Hi, y'all,

I've been active on the cruiser's net here in Abaco, and this morning one of
the neighboring boats with a radio and antenna guru aboard called me after
to say that after about a minute of continuous transmission I got faint,
though still very clear. Another station chimed into the conversation to
say they had the same result. The original boat is right next to me, so
distance or atmospheric stuff was not a factor

His opinion was either corrosion in the cable which might have an effect, or
the radio heating up from continuous tx.

As I'm heading back to the states with a pretty big to-do list shortly, for
a month, I could send it off to Uniden for a look.

Wilbur, here, isn't a great fan of this particular radio, citing other
problems which increased over time. Anyone else have this experience with
this or other radios, identified it as something other than the radio, and
have the solution?

My antenna feed for the current installation runs in our bilge, and our
rudder post is currently in need of repacking, sending a constant stream of
water down the bilge/limberholes, where I expect there's at least one
connection. While that and any other connex are professionally done, I
expect some water COULD have penetrated. I'll have a look at that, first,
but would appreciate experienced input.

Thanks, y'all

Skip, in the Bahamas for another few days before a month ashore

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. Just
about all wiring insulation develops pin hole leaks over time and salt
water intrusion will turn the finest copper into green powder in no
time at all.

I am not a big fan of Uniden electronics, preferring ICOM and Standard
for VHF radios. That said, the first step is to eliminate the
feedline and masthead antenna as possible suspects. Since we are
talking about short range, just about any kind of test antenna will
do, even a stub of wire about 18 inches long. Connect a test antenna
right at the radio and see if the problem recurs. If so you've got a
Uniden problem or a 12 volt power problem. You can eliminate power as
an issue with a voltmeter connected near the radio.

Hi, Wayne, and future viewers.

It should be noted that I have termed the path for the water which comes
from the rudder post down the Vee in the hull, well above any usual bilge,
as the bilge in this case. Any water which could enter the lazarette area
also flows on this path.

So, it's not a standing water situation, and there was no practical route to
get the antenna from the helm to the arch other than that - and, that's
where it was when we got the boat - so, that's where it is, still. It's a
Shakespeare stick so has their pigtail of whatever length it was, then a
connector to the cable to the helm. If it weren't for that, I'd probably
replace that cable at the same time I'm doing the mast one.

I'll try to find someone with a SWR meter here tomorrow morning before we
head out to our anchorage prior to going into the dock where we'll be
leaving Flying Pig, and give it a whirl.

I also have the little cable and the mast-top antenna which proved the cable
at fault in the original explorations; it will be easy for me to get a boat
buddy to listen while I read some story or something on a remote channel and
see if that cured it. That shortie, BTW, is LMR400, so should be fine for
the test. I don't expect it's got much in the way of SWR issues :{))

As to sagging power, with an 880AH bank, I doubt that's a problem, BICBW
:{)) That said, this radio has, regardless of source, often given a "low
battery" display long before I'd have expected it in terms of the "ambient"
(under load) voltage, and without transmission, so perhaps that's a radio
issue...

One of the quirks of waterlogged coax is that it can exhibit a perfect
1:1 SWR ratio while transmitting little or no power because the signal
loss is so high that nothing gets reflected back to the SWR meter.

I also have the little cable and the mast-top antenna which proved the cable

OK

Agreed but you could have a bad connection which is heating up under
load.

What Wayne said...

From what I've seen of "professional" work (unless you did it yourself and
know), it would be worth checking.

I think this whole discussion ,is just about as funny a thread ,as I
have read, in months. If you don't have the right tools, and know what
you are doing, you just "****ing into the Wind"...

Yes, there are a few "Professionals" around who don't have Clue One, and
there are some that can't afford to buy the "Correct Tools" to do the
job.

If you want a real Marine Radioman, you need to pay for his Knowledge,
Service, and his Test Equipment.... or you can stumble around and learn
it yourself, after much Trial and Error.....

SaltyDog isn't even close to being a REAL Marine Radioman..... and his
attempt to sidetrack the discussion, by introducing a Trivial, and for
all Practical Purposes, irrelevant factor into the thread, is so silly
as to show a lack of intelligence in the field.

Oh well, folks can believe what they will, but it doesn't change the
FACTS... and the issues at hand.... Wilbur, Well we all know about
Wilbur... Enough said on that front....

Accurate SWR measurements also require clear dry conditions. An
overcast day will affect the readings.

Probably a Ham's old wives' tale. Your average VSWR meter is not very
accurate, although still quite useful. This leads to all sorts of BS.
The device I use cost more than my boat..

Bull****..... I don't know where you got your learning, but you should
go back and ask for a REFUND...because you are talking thru your HAT....

I have been in the business for 40+ Years, and my Bird Wattmeter reads
the same at VHF Frequencies, in the Fog, or under then Baking Sun....
