[Elecraft] Age of K2?

[Don Wilhelm]

Mike,

I recently did some investigation of my repair records, and discovered 
that a K2 serial number of 69xx dates back to 2011 or 2012.
Never fear, that serial number is fully up to date with all mods that 
are available for the K2.
It may have MCU 2.04P while the newest is 2.04r, but the only difference 
between those two firmware releases is that 2.04r locks the sidetone 
source at U8-4.  MCU 2.04P allows the sidetone source to be switched 
between U6-25 and U8-4 in support of very old K2s.  The number of 
support calls and emails saying "I have lost my sidetone" prompted 
Elecraft to make that change.

So if you have MCU 2.04P and lose your sidetone, just check the setting 
of the sidetone source - it is easy to change, go to the STL menu and 
edit the parameter - tap the DISPLAY button to toggle the sidetone 
source.  You could also update the firmware to 2.04r (E610002 - FWK2MCU)

73,
Don W3FPR
