Not a good test as his receiver will be grossly overloaded. Could be the
result frequency drift resulting in the IF of the receiver moving off
the linear part of the discriminator. Although I still favour the idea
that the listener fell asleep. I myself have reached a semi comatose
state reading your posts, many times..

How unkind! I laughed, naturally.

Just trying to be helpful, as usual.

This one is for peaceful purposes. It belongs to a UK atmospheric radar
facility.

If your paying someone to look at you stuff, and he brings anything

because they are Dufus's and will only cost you money. /snip/

If you Google "VHF", sure enough you find entries about Viral
Hemorrhagic Fevers (VHFs) like Ebola, Dengue and Marburg. :-)

Bird Wattmeters are a trusted article no doubt.
If you come up against a strangely absorptive coax, it might just stay
absorptive on the Bird, even with the load disconnected. That should
provide a clue.

Brian W

When in doubt about a coaxial cables integrity, a Good Radioman will
ALWAYS run the test at BOTH ends of the cable, with his Bird, and see
just exactly how much power is being used heating up the cable. SWR is
meaningless if the cable is soaking up the RF Power and selfheating....

There's a well-intended tip, Bruce!
And I probably shouldn't mention how you should perk up your self-image:
always being so slow in coming forward and saying a good word about
yourself, an' all? :-)

Hi, y'all,

WIth all your wrecks and rebuilds and refits why on earth do you have
wires in your bilge??????



and our
rudder post is currently in need of repacking, sending a constant stream of
water down the bilge/limberholes,


Uhhh have you given the nut a bit of a turn??????

Why did you let it get to that condition?????????? That **** just does

IMHO the only wiring of any kind that belongs in the bilge is the
circuit for the bilge pump. * Everything else will be much happier in
a dry location, especially if there are connectors involved. *


Excellent !


I am not a big fan of Uniden electronics, preferring ICOM and Standard
for VHF radios.

I asked the two 1600 grt Ocean Masters I work with. Each have 25 years
driving boats in the oilfield. Each supported your suggestions.

One liked Standard best cause their hand helds last as long and are
cheeper than ICOM

The ABs use Icom M88 hand held with a speaker/mic. They get absolutly
abused. Dropped on decks several times daily rained on, covered in
grout and chipped clean. I spray Lysol on the my radio everytime I go
on watch. 3 ABs ahve been useing four M88s for the last 9 months with
no problmes. Except the little clip on the mic to clip onto your
shirt. butwe modified that so it works great. If their base stations
are anything like the handhelds id say buy buy buy.

It really doesnt matte how smart ya'll are You seem to froget the
obvious....
Skip is a mechanical idiot. There is no telling what FUBAR set up he
has.. Heck He probably didnt replace any of the wiring after he sunk
his boat. There was a concern that the radio want getting enough
amps.....

Who knows, he has 800 Ah of batterys and probably his battery wires
are probable nuthin but green dust inside that primary cover.

Do you really think a guy who has a rudder post that he cant set the
flow has a professionally wired VHF?

My advice.......... dont cast your pearls among swine.

Rudders and Bilges (WAS) Uniden 525 VHF and general question

Cuz that's how it gets where it needs to go. You didn't read the rest of
it, natch, cuz it didn't suit your bashing. Some folks think of bilge as
the very bottom of the boat. I didn't - if I'm incorrect, my bad. Tell me
what else to call it...

and our
rudder post is currently in need of repacking, sending a constant stream
of

Many times, over many instances.

The problem is that the post itself is corroded/pitted. That not only lets
water through, but wears on the packing.

During the wreck, we expected to have to replace the rudder, but it was
pronounced sound by several knowledgeable folks. The next major haulout, we
may indeed have to do that, unless we can find a machine shop which can
build it up and turn it back down to the proper size. Until that time, we
just have to live with it. It's time for a repack, anyway, as it's right at
3 years since I did it. Not a biggie - but the very best circumstances
still has it leaking slightly.

And, to another of your posts, we didn't sink - pretty hard to sink on a
shelf that's dry at MLW :{))

The only things which got wet were about a hundred rolls of toilet paper and
a seal-a-meal, as they were on the side on which she lay (see wreck pix in
the gallery for a better idea). No floorboards, and very little of anything
else got wet.

She towed home on her own bottom, with her own rudder (albiet a bit sticky
to starboard, due to the separated skin), and her own bilge pumps easily
kept up with the only flow, from around the core of a transducer who's
plastic mushroom had been popped off in the pounding. If it had happened to
have been bronze, we'd have had NO water in the boat...

Nice try on the slam, though :{))

About to climb on a plane tomorrow at ohdarkthirty, and all but the
injectors are removed and ready to pack. Off to defrost the freezer...
