They should be transmitting digitally but I don't know if anything is available or not for this application. Seems like it should be. So much old technology.

Not sure what "huh?" means but if you were not aware, analog radio transmissions such as this are slowly being phased out of existence and being replaced with narrow band digital formats such as DMR, P25, NXDN, ATSC-DTV, etc. Public service, BYU, ham radio, Broadcast TV, sattelite radio, etc. have switched over. These Comtek systems are bandwidth hogs.
It was previously mentioned that a receiver with DSP was useful in filtering out noise for this application and I just added that digital transmissions would further enhance the experience or even reduce the need for DSP.

Ok, so you were talking about a future direction rather than what's happening now.

The main drive for going digital has been to find space for cell phones. The latest causality being C-band satellite making way for 5G. However, I don't think there's much interest in 72 MHz.
