Win500 has the following functions/features that (I think - someone can correct me if I'm wrong) aren't in any other PSR-500/600 software...
Related to monitoring/control:
* Remote (i.e. Internet) monitoring and control, as mentioned previously. Using my
TCPMux program, you can have multiple client connections to a single radio server.
* Activity logging
* Audio recording
* Internal updating of hit counts beyond radio's limit
* Internal auto-creation of new TGRP objects from Wildcard hits
Miscellaneous:
* "Notes" field for every object. Can be filled with data when downloading from RR, date/time of individual hits, and/or user text. Of course, this data isn't sent to the radio - it's within Win500 only. I primarily use it as a reference when renaming TGRPs after RR imports, where the imported "Alpha Tag" isn't descriptive enough.
* Configurable user interface (e.g. show/hide columns, re-order columns, etc.)
Things Win500 does not do that (I think) other software may do:
* Printing
The above lists aren't comprehensive comparisons.
