As far as guys checking in from their boat with no traffic that again
reinforces the operation of the net. It is also a good way for that
boater to know that he can contact the net when needed. It provides
him with a little training in communication skills also.
Does anyone get that kind of training or acknowledgement from the
Coast Guard? I think not. Practice is what makes this thing work.

Noone knows whether they can contact a CG comm center or not. Noone is
allowed to "bother" them with "no traffic" just to see if the propagation
is available or if the radios on both ends are working at the moment.

1) Boaters checking in to MMSN with no traffic, every one of them, with
this simple contact have:

2) Checked equipment to make sure it's working properly...

3) Checked propagation at the time they are monitoring to see if the
ionosphere is still operational...

4) Helped the hams monitoring the net to check propagation between THEIR
station and a maritime area they had not heard from today, just in case
their services are needed during this net time...

5) Inadvertently said, "Thank you, guys" from the boaters the doggedly
loyal ham retirees on shore are trying to serve. All they ask is for a
little check-in "thanks".

Any boater-ham should always check-in for these purposes if no other. You
have no way of knowing until it's too late if the damned CG can hear you or
not and if anyone is REALLY listening out there. "Waste of Bandwidth" my
ass.....

Hi Gary, that's all right. I was talking about an MMSN member checking
in with the net from the dock. If that's training, so be it. I don't
know if there are ever missed calls because of that chatter, but it
seems possible there would be. Training with check-in chatter could be
accomplished off-net, much like the Sunday afternoon training already
goes off-frequency for a short broadcast of interest to users of the
net. Many Hams are admittedly very skilled with break-in techniques
that keep the MMSN full of non-stop chatter with few breaks for
service, so to speak. Just my observation from over a decade of
listening to it!

So, tell us how DO you know what area you can hear on your HF net? Noone
transmits for fear of raising your ire. Can you hear Florida today?
Galveston? 100 miles out? 200? 500?

What magic on that dead HF frequency tells you the sun has exploded, again,
and communications is useless? Surely you're not depending on WWV's
propagation forecast, are you?

If we observe the two quiet periods for emergency traffic calls, wouldn't
it be better for everyone involved if you knew what boats/ships are also
your ears and eyes on the frequency, expanding your pitiful little
receiving antenna cross section by several thousand miles? "CG Net this is
WDB-6254, "Lionheart" at 32 24N, 75 12W checkin, no traffic monitoring 802
for next 2 hours." Aha! I can hear a 150W insulated backstay offshore of
Charleston on Channel 802 at this time. HE, on the other hand, will HELP
me monitor the frequency, relaying to areas I cannot hear because of
propagation, any calls that get no answers from me.

What harm have I done to Coast Guard Communications?

They USED to do it on CW, you know! It's how I learned the code when I was
10 in 1956.....(c;

This is precisely why hams "waste bandwidth", as you say.....see?

Doug (of Calista), why would you say such a thing? You just slandered
me and I expect an apology through the group, after you read back
through the times that I highly praised the MMSN and the workers in
that net. When you start inventing crap like that just because you
tire of being corrected for your consistently inaccurate statements
about the Coast Guard, your reputation goes to zero in the eyes of
honorable men.

You sir, give a bad name to hams, by lying on their behalf while you
try to defend some of the indefensible statements you have made about
the CG and their radio operations in particular. When you resorted to
slander, you stepped over the line, and that had better stop right
now.

Your ONE comment about useless checkins says volumes about your experience
as an HF communications station, CG or not.....

Coastguard stations around the world are generally blessed with
serious antenna farms and excellent professional receivers. They
are therefore well equiped to hear you if there is a signal to be
heard.


Not without a cooperating ionosphere, which hasn't been cooperating of
late.

What serious antenna farm have you been to? Their receiving antenna is a
whip! Their transmit antennas go from a whip to a conical monopole at the
10KW stations. Serious antenna farm!

Those silly hams are running 1.5KW PEP, when necessary, into an amazing
array of beam antennas both receiving and transmitting. The average Icom,
Yaesu or Kenwood receiver at any ham station has 2 or 3 HF SSB bandwidths
with digital signal processing of both IF and audio. CG had an old blue
display Commercial HF receiver, last time I went from base to base
calibrating their test equipment a few years back. What ultra-sensitive
receivers are they using today? Those ham rigs have 120 db crystal-sloped
IF skirts and .1 uV receivers. The receivers are so sensitive we have to
have an attenuator to protect them from atmospherics.

Back to the antenna problem.....

Let's say there's 50 hams in USA and Canada monitoring MMSN at noon,
tomorrow. The furthest East is in Nova Scotia. The furthest South is in
West Palm Beach. The furthest West is in Honolulu. The other 50 have
their sensitive little Yaesus listening every few hundred miles in between.
So, their "effective receiving antenna" is VERY well distributed across a
wide area of two countries, maybe even Europe and Asia at times.

CG has...well....8 to 10 whip antennas on each frequency....all right along
the COAST with nothing in between?

Which receiving system has a better chance of hearing out little backstay
transmitter, 180 miles off the Georgia coast??

PS - 22 hams KNOW they can hear me because they heard me and wrote down my
callsign on their desk pad when I did my useless chit-chat checkin.....(c;

The Coast Guard watchstander at Group Charleston thought the "Morning Dew"
distress call was a hoax. Obviously, if he'd had VHF-DF capabilities and
knew how to use it, he would have seen the display light up BRIGHTLY as the
sinking boat was only a mile and a little from Sullivan's Island Light and
3.5 miles from CG Base Charleston in the Ashley River.

Is this new stuff since Morning Dew's debacle?


10. Digital recording devices capture 100% of all incoming traffic to
USCG Group receivers.


Yes, they do! It took three TV stations calling Sen Holling's office and a
lot of political pressure to pry those recordings out of a reluctant Coast
Guard's clutches....negating any doubt about them HEARING the boy on the
Morning Dew screaming for his life.

Let's WAKE THE BOATCREW and WASTE A LITTLE OF MY TAX MONEY!!

well dont forget the CG budget was starved for years. we have one of

I offered to bring an IFR over to CG Charleston and TURN UP THE DEVIATION

them, here, you must turn your VHF volume control to maximum, especially if
the engine is running! It's been like that for years.

Talk of "deviation", I think, scares them....(c;

I'm getting ready to have a new Icom M-802


Wayne, just for information.......

That crappy PC board connector they expect you to leave out in the weather
on the AT-130 antenna tuner and the crappy CB coax pigtail SO-239 connector
CAN be eliminated at the tuner.....

The control cable pigtail is soldered to some U-shaped wire loops inside
the tuner where the book shows a screw-terminal connection. NOTE WHICH
WIRES GO TO WHICH LOOPS. Unsolder the pigtail from the loops and pull it
out of the tuner's stuffing tubes. Throw it overboard before it cripples
your HF. Cut the plastic plug off the control cable before trying to feed
it through the boat to the tuner. Makes installation MUCH neater and
easier! Run the cable through the now-empty stuffing tube and solder the
appropriate wires directly to the PC board loops you took the crappy
pigtail out of. You do NOT have to remove the PC board to accomplish this.
Just remove the cover off the tuner.

The coax is another matter......

You'd have to remove the whole tuner PC ass'y to replace the coax soldered
to the board. No fun at sea...So.... I cut the coax plug off the tuner's
RG-58 pigtail and pulled the coax back through the stuffing tube inside the
tuner. I cut the coax to a convenient length and put a new cable-mounted
SO-239 connector INSIDE the tuner, where it won't get drown in salt water.
Feed the unconnectored coax through the stuffing tube and put a PL-259
connector on it INSIDE the tuner. Use a piece of shrink tubing to seal the
coax connections and insulate the grounded connectors from touching
anything inside the tuner. Tywrap the connectors to the control cable
right where it comes in from the stuffing tube to secure it from moving
around.

ALL antenna tuner connections are now SEALED inside the environment of the
sealed tuner.....NOT LAYING OUT ON THE DECK OR IN SOME WATER-SOAKED
COMPARTMENT RUSTING AWAY!

M802 is a great radio....

Turn it on and press MODE + TX + 2 together to open its transmitter to FULL
coverage, including 150W on all the ham bands. Do it again to put it back
to marine-only transmit. (I'm afraid to leave it open when I'm not on the
boat for fear my captain will be out-of-band transmitting, probably on BBC
World Service...(c;)

MAKE SURE THE M802 TRANSCEIVER IS NOT WHERE ANY WATER CAN GET ON IT! The
fan sucks sea air into the chassis to corrode everything inside and destroy
it....part of Icom's Planned Obsolescense System, I think. Stupid
design.... I have the transceiver mounted behind the nav panel high up in
the boat above the flooding and the control panel is on the end of the
extra cable mounted in the mahogany panel right by it. Sorry we can't get
rid of the cheap crap connector on the RADIO end of the control cable.
They don't even give you EXTRA PINS for the plug in case you bend
one....how awful. Putting that plug on is the worst part of the job.

If the antenna tuner fails to tune....Unplug and plug that little white
plug into the radio several times and it will...(c;

Connecting M802 to your NMEA system needs to be done through an opto-
isolator. How stupid....a GROUNDED BNC connector, UNBALANCED, for NMEA
data to tell DSC where you are. My optoisolator is in a little box stuck
to the front of the radio....Stupid, Icom...Stupid!
