I already have one, plus a bunch of the random-wire tuners. It was used as a bench mule for a S/W development place (as I understand...) so this unit had every accessory installed with the exception of the 1KHz RTTY filter. Just so happens I had one laying around.

Well, yeah, I mean, who doesn’t have a 1KHz RTTY filter laying around the shack, right?

Back to the QDX: Are you planning on using an external antenna tuner with it - and if so, what?

I am planning on an external tuner but I haven’t decided on which one yet. I enjoyed building the QDX so much that I’d like to build another kit but so far I haven seen one that really tickles my fancy. They are simple enough to design and build from scratch but I don’t much enjoy gathering parts from all over the globe via mail and the San Diego HRO closed last month.

I have a NOS Icom AH-4 automatic tuner up in my storage locker but there’s no way to interface it to the QDX as far as I can figure, at least not without some fancy intermediary circuitry (see above, re: gathering parts).
