I built a K1 as my first HF rig, and thoroughly enjoyed it. It's
limited, but within its limitations it's very good indeed. Since
your budget is $300, I'd recommend the two-band board on 20m and 40m,
and the 150K tuning range. There's CW activity well beyond 80, and

One of the original theories for the LSB/USB differences was brought about
by the use of a 9Mhz. IF frequency in some of the early SSB gear.
Originally, there was no voice modes at all on the 40 meter band. Also 15

I didn't address your budget very effectively. The 4 band K1 may be a bit

Carl, WinKeyer does something else. It takes ASCII
from the computer and converts that to code. No
program can do that very well if that program runs on
a computer that has a Windoze operating system because
Windows has its own priorities for interrupts. The
logging programs did the conversion
Someone kindly mentioned SR5 here so I downloaded it and observed that my
audio from the K3 had a pronounced peak around 1600 Hz. I compensated for
this by adjusting the K3's RX equalizer so that EQ (6) is -4db, EQ (7)
is -4db and EQ (8) is -2db. I now have a flat response across the spectrum.
Choppy or interrupted CW is a common complaint with software keyers in
logging progams. I have observed it myself. Maybe you can get around the
timing issue in Windows by writing it into a device driver (is that what
you're suggesting?) but apparently few people do it that way.

I've had several off-list responses about this telling me pretty much the
same thing:
The KY command that sends text to the internal keyer has been looked at
and deemed insufficient to support the demands of high performance contest
software. Too much latency on the serial bus, no way to sync up

Hi Jeremy,
I almost hesitate to answer your post since I'm a newbie and I don't know
nuthin' about nuthin'. Also, I don't have any experience with the K1, other
than having had a few QSOs with K1 operators. I've been on the air less than a
year, all CW, and all QRP. Having said all that,
I've been working the CW contest tonight on 80m with 1500w output to a half
sloper which is enclosed within an 80m full wave horizontal QSX loop which is up
20 feet, using full QSK with no appreciable unwanted effects. The scope trace
looks the same as using the TX antenna as the RX antenna!
