G.E. Master II Repeater Interface Problem

T.E. Butler
 

Hi Fellow Hams,
I just acquired a Master II Repeater and interfacing a Cat 300 DX
controller to it. I have everything done except I wish to use the
RUS line for COR input. The RUS line goes high for a split second till
the exciter keys and then goes low. There must be another place to pick
up RUS that will stay high as long as the receiver is unsqelched. I am
hoping that someone knows of this location. Using the RUS as COR is in
light of having mobil flutter problems on a previous converted Master II
mobile.
Another thing that I need is where to pick up a CTCSS output from the
factory G.E. pl board. I need to go high on a line when P.L. is
present. I didn't find anywhere on the backplane that gave me this.
Any help would be apperciated very much. Thanks, Tom Butler, N5KWN..

Try CAS. Should work much better.

You can go to scom's web page and look under technical ah heck with it I will
attach a file on how to interface a 7 k to a mastr II base from scom home page it
is in word format. I too am getting ready to do my first base station interface
and this info came in real handy. on the mobile flutter there is a capacitor
that you can remove on the ifas board to defeat the short squelch tail and force
it to 200 milliseconds just by removing this cap.
