I think they probably are, but is MSP still using low band radio?
If I were running systems for an agency I would certainly keep the legacy channels I had licensed, especially since there are no licensing fees for governmental agencies. All the agencies I''ve heard about who are doing this regard the legacy channels as excellent backups, which is just playing it smart.
As one Trooper told me, "Nobody knows where the tape recorders are for the low-band." It's the primary chit-chat channel for H-3 Foxboro.
