Hi Tom,
On the K4, with full QSK selected, you can hear between dots at 40 WPM.
There's no need for a "QRQ" mode, as on the K3, because the K4 doesn't have to
update a synth between TX and RX.

When I send CW from the computer, I don't hear anything until the string
of characters is finished. I think that's due to my closing the PTT by

Hi Barry,
There is a lot of confusion and mis-information about the need for CW
keying loop feedback from the amplifier to the rig in the amateur
community. While certainly it was necessary on some older rig and amp
combinations, it is not necessary with a properly designed rig today
that has
K7GT obviously has the same concerns. Over the past decade I've used
a slew of Ten-Tec and Yaesu xcvrs interfaced to Ten-Tec, Alpha, and

The lack of QRO QSK with the K3 may be a big issue with some
prospective K3
Don and K3 fans,
I have a few comments on interfacing Elecraft transceivers with QSK amps.
When the K2 was first announced publicly (Oct 1999, Pacificon QRP forum)
Wayne and Eric invited those attending to give input and comments
regarding desired features. As I have been a Tentec fan for many ye
Barry,
For amplifier keying, the K3 has an adjustable T-R delay that is very
much longer than that provided by the K2. It may be easier to use that
than fooling around with the external TX inhibit function.
The TX inhibit is more useful to folks who operate VHF/UHF with a
sequencer to switch
Thanks Don. Although TX Inhibit is described in the latest C1 version
of the manual, I missed it because no mention is made of using it for
qsk amp control. It would have been nice to make +5V available on the
AUX I/O connector for the pullup wiring. Also, I'm not sure why the
manual text refers
Barry,
Something was added to provide a "TX inhibit until PTT" function. That
discussion was late in the Field Test cycle. I was involved on the
sidelines of the discussion even though I was not a field tester.
The bottom line is that it is "in there", but I have not combed the
latest docu
I'm surprised to notice no provision for tx enable/inhibit signals
(qsk keying loop) on the K3. I'd appreciate hearing comments on why
this wasn't part of the design and what the timing safeguards are in
the existing "key out" signal to prevent hot switching on make/break.
Thanks & 73,
Barry N1EU
