P3 bug

[k6dgw]

The subject should probably read, "Possible P3 Anomaly." "Anomaly" is a
word used extensively at NASA to indicate anything from a burned out
indicator lamp to the rocket landing pointy end down outside of Phoenix.

Test setup:
K3 #642 latest production FW
P3 latest production FW, no SVGA
KPA500
KAT500 [KPA and KAT cabled with Elecraft cables]
TX TEST [i.e. making no RF]
QSK
VOX ON
QRQ OFF

N1MM off
5 min of VVV VVV VVV ... @ 25 WPM [K3 internal keyer]
Result: No P3 recovery delays

N1MM on sending VVV VVV VVV ... @ 25 WPM for 5 min
Result: No P3 recovery delays

N1MM on
5 min of VVV VVV VVV ... @ 25 WPM [K3 internal keyer]
Result: No P3 recovery delays

N1MM on
5 min of VVV VVV VVV ... @ 25 WPM [external WinKeyUSB]
Result: No P3 Recovery delays

Apparently all P3's are not created equal and I got one of the good
ones. :-)

Well, I guess I will chime in as well.  I have spent some time this
morning trying at various speeds etc. and I cannot for the life of me
get my P3 to "hang".  I spent most of my operating time on CW and RTTY
using HRD latest beta, and DM780 and Navigator interface which has a
built in K1EL Keyer.  I tried via the software and with the paddles. To
quote from years ago in the space industry, "NTF" (no trouble found).

K3 with latest beta firmware
P3 with latest release firmware
KPA-500 with latest release firmware
KAT-500 with latest release firmware
I could not be happier with this setup.

Hi Jim,

There's been some testing done and e-mail communication off the reflector and it appears as though the culprit is the SVGA board. If those that have the problem go into the P3 sub menu and disable the SVGA board the problem should be eliminated. Test data has been passed to Wayne who has put the problem on the list of problems to be resolved.

There have been posts from others experiencing hang-ups who don't have the SVGA board. Hopefully the future fix that Elecraft produces will solve all hang-up problems.

73,
Mike K2MK
