P3 signals disappearing

I use the SVGA with my P3, my eyes just don't see well enough to see
the screen on the P3. Something I have become more aware of lately is
I'll see a faint signal on the monitor and when I when I jump to it
with a click using marker A, there is no signal underneath the marker
any more. I usually operate CW and the P3 is usually set at a 1-3KHz
span.

For all the world it looks just like a very weak signal, the kind I
look for the most on the air but since it disappears from under the
marker when the button is tapped and nothing is heard when looking
for a signal, it has to be an artefact. If it remained and was not a
station but some RFI, I'd understand but since it disappears, it's
got to be an artefact generated in the system.

Not sure if this is what I've read as ghosting but it's sure a good
definition to describe it. ;)

Ideas?

73,

K3/0 PSK distortion

I'm using a new K3/0 mini and the remoteRig boxes to remote my K3.

I'm getting reports of my PSK looking like I'm over driving it.

I have my laptop soundcard level set down to 10 as recommended by
Brandon. When xmtg I set the ALC level to 4 with 5th flickering or even
just 4. If I go any lower I get no output.

Anybody have any idea what's going on?

thanks 73 Dwight NS9I

Re: K3/0 PSK distortion

Dwight,

You have the audio level set correctly if you are getting 4 bars on the
ALC meter with the 5th one flickering at times.
Are you using DATA A mode? If you are using USB mode, you must manually
turn off compression and set the equalizer flat. Using DATA A does that
automatically.
Another thing to consider is that the soundcard output of the laptop may
be distorted. You might try an external soundcard.
Do you have distortion in SSB voice operation? If no distortion in SSB,
there is likely nothing wrong with the K3.

Those are the only things I can think of at the moment - unless the
problem is with the receiving station.
One nice thing about remote operation (if the transmitter is really a
good distance from your control position), you can use another receiver
and computer to monitor your data mode signals yourself. A modest
antenna should do OK for receiving your signal so you may be able to
'sneak it' by the HOA or your building manager. Think stealth antennas
for portable work.

Re: K3/0 PSK distortion

Thanks foTalked with Elecraft and they sent me a paper on setting up the
different modes for the K3/0. One thing I was doing wrong was using Data
A when they recommend USB. Seems to be okay now with some more signal
reports.

Re: K3/0 PSK distortion

Dwight,

I don't have experience with Remote Rig, and Brandon's suggestions usurp
mine. One thing I know is that if you are using USB mode instead of
DATA A, you will have to set compression to zero and set the TX EQ to
flat. Failure to do that will result in distorted data transmissions.

73 es HNY,

Re: K3/0 PSK distortion

Got it Don, yes the paper was written by Brandon.

thanks much and HNY to you.
