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.
