I think that makes it fax, which isn't legal in the phone band.
It's screwy, isn't it?
Hellschreiber and Feld-Hell, which is much like what you describe, is
legal in the cw/data band but not the phone band.

Hello to all,
For me, the main problem, for Hams, of the multi-carriers modulation (OFDM...)
is that the power is drastically limited (if you want to, legitimally, keep
linear):
If you have two carriers in parallel, the mean power/max power ratio is equal
to 1/2
If you have three carriers

Hi Les!
Been a long time since we worked MT63 on 20m! The
KT2Q is a vanity, old call was AB2CJ...
Good to hear from you...

PS: Would like to eliminate the 300 baud rule, but
I don't have that kind of pull with the FCC : ).

A bigger amplifier is the solution to that. It might bring some other
amplifier technologies to the ham bands. Even with existing equipment,
if you have a 1 KW linear, that translates to 125 watts of digital which
is not bad at all. The actual addition of carriers is also phase dependent.
Anyone try WinDRM on VHF /UHF using FM simplex ?

My American friends, do you never get tired of telling each other what's
not legal under your FCC Part 97 ?

Hi Steiner,
It would be nice if Part 97 was clear and simple and we did not have
to help our fellow U.S. Radio Amateur's understand it, but
unfortunately that is not yet the case. I am in hopes that the FCC

Sir,
There are so many laws in America that NO ONE person knows them all and because
crime is so prevalent here we ALL need reminded of them. Not to mention that
there are American Amateur Radio Operators trying all kinds of NEW ideas and
some of them are NOT legal and can get them into some
Leigh,
This is the exact opposite of my understanding of Part 97 rules.
Fax is specifically what is permitted in the phone bands. Hell modes
were kind of borderline modes since they were similar to CW in some
respects.
Upon further reading of Part 97 wouldn't you consider facsimile as
I strongly recommend that any new mode specifications be placed on the
ARRL site with all the other mode specifications. Then anyone can refer
to them easily. You do not have to be an ARRL member to access this
information. It is a bit hard to find under support/regulatory
information/FCC

This is not complicated stuff. The FCC clearly prohibit encrypted
communications. Take the case of spread spectrum, the tap lengths are
specified in the rules so that it is at least in theory possible to try
a limited number of sequences to copy the transmission. The same applies
to other

Ok , I was only curious . Every time someone discover a new mode or
rediscover an old one like this MIL-STD-188-110 modem, this U.S. FCC
rules initialize the same discussion .
Don't forget the rest of the world. It is not very interesting to have
to read through a lot of text with the same old
It seems that the MIL-STD/STANAG modems frequently use a variety of
wavefoms depending upon the speed.
An example would be the STANAG 4539 suite of standardized waveforms.
They are not all the same waveforms. Starting at 75 bps data modes it
uses Walsh modulation and switches to BPSK at 150

Rod,
I have NEVER heard of any Amateur being fined by the FCC
for experimenting with a new mode...so what serious trouble?
Radio experimenting is one of the reasons our service was established!
Wouldn't that be just a bit counter-productive to be so heavy handed?
I agree with LA4VNA. We have
Steve,
You just don't get it yet, partner. As long as nobody
complains about disruptive behavior, the FCC doesn't
really care, nor do they have the manpower, to police
anything.
IMHO, be considerate of other Hams, don't try out
your new mode experiment in the middle of their
net frequency, etc.
After several years of doing RTTY via AFSK, I thought I would use the
BARTG RTTY contest this weekend to practice my FSK skills with the
new radio.
I was surprised that I was not being heard so well. I know the band
is fairly poor but stations that I could hear fairly well would not
respond to
Andy,
There should be no detectable difference between an AFSK and FSK signal on the
receiving end. Are you sure your tones were correct on FSK? The symptom you
describe sounds like you may have been transmitting reversed tones. There is
a menu setting to flip the polarity of the FSK keying in

The pk232 connection to the FSK port on the TS870s out of the box runs
