Help with Ray45 VHF weak transmission
 

I have a Ray45 VHF that receives fine but transmitted voice is
received at a weak level. When transmitting to my handheld 100 yards
away my voice can hardly be heard. I replaced the microphone element
(Raymarine actually sent me one)and it hasn't helped the situation.
Any help is appreciated.

Thanks,

Mike

Have it checked to see if it is putting out the 25 watts. On the other
hand, if it is more than two years old, dump it and get a new one. If you
have to put it in a shop, there is usually a minimum of $50 and hour to
trouble shoot it plus parts and you can get new ones for that. If you want
bells and whistles the price goes up accordingly. When I did electronics
work, it was a $50 service charge to open the case and check it out. Used to
have a lot of stuff come in and after you spend upwards of an hour checking
it out and then tell the customer it will at least three hour job plus
parts, they walk out and you are stuck with a piece of junk cluttering up
the work bench.

You need to get a "Good" Radioman to check the deviation of the
transmitter. It should be set at 4.5 Khz for Marine Radio's.
This is what sets the loudness of the transmitter in the receivers
demodulator. I suspect that it is set to low.

The mic element has a positive and negative that must be connected properly.
Did you check that when installing the new one? Other than that I have seen
the mic cords fail. I have never seen one where the dev just goes out of
adjustment.

and how many radio's have you seen in your lifetime?
I have been in Marine Elctronics better than 35 years
and have seen thousands......

Most cheapie Vhf radios use Cermet, of Electroset
mic elements, that don't switch polarities on there
own. Dev pots, however do change settings, just by
being hammered, when installed in planeing hulls
driven thru the water to fast. Yes, mic cords fail,
but very rarely do they fail, in other than a binary
mode.

Unless this fellow has a GRL License he shouldn't be
working on his radio in the first place. Replacing a
complete microphone with a plug attached is within
his preview, but opening up the case, by statute,
needs to be left to those who have the skills, and
License, required to do so. This a Marine Radio
after all.

I have been in the business for 35 years also. I am speaking specifically of
the RAY45 and I have worked on hundreds of them. The electret element has a
positive and negative side and if not reinstalled correctly it will be
destroyed.

Bruce,
I have the same radio with the same problem. I live in Chugiak and was wondering if you could help with any advice about where to take it, or if I should just get a new one.
Thanks,
Dave

any of the Radio Shops around that service Motorola Twoway Radios
will be able to test and set the deviation on your Marine Radio.
This is a simple 10 Minute proceedure.
