P3 Major Problem

[Dan Lynch]

It appears my P3 has died after 9 months of flawless operation.

Yesterday I updated the firmware to windows ver 1.12.4.26 (MCU1.16).
The K3 has MCU 4.48

All worked fine for about an hour then the P3 lost everything.

The P3  black screen reads:

****FATAL ERROR***
In: ddc_set_coef ()
SPAN=0
*

The P3 Utility can not connect to the P3 either.  It attempts to connect
using different data rates but is unsuccessful.

Any ideas?

Idea:

Follow the instructions on p23 of the Rev C P3 manual (lower left) to
force a firmware load.  This involves a few steps, but they're easy to
follow.

If that doesn't work, don't despair.  If it's broke, Elecraft can fix
it.  Contact support.

This is a P3 bug that I believe was resolved in the most recent P3 firmware
version, 01.16.

You should also upgrade to the most recent P3 Utility before installing P3
firmware version 01.16.

Try power cycling the P3 just before attempting to connect the P3 Utility.

Dan,

Also check to make sure the DB9 cables have not come lose on the P3 and/or K3.
