P25 Out of Band Limitations

Unfortunately for those wishing to use P25 in the ham bands, there is a firmware restriction for the UHF-R and VHF-K bandsplit radios which prevents the vocon from modulating P25 below 450 and 148 MHz, respectively. This firmware limitation can be worked around by directly editing the codeplug partition, but unfortunately this requires tools even more advanced than standard Astro25 Depot.
