I'm running into a problem with the resistance checks for the K2 Front Panel
Board. Specifically, I'm getting 0 reading from J1(1) - J1(7) and J1(12) -
J1(14).
My readings:
PIN // Expected // Actual
U1(1) // 25k-35k // 29.4k (GOOD)
U1(2) // 25k-35k // 29.5k (GOOD)
U1(3) // 40k-60k //
Just got a shiny new KXPA100.
I’m using “tight” integration with my KX3. The one downside I’ve observed is
that when PA Mode is On, the cursor display on the PX3 gets jerky and doesn’t
follow well. It isn’t terrible, just jerky. I assume this is the result of
the KXPA adding data load thro
Sorry about this! I got it out and set it up to check it out before selling
it and found it has a problem.

James,
I would not worry about the reading at J1 pin 15, but the others
indicate a problem.
I do not know of your soldering skills, but it would seem that your
solder is bleeding over enough to contact the ground plane that
surrounds the connector and other solder pads on the board.
If you
Grant,
Don’t know if it’s normal behavior but my setup is exactly like yours and the
behavior is the same. Especially noticeable at a high tuning rate. I bought the
KXPA100 from an individual but it had never been used, essentially new.

Thanks. That answers my question. You’re right, it’s close enough if you’re
tuning slowly, but if you try to tune quickly the PX3 cursor doesn’t follow so
well.

Grant,
Something else I've noticed since getting the KXPA100 is the Select knob on
the PX3 gets flaky if it's turned too fast. It seems to work fine if you
turn it slowly. For instance when setting the Ref Level if the Select
control is turned very fast the display just jitters and doesn't change
I fiddled with it a bit, and really didn’t notice any major changes in how the
PX3 controls function. Not that there aren’t any.
The simple solution is to simply set PA Mode: Off when generally tuning around.

Don,
Thanks. I see quite a few others on this board have had the same problems in
the past. I'm wondering if my multimeter is reading 0 ohms due to infinite
resistance. I'll take a look at my soldering and see what I find. I didn't
notice much during my previous look last night.
For reference:

Did the misc contributions from customers disappear from the new web
site? I was looking for the Elecraft CW Net info and can't find it.

Just out of curiosity, is the serial speed set to 38400? Running slower would
make a difference.

If the reading is actually zero - like when the leads are touched to
each other, then that is zero ohms, an indication of a short.
OTOH, if the reading is blank or whatever your ohmmeter reads when the
leads are attached to nothing, then that is an indication of infinite
resistance or something
Should have searched on Nabble first. Finally found some discussion of this
PX3 cursor lag issue when running a KXPA100 back in 2017.
Elecraft apparently recognized it as a bug, and talked about a fix, but I guess
nothing has been forthcoming.

Technician, know your tools! and know what the readings are telling you.
That is true both in the analog and the digital worlds.

What are you seeing on your DMM display? Many DMMs show a blank display
for an infinite resistance, while others show a "+" and others show
"OL".
Look at your DMM display when the leads are separated. That is infinite
resistance.
If the display actually shows "0", (same as with the leads shor
Good Evening,
Conditions lately have not been great. QSB is constant which is an
oxymoron. The noise level is not very high but neither are the signal
levels so it's a wash. The sun continues its inactivity.
I was not able to get to last week's net report so we'll start with that.
