[amsat-bb] QIKCOM-2 SPoken Messages (Valid Contacts - DONE!)

Frank K5HS  (ex KR1ZAN) came up with an excellent suggestion.  Simply add
the revolving QSO number to the downlinked GRID report!

Then we need only the QSL message so that both stations can QSL each others
grid!...  So the DTMF grid will come down now as:

"Grid FM19 from WB4APR QSO number X."

A reply DTMF QSL message from someone else will be "W3ADO says QSL QSO
number _. Thanks for the contact".

Done.  And this is an elegant simple solution that fits and the CPU only has
8 bytes of program memory left! (but 12k of message memory left)...

Bob, Wb4APR

Generally a QSO is considered to be an exchange of calls and one other piece
of information - whether that's a signal report, grid square, serial number,
name, etc.
