Ouch, 25 wpm is cw with training wheels. In the real world people don't send that slow. Bummer. I'll check out the site you referenced. I don't have a KDSP2, being a code kind of guy I am good to go with the KAF2. I love the receive qualities of my K2, and really, really wanted to make it my main HF rig. But if it isn't capable of QSK it can't take over Op Pos #1 for serious DXing. But I love the radio and it will get lots of non-DX use. QSK is the holy grail of cw ops. I am kicking myself as the best QSK I ever owned was a freak of nature. In the 1980's I had a Yaesu FT-757 GX II that held QSK beyond 40 wpm. Just the fluke of the components. But was it sweet to key! Joe N9JR

I suggest that you look at <http://www.qslnet.de/member/la3za/K2/mod.html> and look for related entries. I found that adding the DSP and the KPA100 complicates getting clean QSK. I don't want to go into detail, because my own observations have been inconsistent and I've made and unmade so many changes that I'm confused about what works and what doesn't! -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
