[Elecraft] [K2] On initial Power-up, '"INFO 201" Remains

[Don Wilhelm]

Dan,

The MCU is apparently not completing the initialization process.  The 
INFO 201 should be shown only once (and not in normal operation).  It 
will be shown once after a Master Reset.  It should finish in about 30 
to 40 seconds.

The first thing to check is the soldering on the Control Board.
Reflow the solder adding a bit more (to add a bit of flux).  Use a hot 
iron (750 degF) and dwell on each connection until you see the solder 
flow out onto the solder pad and the component lead - that should take 
about 3 seconds, but if it takes up to 5, no problem.

73,
