Dukes County
www.google.com/maps/d/edit?mid=1HIIPfzkaRIf7LnhIL75qi7PswEsQAs8&usp=sharing - zerg90 public safety map for Dukes County - created November 8, 2023 -
==================================
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
====================
Dukes County mass - radio channels - some of them
https://www.snewiki.com/wiki/index.php/Dukes_County_Fire_Departments
dukes county FG channels are listed here
but the interops channels are not listed for dukes county
no ambulance channel is listed for dukes county
if we keep digging - we might get to the bottom of this at some point
need to check zerg90 website and zerg90 freq list and google etc
=====================

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 )
