[RTTY] Fw: ARLB006 NTIA: No Objection to Additional Data Modes on60 Meters [now another FSK/AFSK thread]

[Ed Muns]

As with many things, "it depends".  FSK requires a homebrew or commercial
interface and AFSK (with respects to Uncle Bill's history lesson!) requires
proper adjustments of drive level, compression off, etc.  Which one is
"easier" depends on the individual.

There are several advantages and limitations of either transmitting method,
so which one is "best" again depends on the individual, their goals and
their particular situation.
