Single Sideband Suppressed Carrier (SSBSC) Video Demonstration

My guess is the x300 series won't get an SSB upgrade...

Bob,

Any chance the 8300 gets the SSB mode? 

The only Orban processors capable of running SSB are the 5500, 5518 (which is a stand-alone stereo generator). and 8600. (Of course, the 8500 can run SSB after being upgraded to an 8600 with the available upgrade kit.)

The other Orban FM processors don't have enough spare DSP power to implement the SSB generator. The 5518 will get the upgrade fairly soon.

Very interesting article in July 4 Radio World on SSBSC.Believers and non-believers. Smart move on Mr. Orban to incorporate this in the mid-level priced 5500. Have the feeling alot of demo's will be going out.The benefit of SSBSC without paying a high end price.Brillant...

Wheatstone is touting the "Automatic Multipath Controller" in their Vorsis processors as an alternative to SSBSC:

Their description of how it works sounds a lot like some processing tricks that were used as far back as the '80s, such as stereo enhancement with width limiting which restricts L-R to no more than 70% of L+R. That way, the separation of "wide stereo" mixes is reduced (thus improving mono loudness and reducing multipath) while the stereo imaging of more modern recordings is preserved or even improved.

I tried this concept out a number of years ago, and it did not make much difference with regards to multipath.

Same can be said with those experimenting with SSB as well.Seemed it helped with multipath in some locations and not others.The jury is still out on this.Multipath is a strange animal..

I put that update on my 5500... I am curious as to why the 8300 can't do it.  Doesn't the 8300 have a more powerful DSP than the 5500?

Out of curiosity, what equipment and radios did you use to test out the system?

I’m pretty sure the 8300 has been discontinued.  I believe the 5500 has replaced the 2300, 5300, and 8300.

Correct. The current Orban FM processors are the 5500, 8500, and 8600, plus the 5518 stereo encoder (which only has overshoot limiting).
