Bottom line is they're both great rigs and they aren't THAT different.  The
differences I see are:

1. O2 uses 4-pole narrow cw filters with no extra preamp to degrade IMD.
The O1 work-around is to put 600hz 4-pole filter in 1Khz filter slot.  There
is absolutely no reason to use the 500/250 filter slots in the O1.   I've
actually thought of putting a 300hz 4-pole filter in my O1 1Khz filter slot,
since I don't need to go wider than that.

2. O2 control cpu is a bit faster;  maybe the sweep is also better (???) but
I N-E-V-E-R use the sweep (or NR); if you want sweep, go with LP-PAN via
VE7TK's if output mod

3. O2 can't run v1 firmware, which many prefer (and also has less touchy
rx/tx gain setting).

Personally, I wouldn't upgrade unless I got an O2 for a bargain price but it
would be worth hearing from folks who own both O1 and O2.
