[R-390] setting the PTO endpoints (long)

[David Wise]

I adjusted my endpoints with the PTO in the
radio.  I only removed it to remove the
endpoint cover nut; then I reinstalled it.

The key is a sawed-off diddle stick.
Plastic with metal screwdriver tip.
Short enough to finagle into position,
long enough to grip between the fingertips.
It just barely fits, but it's SO much easier.

I'll measure it and report back.

Over the last 10 years, there have been many posts about the PTO. Half dealt with the non-linear PTO, which is clearly a challenging and time-consuming task. The others have been more elementary: dealing with setting end-points.  Chuck Rippel correctly points out that setting the endpoints is probably the most important thing to do to get these receivers functioning as they were designed to operate.

Recently, I set the endpoints in my 62 Capehart PTO. What follows depends on using a counter, and avoids dropping the front panel.
