[Elecraft] K2 Internal Keyer

[W3FPR]

Lee,
It is possible that a bit (or byte) is stuck in the EEPROM.
The cure is for a Master Reset.
BUT --- beware that will knock out all the configuration data, including 
the K2 filter settings.
I suggest you download the K2 A to B Instructions.  The first thing that 
it tells you is how to save the menu paramters for everything in the 
menu.  If you ignore that, you will have a marginally operative K2 after 
an EEINIT.  The menu for the filters and everything else will have to be 
re-entered.  THIS IS A WARNING based on much experience - I repaired 
over 2000 K2s, and several had only the problem of a hasty EEINIT.

For the K2, there is no automated way to get back to the original 
configuration, it must be done manually through the menu entries.

If you cannot resolve the problem by changing the PdL Menu entries to 
get "unstuck", then an EEINIT and restoration of the menu parameters is 
the only option.

I would also consider the firmware level may be a problem.  If you want 
to upgrade to the latest, you will have to change the wiring on the 
Control Board to that required for the KIO2 or the KPA100. If either 
options are installed, that wiring change has already been done.
