some receivers might not recover fast enough for
QSK.

I've looked at website ads for Ramsey, Vectronixs, and still
don't have an answer. They might do it out of the box; they
might do it with a mod but I haven't found the answer.

A couple watts of CW and capable of working with the WA6OTP PTO
kit.

Anyone got something like that working?

Quoting from the Vectronics VEC-1220K 20M transmitter kit manual, page
26: "Receiver Hook-up: You may patch most receivers directly into your
VEC QRP-CW Transmitter's receiver jack without risk of damage.
Transmitter output is typically around + 32 dBm and the energy
reaching your receiver through the T/R switch is normally 25 dB lower,
or about +7 dBm. This is a very strong signal, but a high-quality
receiver with a wide AGC range can usually handle it without blasting
out the speaker! If you are able to leave the receiver on during
transmit, you'll enjoy the benefit of full QSK operation."

"This means you'll be able to monitor incoming signals--and listen to
your own outgoing signal--simultaneously. If your receiver has an
attenuator switch, turning it on will help reduce the effects of
overload. By the same token, if your receiver has a pre-amplifier,
you should turn it off. Receivers unable to limit speaker or
headphone volume over a wide range of signal inputs must be turned
down or switched to standby mode while you send."

Enough said?
