==================================


11/8/2023 - per a google search - 'Down Island' is the towns of Edgartown + Oak Bluffs + Tisbury (aka Vineyard Haven) - (the NE end of the Island) - 'Up Island' is the towns of Chilmark + Aquinnah + West Tisbury (the west end of the Island)

Public Safety Radio Channels - 11/8/2023


the 2022 radio study lists the radio channel loads for police and fire - but does not list the radio frequencies

the fire channel load is as follows - and we will try to guess what freqs match which channels

CH 1 - "fire dispatch" - used for every day dispatch and ops - (154.1225 - DPL 115)

CH 2 - "fire tac" - (maybe 155.4375 R NAC 252 or 155.7225 R NAC 229 )

Ch 3 - "OPS ED" - cross discipline tac - ? Edgartown ? - ? police and fire ?

Ch 4 - "OPS DN" - cross discipline tac - ? Down Island ? - ? police and fire ? - ? 155.925 R ?

Ch 5 - "OPS UP" - cross discipline tac - ? Up Island ? - ? police and fire ?

Ch 6 - "FG1" - fireground 1 - (154.355 PL 114.8)

Ch 7 - "FG2" - fireground 2 - (154.415 PL 114.8)

Ch 8 - "FG3" - fireground 3 - (154.07 - PL 114.8)

Ch 9 - "FG4" - fireground 4 - (154.385 - PL 114.8)

Ch 10 - "FD OPS UP"

Ch 11 - "FD OPS DN"

Ch 12 - "FD OPS ED"

Ch 13 - VFIRE 21 - nationwide fire mutual aid -  154.28 - PL 156.7

Ch 14 - "VFIRE 22" - nationwide fire mutual aid - 154.265 - PL 156.7

Ch 15 - PAGER - 154.325 - all agencies - police and fire

Ch 16 - fire dispatch - same as Ch 1 apparently

Nov 15 2023


Dukes County might have 3 sets of 3 ops repeaters


the set up might be -


Edgartown area - Ops ED (shared police/fire) + FD Ops ED + PD Ops ED -

repeaters might be 151.265R + 155.865R + some 3rd repeater


Up Island area - Ops UP (shared police/fire) + FD Ops UP + PD Ops UP -

repeaters might be 155.40R + 151.34R + 154.7625R


Down Island Area - Ops DN (shared police/fire) + FD Ops DN + PD Ops DN

- repeaters might be 155.925R for Ops DN - and 155.895R plus some 3rd

repeater


this layout is somewhat based on the licensed locations for the repeaters


These channels can be used as tac / onscene channels - and they can be

used as backup repeaters (maybe if the backhaul system goes)


the primary day/day channels seem to be - 154.325 or 154.1125 for

paging for everyone - 156.2175R police main ("A1") - 151.4825R police

2ndary ("A2") - 155.4375R fire and ambulance main response ("B1") -

155.7225R fire and ambulance tac (first working incident) ("B2")


the only info that we can find online has the main channels and the FG

channels - but not the OPS channels?


note - this is different terminology than what California uses - from

listening to the scanner feed - 99% of all police action is on the

main police channel ("A1") - and 95% of all fire and ambulance traffic

is on the main fire/amb channel ("B1") - the Fire Tac channel ("B2")

was requested for 1 dumpster fire - the responding units were told to

switch to Fire Tac (Channel B2) - all onscene comms and all IC to

dispatcher comms seemed to be on B2 (and B2 is fully repeaterized as

are all of the other main channels) - the Ops channels are all

repeaters also - its seems that the Ops channels would only be used

when the main channels were very busy or there was a large scale

incident


it is possible that Channels A1, A2, B1, and B2 are all synchronized

simulcast with 4 or 5 repeaters running islandwide - it is possible

that the Ops channels have just 1 repeater each


note - the radios seem to be set up with 2 zones / banks - the A bank

with A channels are for police units - the B bank with B channels is

for fire and ambulance units - ( noting that A3 is the same as B3 - A4

is the same as B4 - A5 is the same channel as B5 - those 3 OPs 

channels are shared by police, fire and ambulance units apparently )
