My pair of K3's also worked well in the RTTY Roundup - 1800 qso's. There are only a couple of issues that I saw:
1. On each transition between mark/space, there is a brief upward power excursion. One of my amplifiers has an LED wattmeter, and one of the LED's was blinking like crazy. Also, the screen current on that amp was varying significantly. I've complained about this in the past. Elecraft is supposed to be working on it. 2. When you reduce the DSP bandwidth to 300 Hz, it is not possible for me to get the audio output exactly centered between the RTTY modem's mark and space detector. The SHIFT control is too coarse. One click of the SHIFT control moves the audio either slightly left of center, or slightly right of center. It would be nice if there were a "fine mode" setting for the SHIFT control. I can live with both of these issues, but fixing them would make this rig absolutely perfect for RTTY, at least for me.

I just about cleared a thousand Qs this weekend in the RU in only 17 hours of on-the-air time. The K3 was spectacular in performance. The RX is magnificent and copied signals that I could not hear out of the speaker but printed on the screen. This happened many times. From Kansas, I did get to work some deep Europeans and even Israel called me. I did not hear any Russian stations at all. The DX was weak but workable. Magnificent RX. The TX was healthing and robust. I was running my amp so I was only running about 60 watts or less. The TX stayed cool and stable. The only issue I noticed was that between Dual PB on and off...the power would drop about 200 watts. No big deal, but interesting phenomonon. With the Dual PB on...the power would drop...with it off...the power would return to normal. Wayne and Eric already know about this issue. Thanks to all who worked me. Fun contest.
