Elecraft P3 screen is flickering

P3 lower half (waterfall) is sporadicly cleared and rebuild (Slow waterfall rebuild)).

I have no idea why.

Switching waterfall off and the complete P3 screen is flickering (very fast rebuild).

Can somebody tell me how I can avoid this?

[P3 panadapter]: rs232 output working with logging software

I've got my k3s rs232/p3 port connected to the panadapter XCVR rs232 port. Panadapter PC rs232 is connected to the computer. Set the panadapter RS232 paramater to 4800 baud. The elecraft k3 utility on the computer talks to the K3S fb and connects at 4800 baud but neither my n1mm software or dxlab commander, both configured at 4800 baud, will talk to the K3. If I take the panadapter out of the chain by hooking directly to the k3s rs232/p3 port directly they both talk to it fb.
Has anyone run into a similar problem?
Thanks for help,

Re: [P3 panadapter]: rs232 output working with logging software

That's a good suggestion and it worked! I tried it at 38400 and 19200 and they both worked. When I went down to 9600 and 4800 it quite working. Unfortunately, I've got an SPE amp that has to be in the same chain of equipment and that fastest it will talk is 9600.
Funny though, that the k3s will talk to the computer software and the amp at 4800 baud if the panadapter isn't in the chain.
The panadapter will only talk to the k3s at 38400 and enforces the 38400 baud rate by automatically setting the k3s to 38400. But even when it is talking to the k3s at 38400 it lets me set its output baud rate to whatever I want. So.... the strange thing is that if I set the panadapter output to 38400 or 19200 it works fb with the computer logging software ( but not the amp cuz it won't go that high) but if I set the panadapter output to 9600 or 4800 it won't talk to the computer logging software but it will talk to the elecraft k3 utility at the slower baud rate. If I take the panadapter out of the chain the k3 and amp and computer software will all happily talk to each other at 4800 baud.
Now I'm wondering if there is such a thing as a baud rate converter that I could put inline with the amp to turn the 19200 baud rate into 4800 so it'll talk to the amp? I'm off to scour the internet.

Try setting everything to 38400 and see if that helps. The P3 needs to chit chat with the K3 and that’s best done quickly.

I haven’t tried 4800, but 38400 works here fir me.

Re: [P3 panadapter]: rs232 output working with logging software

Thanks for your help Graziano,
I'm using a cable made by Dan Tassel/SPE and I think it is the same wiring as your diagram shows.
I did finally get it working this morning. After comparing your diagram with my wiring I was looking at software port configuration more closely and I noticed that N1MM+ recommended having stop bit set to 1...... I had it set to 2. I changed it and everything started working. Also started working when I changed it in the dxlab commander software.
My takeaway is that at the faster baud rates stop bit setting is not so fussy. At the slower baud rates it IS fussy.
Thanks again,
Gary KT0A

Hi,

give a look at the attached PDF for a possibile solution.

I did this and it worked for me.
