P3 bug

Vic Rosenthal
I've seen this mentioned by others, but I don't think I've heard an
official response.

Sometimes the P3 'freezes up' for one to three seconds when returning to
receive condition after transmitting CW. It doesn't happen every time,
but enough to be bothersome, especially in a fast pileup. It is not
caused by RF, because it happens in TX TEST mode.

I have the VGA adapter, if that is related, although the freeze occurs
on the P3 screen as well.

To reproduce the problem, switch to TX TEST mode, and repeatedly send
VVV at 25 wpm. The P3 will usually come back immediately after each
group, but every few times it will stay frozen for a few seconds.

I have seen the same behavior as well. I'm away from my K3/P3,
so I can't test it, but I think I have seen the freeze in AFSK A
and SSB modes as well. I also have the SVGA installed in my P3.

The behavior reminds me of the way the Apple ][ would go "out to
lunch" every once in a while while the Basic interpreter ran
garbage collection. If the P3 or SVGA is programmed in a garbage
collected language, that might be the problem.

In reply to this post by Vic Rosenthal
Hi Vic,

If I remember correctly, there was a discussion here a few months ago,
(which I can not locate in the archives for some reason), dealing with
this behavior...  I think it had something to do with telling the K3 to
key down in two different ways...  Something along the lines of using
PTT with your DTR/RTS line, and/or using VOX, etc.  

Something along that line...  I searched the archives but did not locate
the post which covered this...  I am pretty sure the words "race
condition" were used in the post, so I searched the archive using that
as the search term, but alas, nothing...  

Hopefully this will trigger someone with a better memory than I...

Re: P3 bug

I remember that discussion. I am pretty sure it was about a different
problem. Anyway I am using VOX (er, QSK) with no connection to PTT.

In reply to this post by Bill Frantz

I have never seen this but I don't have the SVGA.

The P3 "mutes" in response to the TX flag in the IF; info or perhaps
in response to the TX; "get."  I would guess the freeze is due to
missed or corrupted data between the K3 and P3 ... perhaps due to
additional processing/data to support the SVGA.

Re: P3 bug

Mike K2MK
In reply to this post by Vic Rosenthal
Hi Vic,

I have brought this up on the reflector. I have not given test mode a try but I will. It was strongly suggested to me that it was RF related but the problem crops up to the same degree at high power and running about 30 watts barefoot. I have also loaded up cables with ferrite clamp-ons and the problem persists to the same degree. Always intermittent and unpredictable.

I also have the VGA adapter and the problem is visible on both the external monitor and the P3 screen. I have not tried removing he SVGA board to see if the problem persists.

It was extremely annoying when I was operating as a W1AW/2 station working RTTY split. I depended on the P3 to direct my focus to stations in the clear. It repeatedly let me down.

73,
Mike K2MK

Likely an RF issue.  Noticed this a few times, but not since implementing K9YC's equipment bonding instructions.  

Thanks for those excellent tips, Jim!

I saw it last night for the first time on 160m and I was running the
amp.  I saw this happen for more than a "few seconds" and at several
random intervals.

I currently have firmware 1.29 installed and I could put 1.09 back into
it.  I don't recall seeing this happen with 1.09 or, at least, the
recovery of the P3 was much faster.

I have a plain P3 with no SVGA board installed.

Absolutely NOT an RF issue!

It happens in TX TEST mode.

To whoever suggested RF later in this thread, if it happens in TX TEST then
it's not RF. ;)

As an additional data point, I run three K3/P3s during RTTY contests in FSK
D mode, and I have never seen this. I don't have the VGA adapter on any of
them.

Hope this helps - 73 - jeff wk6i

P3 Bug

Edward A. Dauer
In reply to this post by Vic Rosenthal
I don¹t think it¹s in the SVGA, or at least not exclusively so.  I have
the identical experience with a P3 that doesn¹t have the SGVA option
installed.  Likewise I don¹t think it¹s a logging program hanging up a
port - I don¹t use a logging program - in fact I have no computer
connections to the rig at all other than briefly during firmware loads or
configurations.  Oddly, the hangups began for me just after I updated the
F/W in both the K3 and P3 about six weeks ago (I am not at the rig now and
so don¹t have the version numbers handy).  Never happened before then.
