Bill:
I wonder how many do use an offset that low?

I suspect that Inrad chose 700 Hz as a compromise offset so that it would
work equally well with their 600 Hz offset filter and the standard Ten Tec
750 Hz offset.
Wow! Is that right? I NEVER listen with CW pitch higher
than 450 Hz and normally use 270 Hz for really weak signals. The
ability to set Orion to a pitch below 300 Hz is one of its major
benefits IMHO. No rig I'm aware of since the TS-930S has allowed
this (with the possible exception of the IC-781 which I've never
used). My ears must be strange but I would never seriously consider
any rig that forced me to use a 700 Hz pitch (sole exception being
my $205 8 ounce AT Sprint-II QRP rig with pitch fixed at 600 Hz).
