[R-390] PTO question for R-390/URR

[David C. Hallam]

I don't think there is any basic difference between the R-390 and the R-390A
PTO.  There is a difference in the cables and plugs, both power and RF.  As
I remember there is also some difference in the mounting bracket.

At one point I was looking at modifying a R-390A PTO to fit my R-390.  I
didn't think any of the problems were going to be difficult to overcome.
R-390A PTO's were both more plentiful and less expensive to buy than ones
for a R-390.  Ultimately I found a R-390 PTO at a good price and the project
stopped.
