Sony 7600GR antenna, does not turn smoothly

Hi!

I just bought myself a (used, 1yo) Sony ICF-SW7600GR from e-bay. It is
as new, but I find the antenna not turning smoothly.

Normally you extend the antenna rod and then rotate/turn it around the
base. Mostly for FM reception, since there the direction in which the
antenna points is important, but also for SW listening with the 7600GR
lying on its back or the built-in stand, to point the antenna straight
up.

With my 7600GR, rotating the antenna doesn;t go smoothly at all. It is
like the part inside the radio is jammed or has a lot of friction. It
does turn, but needs a lot of torque to do so and makes snapping
sounds while rotating in one direction (the other direction makes no
sounds but also rotates difficultly)... and the radio casing moves
lightly at the point where the antenna is in the casing.

Is this normal? What can I do about it? I do have the original
receipt, but it is not in my own name ofcourse since I bought it
second hand.

Any tips appreciated.

Not normal, though it should have enough 'friction' to keep it at any
direction you set the noise is not normal. You may wish to open the
case and look for anything that is interfering - it may be a simple
repair.
Good luck,
Howard

I wish I could help you. Actually, I have the opposite problem on my
relatively new Sony ICF-2010. The antenna swivel has gotten too loose
and it tips way too easily. Maybe the person who can solve your
problem can help me solve mine as well.

Thought og that too, but hoped to get some pointers here before that.
I have the service manual, so opening is no problem. =8-)

The antenna should be fairly taught, but not to the degree that you seem to
be describing. The antenna is a simple piece. You can try putting a drop of
fine machine oil in to its bushing. Try not to get it all over other parts.
You may have to open the set to access the bushing. Or, best yet, take the
radio to a place that services electronic equipment.

If the bushing is defective, it is most likely possible to still order a new
antenna from Sony parts, even though this is a very old model. If not, a
replacement can be easily found. These radio antennas are very standard.

The 7600 is a very good radio, and should perform very well for you.

There should be a set screw at the base of the antenna when fully extended.
Try to tighten this screw. This usually fixes this problem. If it does,
carefully remove the screw, and take care that there may be some shim
washers. They will have to go back the way that they were. Put some
lock-tight, on the threads of the screw, and put everything back again. Once
the lock-tight has dried up, the screw should not become loose again.

If this set screw is very taught, do not force it. Very carefully remove the
screw. When you take this apart, take care that there may be several shim
washers that will come out. The trick is to see if you can find more shim
washers that are very thin to add, to make the tolerance correct again. Each
of these are about 2 to 5 mils thick. You should be able to find these
types of washers from any of the distributors that sell precision machine
and tooling parts. Also, a jeweller who works on mechanical clocks, should
also have precision shim washers.

If you cannot find these washers, it is possible to get some shim stock in
copper or brass. You can then make your own shim washers, if you have the
skills for this. The idea is to tighten this up a bit. When putting back
the set screw permanently, don't forget to use some lock-tight on the
threads, or you will be tightening this screw all the time. I will loosen up
with use if there is no lock-tight.

The ICF-SW7600GR is in no way "very old", it's a current model.

BTW, I could not find any obvious way to take my SW7600G's antenna
(which rotates much too easily) apart. At least to me, it looked pretty
much like a one-way part.

I have just opened the 7600GR and removed the antenna to apply a drop
of oil (intended for a sewing machine). Now the antenna turns a little
more easy, but (holding the bushning with a vice) turning the antenna
makes the bottom part quite hot. This indicates a lot of friction...

But, I won;t have any problem with the antenna turning by itself...

He mailed me writing about a "7600", which is indeed old. My 7600GR
isn't. =8-)

Correct. I removed it from the casing this afternoon (just remove the
5 screw on the back, take the back panel off and remove the 6th screw
on the base of the antenna). The botom part of the antenna is in one
pice, so is the extendable part.
