[Elecraft] 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?
