Don,
Humm... Well, I did a few tests and, unless I've messed up a lot
(Who? Me?!!), looks like the transmit frequency is *not* offset by 600
(as the STP adjustment indicated). Looks like it's more like 200 Hz.
And, if I change the offset to 500 (lowest it'll go), I'm not sure there
is any change. I'll have to play with this more. But, assuming my
numbers are about right, I'm fairly sure there isn't anything I can do
about it... No?
Regards,

Kurt,
Check your KX1 menu setting for the STP parameter - the KX1 should
offset by that amount during transmit.
When you said "I knew I was on the calling stations frequency" - do
you mean that you tuned the station to the same audio frequency as
your STP menu parameter? If so, then your transmit signal should be
right on the other stations frequency. The menu setting tells the
firmware how much to offset but there is an expectation that you will
also tune the other station to that same audio pitch.
Be aware that many other operators do not know how to zero beat, nor
what it really means - they have been using transceivers too long. In
fact, I recall one ham who stated "I can hear him in my receiver, so
he will hear me!" Maybe it is time for zero beating lessons on the
air (sorry for the rant).
You may want to run a test if you have any doubts - tune in a signal
on another receiver and tune the same signal on your KX1 - then
without changing the KX1 VFO, connect a dummy load and transmit while
listening to your signal in the other receiver - if everything is
correct, you should hear your signal at the same note as the original
signal you tuned to.

Hi,
First, FYI: this is cross-posted to the Elecraft reflector and the
SKCC group.
I "played" on the SS the weekend. Attained 63 contacts QRP (KX-1).
I was mostly giving out points as I probably won't submit my log...
But, anyway...
While attempting to respond to a station, I was using a spectrum
program so I knew I was on the calling stations frequency (in this
case, I believe the KX-1 uses a 600 Hz offset - I've tested it with
another radio and it seems correct). So, here's the "strange" part:
If I zero beat the calling station, there was about a 1 in 10 chance
they'd hear me! If, on-the-other-paw, I tuned to about 450 or 500 Hz,
they seemed to hear me okay! And this included stations who were
answering on their exact frequency! I first noted this when calling
one station, but heard my call at about a 100 Hz tone (which meant my
sig was 500 Hz below him). I thought, "Huh?" Well, it works out well,
because the bandwidth filters seem centered on about 450 Hz when at
it's narrowest, but the question is, why was this? I mean I fully
expected stations to be listening on their own frequency first, then
offsets. Or, am I missing something? {'-)
