REPLY:
You do make a good point about monitoring for SSB.
The big problem as I see it is the FCC 97.307 (14) (i) only authorizes four
modes for 60 meters:
2K80J3E (phone)
2K80J2D (data such as Pactor III)
60H0J2B (what they call RTTY which includes PSK31)
150HA1A (Morse CW)
So it seems that Baudot RTTY is allowed but only with a bandwidth of 60 Hz
or less. You might think that if a wideband mode such as Pactor III is
allowed,why not the much narrower Baudot RTTY?
I have no answer. For now I will stick to PSK31 on 60 meters.
