[Elecraft] MMTTY FSK

[Brett Howard]

Iain actually pointed me in the direction of using the EXTFSK .dll
interface as the FTDI interfaces don't support any speeds less than 300
bps.  EXTFSK uses the media timers to generate the baud rates at slower
speeds.  Kinda stinks that you've gotta use windows timers as that was
the main reason why I had to buy the K1EL keyer because the Windows
timing was junk...  However the K3 is already ready to rock and roll
doing things via AFSK or FSK so I can easily switch between the two
methods in the field with no trouble what-so-ever.
