[R-390] PTO setup ?

[Tom M.]

If you don't have a freq counter you can listen for the PTO signal on another
receiver.

The signal should be at 3455 kcs when the dial is at 000 and should decrease to
2455 as you tune up. Align your dial at 000, with the PTO uncoupled listen for
it at 3455, then couple it up.
