Becker radio repair

My Becker radio stopped working recently and I'm trying to determine
what to do next. It transmits a carrier tone when the mic is keyed,
but no voice. Any speculation on what is most likely the problem? The
wires that go from the mic to the D connector on the back of the radio
test positive for continuity.

I assume the Becker USA office in Florida is the best place to have it
sent, if necessary?

Our Dittell clone had the same problem. It turned out to be a bad mic.
connection to the terminals on the radio itself. Gave them a little rub
with fine sandpaper, now all is well.

My Becker exhibited the same exact problem. Replacing the mic fixed the
problem.

My becker had the same problem. I shipped it off to the factory in FL, they
gave it a complete checkout, and returned it in just a few days. I put it
back in the glider and the problem persisted. I then fixed my bad boom mic
and all was well.

Troubleshoot with different microphones before you pull it and ship it off.

Mike,



Cleaning contacts is a good thing to do, but using any type of sandpaper
is probably not the way to go. It would be similar to trying to clean
bugs off the leading edge of your wing with a course file.. It can be
done successfully but you may get unintended consequences.



Electronic contacts usually have a few microns of gold, etc. deposited
or plated on them. It is quite easy to knock off a significant amount
of that layer of good stuff with sandpaper, even very fine grit. So use
of electronic contact cleaning solvents is the best way. Alternately,
use a pencil eraser. It has a very small amount of abrasive that can
clean the contacts nicely without doing too much damage to the contacts.




Of course, any sort of mechanical cleaning requires contacts that can be
reached by the abrasive and many of the connectors have male and female
counterparts that are inside protective housings that would preclude
mechanical cleaning. And if you can possibly get the abrasive into one
portion, the other side is left untouched. Chemical cleaning is
probably best overall.

Yep. Half the problems with radios are in the mike. Another half is due
to bad batteries. Everything else is inside the radio.

Hi.
I have a Becker AR 3201 and it don't turns on. I know the radio has an internal fuse but i don't know where. In the Installation Manual i only found the wiring connection diagram. Anybody knows where can i found maintenance and repair manual, so i can see the several components of the radio? Thank you. Best regards from Portugal.

The fuse is located next to the big coil on the board, next to where the power comes into the radio. The fuse is rated at 5 amps, and is a PICO fuse (you can buy them on eBay). Mine has 5A written on the side of the fuse. It is mounted horizontally, and spaced above the board (All other components are mounted vertically). You can replace the fuse by soldering the new one onto the legs of the old fuse -- this avoids having to remove the board, and also is less likely to damage the board.

I have not yet managed to locate a circuit diagram (schematic) for the AR3201 radio, but I will keep looking.
