Elecraft K3 & P3 Strange Occurrence

[Mike VE3YF]

Hi:

I have something strange that just started to popup. The K3 is on a 80m
Freq of 3.755.00 and I also have the P3 turned on and it is reading the
same freq. Every so often (random) the Freq on the P3 will go to 0 and
then back to 3.755.00. The rest of the display is just fine with only a
slight flicker as the displayed freq changes. This strange occurrence is
not being displayed or observed on the K3.

On the RS-232 Port on the back of the K3, one branch of a Y-Cable
connects the K3 to the P3 via a short RS-232 Cable on the bottom P3
RS-232 Connector, and the other branch of the Y-Cable is connected to a
MicroHam MK2. The other RS-232 Port on the P3 is hooked up to the
computer comport.

On the ACC Port on the back of the K3 is another Y-Cable that connects
the K3 to the Microham MK2 and the other branch of the Y-Cable goes to
the KAT500.

Both the K3 and P3 have the latest firmware.

Both cables have been in place for over a couple years, and all of a
sudden this strange occurrence has shown up. Any one have any idea's. Tnx.

I should have mentioned that I already have even swapped out the RS-232
straight cable and Y-Cable, ACC Y-Cable from my other K3 Station and no
change in the results.

HiI may be mistaken but I think the proper cabling of the micro ham is micro ham to p3. P3 to k3 with no serial port y cable. Joe would know best. 73 Tom

That's correct ... as documented on page 19 of the K3S Owner's Manual:
"To connect a P3 Panadapter to the K3S, and optionally connect a
computer to the P3 (via RS232)".

The microHAM interface is equivalent to a computer RS-232 port when it
comes to connecting to a K3/K3S.

Thanks to Tom and Joe, they solved the problem. I remember I had moved
things around and was tidying cables up on the desk and didn't put
things back in the proper position. Another dumb move by this operator
in not properly labeling the cables. Oh well I guess it keeps the list
entertained. I must have read this solution somewhere before as this is
the first time I had the problem. Oh well live and learn.... Tnx to
everyone who offered input as to a possible solution.
