Hello again,

 

I do have two questions on the PTO of the TR7.

 

The analog scale is far away from the reality. There must be a way to align
it with the digital read-out.

I checked the service manual of the TR7 (I haven't got an operating manual)
but they don't say anything about it (or I couldn't find it).

I do see an internal "lever" which moves a plastic gear aside. As I did it,
I still see the dial-plates and PTO "screw" running. I guess this is not the
way to line these two up.

Any idea?

 

Second question:

Lately I noticed that the PTO has got a "mechanical" hysteris close to the
zero (14,000.0 / 7,000.0 MHz) If you turn down to this freq, and starts to
turn the dial the opposite side, nothing happens to the freq. Only after
200-700 Hz further is moves quickly up to the position it should. It is not
with the RV7, so I guess it's a problem on the PTO of the TR7.

Any suggestions?

 

I'm pleased to hear any advise.

 

Thanks in advance

 

73's, Evert PA2KW
