GTX 900 as Repeater Control RX ?

d119 · Post by **d119** » Wed Dec 31, 2003 12:07 am

Planning on using a 900MHz GTX as a control recever in the 926-927MHz range. Will it work OK for this? Where are the COS and PL Indicate points in the GTX radio for interface to the controller?

Thanks!

I can't believe nobody has an answer to this one. I know somebody has access to the service manual out there, c'mon folks

A big thank you to everyone in the following thread to help shed some light on where to find COS on the GTX mobile:

Nand:

Unfortunately that image isn't working anymore, can you post it again? And is this a PL/DPL controlled connection or COS controlled?

Thanks!

Looks like it is COS only...better than nothing

I will PM Nand about the pics link being down.
