I have a doubt regarding the firmware of the SSB module of my first K2.
I bought K2 S/N 1131 with the KNB2 and KSB2 modules. The kit was on the
shelf of the shack for quite a long time. Finally and after knowing
about the full update of the rig I decided to go for it and ordered the
new set of boards and the A to B component kit together with a new set
of matched crystals, new main CPU (2.03) and new I/O controller. The new
K2 was serial number 3279.
The question is as follows. I built the SSB board according to the last
updated manual (not the original that came with the kit) including all
the changes in the crystal filter (new capacitors and new matched
crystals). If I am not wrong the firmware release on the original SSB
board was 1.02. Although I operate almost 99% in CW I wonder if there is
any issue regarding using the old SSB firmware with the updated CPU
and I/O controller that I ordered with the upgrade from A to B. Frankly
speaking I have not noticed anything strange when using the SSB module
and the reports on the audio have been OK.
I would appreciate your feedback regarding this matter.
Many thanks in advance for your replies and best 72
Vicenç, EA3ADV
