What software are you using? ProScan? Butel? FreeScan? Other?
It's a P25 Standard system, or whatever it's termed in your software and the scanner. Not X2-TDMA.
Being in range really doesn't apply to simulcast distortion, in fact it can hurt when using a scanner that is not equipped to properly deal with simulcast modulation. If you are in the middle of 2 or more subsites (towers), it can cause the scanner to basically receive nothing. Assuming the programming is good, if you are able to receive the system on your pager and radio (I assume Unication G-Series and APX or some other real subscriber?), then it's probably simulcast distortion which the 996P2 does not handle well (despite what others may claim, it's well documented).
