What is with the Newport News waterworks channels? I was making a list of all the analog frequencies in VA because I live in southern MD
Like what is an S type of ch
451.100 KBI293 S 173.8 PL 3 Talkaround FM Public Works
451.250 KBI293 S 173.8 PL 4 Talkaround FM Public Works
If you look at the FCC license page, or even the RadioReference page, it shows those two as "FB2" station class. FB2 is a repeater.
It also shows 11K0F3E which is FM analog voice/data.
Unlikely it's telemetry, as that doesn't use repeaters usually. Telemetry is usually sent from a remote station to a base station and doesn't need to be repeated back out to everyone else.
The 451.100/250 are also shown as "MO" station class, which is "Mobile". Pretty standard to license the repeater frequencies that way so they can be used in talk-around mode.
The repeater input frequencies are the two that are 5MHz up, also listed as MO's.
Looks like any standard 2 channel analog repeated system to me, and based on the FCC license. Not all users follow the FCC licenses, though….
