Howard,
Don't know if you got a reply on this. The optional SO-3 TCXO is a
temperature controlled crystal oscillator to improve frequency
stability. This was standard on the 2000, and I would guess on the
990, but not on the 590 or 480.
I am sure that most of the 590's on the air don't have this installed.
It is a $120 option. You need to remove a pcp board, solder it in,
change a jumper, and do some alignment with the included tool. In
comparison, the VGS-1 speech board is just a plug in module.
If you think you need it, go for it. I've had my 590 just over 2 years,
no TCXO and no problems. I know some of the guys who are big on psk
and other such modes find it helpful, but again I think the vast
majority of units out there don't have it.n
73, Steve KW3A.
