So are you using a seperate TX and RX then? Curious.
No, most of the time I'm using a Ten Tec transceiver of some kind.
But I also have some separate much older separate T/R setups and the QSK is truly seamless there. Look in a 60's ARRL Handbook for typical full-QSK setups. I hear my own note on the band when my key is down, and I hear the band when the key is up, no clicks, no clunks, no AGC pumps, a completely smooth transition. Getting the receiver muting set up correctly is actually hard in AGC-controlled receivers; the best way to set it up is to take it out of AGC, and have a separate QSK muting input added that controls the bias on the front end and mixer tubes.
The Ten Tec transceivers have excellent QSK... for a transceiver. But it's not seamless. If you look at the architecture of a transceiver you see why, the IF chain flops between R and T and back to R on every dit. Good QSK transceivers do this quickly without AGC pumping and with most of the switching done during mute and with a sidetone. But still not as good as separate T/R QSK, where you hear your own actual note on the band while key down.
