Race comms overview

cities and towns along route handle police/fire/ems comms on local channels

mutual aid comms can be on bapern channels and fire district 13 and 14 channels and bama 453.10r and on interops TGs on the 2 or 3 state TRS

utac and vtac and itac and fed interops channels might also be in use for patching and special units

media might have special channels

race admins are on a business TRS iirc

hams might serve as backup comms

1135 am 453.10 R

"Boston EMS to Cataldo"

"Cataldo answering"

do you have an ambulance available for a call at East Boston Health Center?

we are already enroute

except it turns out it was 2 different calls and Cataldo Ambulance Service does not have a 2nd unit nearby

1144 am - 'Boston EMS to BAMA' - "seeking a bls unit for another call at East Boston Neighborhood Health Center" - (not sure if this is a 3rd call or not)

470.5625 R / BAP 4 seems to be patched to 460.35 R / BPD Ch 1

nobody is saying much but they are getting kerchunked randomly at the same time

1144 am - Jake Charlie 1 requested a service unit from 14 to 2017 Comm Ave (that is the Brighton section of Boston and the Marathon goes along Comm Ave there)

they have been patching these 2 channels for the Marathon for the last ?7? years - perhaps so they get a larger footprint than using just 460.35 R alone - 460.35 R might cover out to Rte 128 but 470.5625 R might cover out to Rte 495

no messages on these 2 channels from 1145 am to noon - very quiet

noon - echoey message from some dispatcher - "Radio 9921 emergency button - you all set?" - no reply - no followup

1202 pm - radio message from field unit was heard on 460.35 R before being heard on 470.5625 R - maybe a 1/10 second delay - is that due to my radios or their patch? - probably their patch - my 2 radio are identical and sitting next to each other
