Hi Alan
Not in PSK D mode as we were running PSK65 so in AFSK A mode
So if it has an offset programmed in for PSK D mode then maybe AFSK A mode
has been an oversight
Anyone at Elecraft care to comment, I think AFSK A mode needs an offset of
1500hz in the P3 so you click and tune to the centre
Hi Jim,
AFSK A mode on the K3 assumes you are running FSK. The VFO frequency is
the frequency of the mark tone, which is 170 Hz / 2 = 85 Hz from the
center of the filter passband.

Jim,
I don't have a P3, so cannot comment directly on that aspect, but there
seems to be some confusion between DATA A and AFSK A in your latest
e-mail, which may obscure your message.
The mode normally used for PSK and other sound card digital modes is
DATA A. DATA A is an upper sideband
Anyone ??

Why not use your mouse and select signals in the PSK software?
You can select any of several signals this way that will be in your passband
and it will be right on the signal. You should not be QSYing your radio to
tune to different signals in the way you describe. This is just the wrong

Bob et al,
This is not the way I operate in contests, I use the K3's excellent filters!
Scenario:-
If 1 very strong station is close to 3 weak stations you will not copy the weak
stations due to the strong station shutting the ALC down, so narrow the filters
right up and hey, there are the
Jim,
I thought I saw a post in answer to your comment about QSY in data mode, but
perhaps it was an answer in another thread.
The poster said he noticed that when he tapped the knob on the P3 he was
rotating it very slightly. After seeing this he said he set one of the function
buttons to TAP
Hi Jim,
I'm not seeing the problem. With the K3 set up for PSK D data mode and
normalized bandwidth and offset, if I click-to-QSY on a carrier with the
P3, the carrier ends up right in the center of the K3 passband.
Could you tell me exactly how you have the K3 and P3 set up? What

Just setting up for PSK contest and notice that the tap to QSO is not accurate,
ie if I tap to qsy to the scope peak for a PSK signal with the filters narrow
to say 0.2 the signal it well outside the filter pass band
Is there any way of changing this so the signal arrives in the passband
I find when I tap the SELECT knob to QSY I sometimes rotate it a bit so
I set one of the function keys to Knob Tap to solve that problem.
