This problem (generating the 90 degree phase shift audio) is all that is
keeping me from an experiment to generate a SSB signal using a little known
technique I ran across in an old QST. It seems that a phase modulated FM
signal can be combined with amplitude modulation with the audio 90
One thing to remember. Amatuers are NOT authorized to use ACSSB above 30mhz.
Please check part 97 for the exact modes we are able to use.
heck if we were there would be tons of ACSSB repeaters already modified into
the ham band.
wonder why the fcc does not allow acssb above 30 mhz on the ham bands? seems
to me they would want to promote more efficient modes through all the ham
bands.
another interesting thing would be to see 2 meter repeaters go to 2 or 3 mhz
splits and employ some form of efficient modulation mode
I worked on an antenna problem recently on a 900Mhz spread spectrum
meter system here in Connecticut. I only spent an afternoon, but the
technology is fascinating. Two way communications from selected sites
to the meters will eventually be implemented. If the customers meter
does not have a
may be fascinating technology, but it won't be so fascinating when you are

hours.

I don't believe that comment on legality. But no,
Again, that's typical of any business. Gasoline stations have lots of
competition, yet look at the prices and how they fix pricing in any given
area.
Cable has competition from FIOS and from Dish. Same thing - they price the
same as the other guy.

oh and lets not forget the real reason they get away with what they do.
Cable, telco, and Utilities Are granted their own monopplies in their area.
no competition means they can do what ever they like to you and you have no
real recourse.

Eric,
You'd be surprised how often a radio gets bricked during a firmware upgrade.
The primary causes are impatience, where the technician disconnects the
cables prematurely because he thinks the operation is complete, and the use
of incorrect cables or flashing adapters. A radio or laptop

One comment missing from the ACSSB comment thread is that ACSSB
repeaters fill a niche that's just not needed...
If you want to do SSB on 2m/70cm, it's easy/cheap these days, and
built into tons of rigs... generally it outperforms FM repeaters
by quite a large margin across the size of most
I find nothing in Part 97 which would preclude ACSSB, as it appears to meet the
definition of phone, but I do recall some debate at the time on whether the
audio frequency inversion scheme/pilot tone was a form of
scrambling/encryption, which would have made it illegal on the ham bands. The
