KX3 Unwanted Scanning

I decided to get my new (to me) KX3 going on psk31. I ordered the proper
cables from Elecraft. Plugged the cables into the KX3 ("red" cable go to the
Phones jack; "green" cable goes to the Mic jack). Put the radio in data
mode ("PSK D" selected). The radio begins to scan, and will not stop until
I unplug the green cable going to the Mic jack). I tried this set up with
two different external soundcards and well as the one internal to the Sony
laptop; no joy. I also tried different digital software programs to see if
that was the problem; still no joy.

I checked the archives and did find a mention to this problem in 2015 but no
definitive answer. I am sure I am overlooking the obviously. I will be
happy to put on my dunce cap, once someone can point me in the right
direction.

Re: KX3 Unwanted Scanning

David,

Why did you select PSK D when you have anything plugged into the MIC
jack? See the DATA MODES section in the manual for more detailed
information, but "in brief":

PSK D does not respond to audio, but only to input from the paddles (in
CW which is converted to PSK signals) or from ASCII text sent over the
CAT cable.

You did not say what you have connected on the other end of those
cables, and that is an important piece of information.

If you have a soundcard connected to the other end of the cables, you
must use DATA A submode (or AFSK A for RTTY). Again, see the DATA MODES
section of the manual.

Since those cables have TRS plugs (and not TRRS plugs), you may have to
turn off MIC BTN and MIC BIAS in the KX3 menu.

73,
Don W3FPR

Re: KX3 Unwanted Scanning

I had some notes from a couple of years ago when I was plagued with this
scanning issue. My notes were a little incomplete. So, I embarked on a
few tests to narrow down the proper KX3 settings. Don had the right advice
for you - the secret sauce is the Data A mode.

The Mic Btn menu item can be set to anything. An additional observation is
that the mic bias and mic btn menu items will not be available to change
their values when in Data A. Mind you though, I also had the Mic Btn set
to just PTT (as Bill suggested) from a couple of years ago. But, today's
tests showed me scanning would happen regardless of the Mic Btn value.
FYI...I have the latest firmware on the KX3 (non-beta).

I did a few tests to prove my theory. Data A being set for any external
sound card hookup yielded no scanning. If the 'D' data modes were
selected, unplugging and plugging the mic cable (green), would result in a
short scan and then stop. I tried various values of mic bias and mic btn
and all had the same scanning effect when not in Data A mode.

regards,
Brian
