[Elecraft] New KRC2 download utility issues

[Eric Swartz - WA6HHQ, Elecraft]

Hi Brendan,

A couple of questions:

1. Were you using the new V1.2 download hex files from the web page? If 
  not, and you were using earlier ones sent out by Jack, they will have 
too many records and can cause this error.

(If the earlier hex files, with too many records, were sent by a dumb 
terminal program this error was masked since the terminal program does 
not look for a handshake response from the KRC2 and always follows the 
last regular data record with a termination record that resets the KRC2.)

2. The blinking LED indicates a bad record was received by the KRC2. Did 
you try repeating the download after restarting the KRC2?

3. If you restart the KRC2 and query the version number now, what 
version do you get?

73, Eric  WA6HHQ
