I have an XTS 3000 I'd like to add an ADP key in. I have the key that we use on APX and XTL/S series. When I input it in the software encryption portion, it shows as an invalid field.

Is ADP not compatible on the 3000s?

Correct, ADP is an Astro25 and newer feature.

Just an FYI - the "software encryption" option in XTS3000's in reference to encryption if you have a VSELP firmware loaded onto the subscriber.

If you need ENC with the ASTRO series (i.e. Astro Spectra / Astro Saber / XTS3000), you need an EMC or a UCM and a KVL with analog or IMBE (a.k.a. "P25 Conventional)

This is what I figured. No biggie, it's just a desk queen radio used for monitoring. I'll just upgrade it to a 2500 or something later on.
