153.89 - some radio test

[Peter S]

153.89 - PL 91.5 - some radio test heard at 820 AM today

first some guy sang 1 or 2 notes from the Jaws theme

then these units were called by some guy - Rescue - Charlie - Alpha - Sierra

just the dispatcher was heard - the reply were not heard

it almost sounded like 153.89 was a simplex base station connected by
maybe a UHF link to some dispatch center

??????????

maybe that was the end of a BOLO or radio test on 158.85 on Marthas
Vineyard via their "Edgartown repeater" - ????? - maybe "Rescue" was
actually "Tango"

Dukes County Sheriff CH 1 on:
158.850, 166.250, 154.010, 153.890 all PL 91.5

Tim - let me guess -

On 158.85, you just hear the dispatcher

On the other 3 freqs, you hear the dispatcher and sometimes (but not
always) the field units

I am guessing that the system is set up like this -

158.85 - simplex - base and mobiles - the real Channel 1

166.25 and 154.01 and 153.89 are all repeaters with the input being
158.85 for all of them - they function as remote receiver sites that
feed back to a voter at the Dispatch Office

lets do a followup 10 years later

the most likely scenario imho was that 153.89 was used to relay
traffic from 158.85 back to the dispatch center

the only problem would be that a portable radio on 158.85 would need
to be stronger into the remote receiver site than the signal from the
dispatcher on 158.85 into the remote receiver site - (if the portable
needed to shout over the dispatcher in an emergency situation) -
otherwise the system would work great and there would be no need for
portables to manually switch to 166.25 when in a dead spot on 158.85
