[Elecraft] K3 command mode default k30 k31

[Don Wilhelm]

Sorry Joe,

The user said he was having a problem with the Microham MK2 - he did not 
say that he was having problems with anything else, so I figured he was 
using some Microham MK2 native commands for which the Microham MK2 was 
originate the commands.

Yes, if the commands originate in some other application, and the MK2 
simply passes them along unmodified to the K3, the same argument still 
holds, but the problem is in the application that sourced the command - 
it does not do adequate checking to assure that the K3 is in a mode 
ready to accept an extended command.  That is just not good programming, 
no matter which program it may be.

So now I may have all programmers whose code depends on unchecked 
assumptions upset with me, but so be it - I view making such assumptions 
poor programming practice.

73,
Don W3FPR
