Just upgraded our Repeater from (Vertex 5000) to Motorola Quantar Analog/Digital Ham Repeater online in Northern New Jersey (Roxbury,NJ)(448.925 -141.3 NAC 293)
I am looking to Optomize the configuration, I have the Motorola Software just looking for the best configuration Details for Analog/Digital P25 operation or any other hints while I am waiting for a Fellow Ham to check the tuning on the receiver. Email or calls are always welcome...

I found that the factory squelch setting is very tight and I have mine set to 30% so the analog and digital are balanced.
I haven't really found anything else that needs to be changed from factory other than maybe dropping the PL deviation a little bit, but that that won't really affect the performance.

Other than making sure the reference oscillator is on frequency I would also check the modulation compensation setting. If the SCM has been changed or if you have any suspicion it has I would do that. It will cause the digital waveform to be all outta whack. Also be sure to check the power output and do a PA calibration if needed.

Firmware is another big one. Make sure you're running something current in both the Station Control Module, and the exciter.
Current versions are:
SCM: R020.14.048
Exciter: R020.09.018
Upgrades are available from M or by searching Google.
