Of course its a problem in MFSK-16 to transmit a file...perhaps cutting and
pasting a text into the transmit window would work.
But when we start comparing modes, we need to have a standard text to transmit.
Back Jan 1990, I discovered that the government had a standard text used for
evaluation...it was 40K. You don't have to use such a large file; but we DO
need a standard length file for proper evaluation testing.
