basically as the title states. i have never heard of
ACSSB outside of 220-222 mhz.
There was quite a bit of hype about it in the 80's and
90's, I recall seeing mention of it in various Handbooks
and Magazines.
Seems to me ACSSB was a good idea and was curious as to
why the ham community has not picked up on it for mobile
HF SSB use.
Simple
Cost of the radio and what mfgr is going to stick their
necks out trying to make a dollar on an unknown format
when known modulation schemes are already on the scene.
In short, how practical is it? There might be a case to
include it as one of a selection of available modes in
newer software defined radios... but don't look for it
anytime soon.
seems to me having the benefits of SSB without the hassle
of messing with a Clarifier all the time has it's advantages
in a mobile environment.
It might... but Hams and CB'ers don't mind cranking the
knobs. If you wanted hands off operation, FM is there and
much more practical.... translation cheap to buy and
use.
i know that the likely reason is NBFM and P25 for the demise
of ACSSB, but as stated above seems to me it would be at
home in the HF spectrum.
It's not hard to insert and detect the carrier in HF operation...
but most of the newer HF Rigs have great frequency stability
so once you adjust your RIT knob... you shouldn't have to go
back.
I know i am going to get flamed for this, but i think ACSSB
would make a great replacement for standard ssb in the 11
Meter Market.
Too many radios already out there over a very long time span
so you're not going to see any major changes on 11 Meters and
it will remain a train-wreck for the most part. Rural Areas
are not so bad when band conditions are favorable.
it would also allow the use of CTCSS on HF using a more
efficient mode than FM. imagine having ACSSB 10 meter
repeaters instead of FM.
In real world application... doesn't work so well. Again ACSB
is another variant of AM and horribly suffers from noise
issues, which is one of the major reasons the 220/222 MHz
trunking farted and went away.
RIP Securicor, Intek, LMS (Linear Modulation Systems), SEA - ACSB
and Uniden ACSB.
