[R-390] Ten Turn Stop adjustment

[R390rcvr@aol.com]

Thanks guys:

I deceided to just go ahead and try it. I forgot that the dial lock doesn't 
lock the MC knob, but it really isn't needed.
I had visually checked the stop, and there was no doubt that in this case, it 
was the stop limiting the travel.

I loosened the clamp slightly, turned the large MC gear that the clamp holds, 
until the veeder root registered between 00 and 99 when just off the detent, 
all the way to the stop. That is the position specified in the manual. 
Snugged the clamp, and I now have full range. I had never had any problems 
before with a ten turn stop either, but this poor radio has been rather 
roughly treated, and I suspect someone had slammed it against the high end of 
the stop, and it shifted slightly. I think to the casual user, they see there 
are higher numbers on the Veeder Root, and try to keep turning beyond the end 
of the normal range!

This rig has a Cosmos PTO, which I don't recall seeing in a non A. I have 
only seen Collins or Motorola PTOs. Some of the wiring for the PTO is cobbled 
together. Could you adapt a R-390A PTO to the non A.  The bracket is 
definitely for the non A.

Thanks again folks.

I will have a few more questions, as I get into it more.
