SDS100/SDS200: DMR maybe RAS? Request Programming Assist

Can't speak for the XPR but the SDS100 should be able to track RAS. If you have said conventional channel (not a system) programmed into a favorites list you'll need to turn on the schools service type, it is not turned on by default
Can we safely assume you have DMR upgrade for your SDS100?
Yes DMR Upgrade and Schools for Service Type.
I'm a comms guy, it's all covered.

From what I have read, RAS makes no difference to scanners. They ignore it.

If you just enter the frequency directly from the keypad with SDS100 it will have no restrictions, Channel+frequency+Channel.
Do you hear the data signal and then it's switching to digital mode and you see DMR on the display when there's a signal from the repeater?
When they use the channel you see the color code?
If you get nothing I would guess that you have no reception at all and in analog mode you will hear nothing from that repeater.

Scanners detect a checksum error with the data frames and will treat it as a bad decode and ignore the system. The firmware in a scanner needs to detect that it is a signal with RAS and ignore the checksum handling. It will not be able to do forward error correction and will then degrade receive quality and shorten the receive range for systems using RAS.

So in other words from my XPR7550e I'm SOL if it's RAS?
You cannot use a Motorola subscriber to monitor DMR that has RAS unless you have the RAS key. Scanners are unaffected.
