Any Sangeans Zapped without Ext. Antenna?

Any Sangeans Zapped without Ext. Antenna?

Post by dsil.. » Sat, 19 Feb 1994 13:14:29

There have been numerous posts on this newsnet regarding zapping
Sangean FETs with static electricity when using an external antenna.
Sangean admits this can happen.

Does anyone have any experiences to report of this happening WITHOUT
USE OF AN EXTERNAL ANTENNA?

Has anyone had their radio lose sensitivity when it has been possible
to have had a static electric charge go through the radio?

Please respond on this net.

Dave

I'd imagine there is a large environmental effect to all this.  Years
of reading the net has suggested to me that people in the US have big
problems with static in the colder months when the air gets dry?  I
remember stuff in rec.audio about people zapping computers/CDplayers/
or just about anything with sensitive electronics with static.

Here in Australia static is not such a big problem...this may explain
why my sangean ATS-808 is and has been happy for quite some time.  It's
a rare day in my part of the world you have static trouble.

Regards Scott.

Suprisingly it is quite rare here in Arizona too!  The worst I have seen
was in Canada in the winter where the air was often heated 40 degrees C or
more to get to a comfortable temperature indoors.  The relative humidity
was so low that the air became an extremly good insulator as did carpet,
chairs, doors, floors etc.

I suspect that most of the frozen part of the US has the same problem.  I
try to forget what it was like myself :-)

Yes, it happened to me yesterday. I walked across a carpeted floor while
carrying my ATS-803A under my arm. When I reached the other side and touched
something, I got a static shock and the Sangean is now definately not working
properly. The sensitivity on FM is now hopeless.

Can anyone please help with the FET type and precise location on the board???
I obviously need to replace the RF pre-amp FET. Alternatively, does anyone
know how I can contact Sangean?

Many thanks

Mine, oh mine, oh mine, it happened to me, yes it did, I was sitting in my
comfy chair with my thinly veiled Sangean (RS DX-390) and the antenna
touched the lampstand which happened to be brass and well grounded
/******/ZAP/************>.
        Oh frabjous day, a warranty repair. (bought extended warranty from
RS""""""""Thinks: when DX390 is discontinued by the nice Radio Shack people
, there will still be a lot of static electricity around)

Thanks for your report, David
