If you use a random wire in the Sony 7600GR radio and accidently short it,
can it destory the radio and/or cause damage or is it protected?

In the manual it says it has DC power but on at least two websites, it
supposely only has a "sense power" to turn antennas off and on.

I called sony customer support and they claim the jack doesn't have any DC
power in it, that it is only reception. This was said by two different
agents, but when I emailed them, they keep talking about the headphone jack
for some reason.

Will someone please settle this for me, it's like some are saying it can
short and at the same time, some are saying it can't at all. I just want to
have this darn thing settled.

Thanks in advanced.

Dear Adam,

This has been discussed many times both here and on the
http://groups.yahoo.com/group/7600GR/ group which I recommend to you
if you do not already belong.

You can attach ANY antenna to the Sony ICF-SW7600G or 'GR's antenna
jack without damaging the radio.

Period.

Of course, if the antenna is too elaborate or too long (supplies too
much signal), the set will overload. Iif you were to discharge static
electricity through the antenna, the radio could possibly be damaged
(this would apply to ANY antenna [and any receiver] and would even
apply to just touching the set in certain ways or areas while
"electrified," though such a situation would be quite rare). And
obviously you would not want to "accidentally" attach an AC adapter to
the antenna jack!

The small amount of DC voltage present at the jack is merely for
turning "on" and turning "off" the Sony AN-LP1 Active Loop Antenna.
The AN-LP1 is "on" whenever it is connected to the ICF-SW7600G/GR and
the radio is in "AM" mode. This is regardless of theposition of the AN-
LP1's own switch (used with this radio, the switch should be left in
its "off" position) or even whether the radio is tuned to the
shortwaves (where the antenna functions) or the MW/LW (where it does
not and, in fact, attenuates signals, and thus should be physically
disconnected when listening to those frequencies). It serves no other
function (it does not "power" the AN-LP1 antenna, regardless of what
has been written in PASSPORT and some other places) and does not
interfere with reception regardless of the antenna connected there. I
definitely know that a 60-foot long wire antenna (properly grounded
and protected) works very well with this radio. I have read that even
longer antennas can be successfully used but I personally cannot say
that this is so. I have used my Wellbrook ALA 330S with the Sony and
it works splendidly. And, of course, the AN-LP1 is a superb adjunct to
reception with this receiver. It is still available from dealers in
Japan and I strongly recommend it to all owners of the ICF-SW7600G/GR
radios.

Unfortunately, as you have discovered, people at Sony"s customer
"support" do not really know anything at all about shortwave radios
nor do they care. Contacting them is generally a waste of time.

However, as I stated, any reasonable antenna of any configuration can
be used with this receiver via its antenna jack

I hope this answers your question and is of help to anyone else
reading this.

Best,

Joe
