P3 bug
Locked
 
|
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. -- 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

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. 73 Bill AE6JV On 12/29/14 at 5:47 AM, [hidden email] (Vic Rosenthal 4X6GP/K2VCO) wrote: >Sometimes the P3 'freezes up' for one to three seconds when >returning to receive condition after transmitting CW.

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... -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Mon, 2014-12-29 at 15:47 +0200, Vic Rosenthal 4X6GP/K2VCO wrote: > 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.

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.

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. 73, ...

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.

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. 73, Nate N0NB -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."

Absolutely NOT an RF issue!
It happens in TX TEST mode. On 29 Dec 2014 19:14, Mike Flowers wrote: > Likely an RF issue.

I don't have the VGA adapter on any of them.

As an aside, I have the SVGA, and do CW a LOT, and have never seen this either... -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Mon, 2014-12-29 at 09:09 -0800, Jim Brown wrote: > On Mon,12/29/2014 7:35 AM, Joe Subich, W4TV wrote: > > I have never seen this but I don't have the SVGA. > > Nor have I.

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.
