1. "Squelch" is NEVER adjusted on any USCG guard receiver, VHF, MF, or

This applies equally to every Boat Station, Group, Sector, Activity,
Communication Station and Communication Area Master Station. Anyone

drunk will also understand the following:

i dont understand this, since operation of the squelch is part of the
training for CG radio operator on VHF

i routinely check it to ensure it's not too high.

That sounds a lot like a river-station/inland waters,

it's station sandy hook, at the mouth of NY harbor.

White-noise is guard-noise

I stand corrected about this including all boat stations.
Under the control of LANT, guard receivers make noise 24/7.


there is actually a textbook watchstanders are trained with, and this
states how to adjust the squelch. basically the process is to open it,
turn it just until the noise stops, then back it off a bit.

Neither the COMDTINST M2399 Radiotelephone Handbook (referenced) in M16120
series Communications Watchstander Qualification Guide nor COMDTINST M2300
Telecommunications Manual direct squelch as the Station Watchstander Guide
( in COMDTINST M16120, section CWS-02-01) indeed does. I just looked it up,
you are of course correct about Stations setting squelch.

In that watchstander guide, it states in part:

[Groups stand a 24-hour guard on channel-16 and are directly responsible for
all SAR cases in their AOR.]

[Watchstanders at Stations normally stand a day watch, and Stations usually
do not make initial contact with the caller unless the Group is busy or
cannot hear caller's transmission. Their normal responsibility is to
maintain direct communication with their own assets. ]

These are major distinctions between the responsibilities of a
Group/Sector/Activity and a Station, and the responsibility for
communications is the primary difference as this discussion involves. Except
for the need to train with their small boat assets, Stations would not often
be involved in CG Radiotelephone Communications at all, and are not intended
to communicate with the public, except in cases where the Group is busy or
unable. Your mileage might vary but that is the design of the Station-Group
relationship, and it does work that way in LANTAREA.
