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 Jamie,
It won't use the same serial port both for controlling the rig's band/mode
and keying CW, as far as I can tell. I can get it to do one or the other but
not both. One solution might be to use two USB adapters and make up a
two-headed cable to split the K3 lines between the two ports.
Anyway, I was surprised just how nice it sounded compared to my K3.
The audio seems softer and warmer somehow. Same bandwidth (400Hz),
same phones. The K3 background noise just sounded harder, more harsh.
I've had this feeling from day one.
Have you played with Rx EQ? Add some bass,
Thanks, Terry! I'd been wondering what was rattling in my K3 but hadn't
found it yet. That was it. The connector was hanging up somewhere along its
length. I gently wiggled it and heard a small click as it slipped through.
Then I was able to tighten the knurled ring a little more and now it's
I notice a lot of black screws called out for internal construction of the
K3. I always thought the black screws were just for looks. So why are they
used inside? Strength? Corrosion resistance? Just because?

Grounds can serve three purposes: lightning protection, power line
safety, or RF ground. These are three very different things, requiring
very different ground methods.

True.
But should we go a step further and avoid even using the phrase RF ground?

Oooohh this brings back painful memories, but thankfully they are somewhat

it only read the (fairly accurate) RTC at boot and used the much less
accurate CPU clock to keep time thereafter, and 2) if you used the clock

to save and restore a small number (somewhere from 1 to 4) of configurations

My opinion is that a Morse decoder does more harm than good for a
learner. Maybe it might be helpful for those first few terrifying QSOs
(which are still quite vivid in my memory), but I think that the learner
would be far better off learning to trust his or her own decoding
apparatus.

For tuning amplifiers many of us use a string of high speed dits so the amp
can run at full instantaneous power while keeping average power down. It's
easier on the tubes and you don't need such a stout dummy load. TRLog has a

In many rigs the VOX control will perform the OFF function you're looking
for. With VOX off you'll need to push a Transmit button or supply an
external PTT signal to activate the transmitter. I haven't read the manual
yet but I bet the K3 works the same way.
OFF is a very good idea when you're
Let us be clear. There are two questions in this discussion.
#1. Can you use external PTT to put the rig in CW transmit mode, bypassing
both the full and semi QSK? This has been resoundly answered Yes!
#2. Can you arrange for the CW key to be disabled when the foot switch is
NOT pressed? I don't
I too vote for a QSK OFF state to accomplish this -- it seems the most
convenient way that I can think of
My ICOM 735 uses VOX for this - it becomes KOX in CW mode. But I don't
like that very well because when I switch to phone the VOX will be on and I
dislike VOX. I guess that using VOX would
