 From what I understand, there is now a small self-correcting routine in 
the analog stages that involves the
3rd IF and its LO being changed slightly to keep the radio on frequency a 
little bit better.  Note we're
discussing stability and not accuracy - it's to keep the radio on the 
frequency, not to put it closer to what
should be the actual frequency the rig is using.

They are different.  They are filters being built in the UK for 
us.  They're also arranged
into a single bank rather than dual banks as used in the original 
rig.  There is probably no
difference on receiver performance on SSB - on CW with the 600 or 300 Hz 
filters
engaged maybe a slight improvement of dynamic range over the filtering 
system used in
the original Orion.  We've characterised it as 'subtle' - and it is.  The 
ARRL noted in the
Expanded Test Report for the Orion that with the 500 Hz filter engaged they 
saw a
3 to 5 dB difference from the 1 kHz filter - the idea with the new 
filtering system was
to smooth this out.

No plans to add aux monitor output.

More to come...
