The best answer is NO linears at all. Not gonna happen. But, in those
countries whee no linears are allowed, things seem to work quite smoothly
and operators get out and work DX better than most people here do.

Erratum:
It must be read:

For example, for MT63 where you have 64 carriers in parallel,
You transmit only 12.5 watts with a 100 watts maximum XCVR.
The same applies to the digi-sstv hamdrm/windrm modes. 30 to 60

I'm willing to bet that your FSK tones were inverted.
I own a TS-2000 and the same thing happened to me just yesterday, with a bit of
a twist. My TS-2000 had been working just fine in FSK. On Friday I installed a
new motherboard in the station computer. When I attempted to work BARTG,
Yes, absolutely. Fax is legal only in the phone band. I even confused

I don't want to hazard a guess why Hellschreiber, which faxes pictures

One other related thought.
With the recent changes to Part 97, I believe that it is now legal to
send an analog or digital image transmission in the text data portion of
the bands with signals that are no wider than 500 Hz.

Thank you, Bill! I couldn't have written it any better!
6M is a huge band, that even when it is red hot, as we
hope it is again in a few years, is very coveted by many
businesses, in addition to BPL.
The ARRL HSMM Working Group was trying to save 6M,
in addition to finding a spot to operate SS.
Chuck,
Yes, it is character assassination.
All I am saying is don't go crazy with the FCC rules.
The FCC publicly has stated the purpose of the
rules was NEVER intended to hamper technological
experimenting and other progress by Hams.
Nonetheless, that is the FIRST question many Hams
ask when
Rick,
You are not in possession of all the facts.
The HSMM was chartered to find out what it would take to do high speed data and
other modes on frequencies above HF.
The report showed what bandwidth we believe would be necessary to accomplish
the
task.

Like laws, ham radio regulatory rules are not black and white.

Generally speaking, gray areas are widely accepted in democratic
societies and have a clear connection to the notion of tolerance,

It still seems peculiar that the BOD would close down a developing
