I believe the TS-820 uses soldered in crystals for standard frequency control, except for the four fixed frequencies that you can install.
In relation to my earlier post, I was never suggesting that $350.00 is the average price of a used TS-830. However, with a little patience and not purchasing off the net (where prices continue to be inflated), you should be able to find a decent one near that price at a ham fest/swap meet.
