Saber alignment

Do you need a service monitor to align a Saber, or just the right RIB/cables and RSS?

You need a service monitor, as well as the RIB, RSS and cables.

has the procedure been documented, or discussed anywhere linkable on the 'net?

Procedure should be documented in the service manual at the very least, I'm sure there's a few people around here who have one in PDF format.

Thanks for the input -- I was wondering if it was something I could do myself since MSS in my area don't have Saber expertise.

Thanks,
Orlando

A service monitor is needed as it it the only way to verify proper performance, band width, frequency stability and deviation for both transmit audio and PL/DPL deviation.

You can do the job with a signal generator and deviation meter and a SINAD meter, it's just far more tedious to perform the work.

You'll also need to check receiver sensitivity, power output and spectral purity, not to mention adjacent channel rejection.

I have the necessary equipment.

these guys
http://www.repeater-builder.com/motorol ... index.html

reference this manual link:
http://www.repeater-builder.com/motorol ... 4c05-a.pdf

along with a few other manuals, in fact the systems saber service manual.

Neither of these manuals give a tune up procedure. Just generic info on diagnostics.

Know of a reference manual that actually gives detailed instrucitons?

The guys that did the page above did a fantastic job, seems odd they'd leave off such an important manual?
