can confirm - quincy ma - fd ch1 is 483.5375R

can confirm - heard today via scanner - Quincy FD calls 483.5375R "Channel 1"

thats the honest to goodness real name of the channel

as one might expect

we can probably guess that it is in the number 1 slot on their channel
selector also

as one might expect

of course some other dispatcher might call it "main" or "primary" -
and a few FDs might call their main channel "Tac 1" or "Dispatch" or
"Ops" or "Control One" or "Red One" or "Primary 1" or "Dispatch 1" or
"Operations" or "Ops1" or "Red" or "San Jose" or "Forest Net Tone 1"
or "Forest Net Tone 2" or Forest Net Tone 16" or "Repeat" or "Repeater
1" or etc

jeez - could have many different names
