Subject: ?? Need help with an external short wave radio antenna ??
To: ham-ant@ucsd.edu
I need to gather some info on building an antenna for short
wave reception? Please excuse my ignorance, I am very new at
this. Someone told me that All I need to do is connect a very
long thin wire from an adjacent tree to the house and one from
the ground and connect them into the adapter that goes into the
external antenna plug. I have some questions:
1) How long should this wire be? Is it somehow related to the
frequencies that I am interested in? What if I am interested in
more than one?
2) should the wire be shilded or unshielded?
3) what should be the gauge of the wire? The thicker the better?
4) should the wire be the meshed type or a single thread?

It does not make much difference on most of what you ask. Almost any
kind of wire will work. Get at least about 50 feet outdoors and up high.

Subject: Baluns and dipoles
To: ham-ant@ucsd.edu
I'm trying to construct dipole antenna for my FM transmitter. A few of the
books I've looked at suggest using a balun transformer between the poles.
My question. Where do I find one (or how do I make one) and is it really
necessary.
Any suggestions, (especially on what parts to buy) would be greatly
appreciated.

Subject: HELP! - Sharp PC-6200 lcd & docs
To: ham-ant@ucsd.edu
hi, mitch wa4osr here in mobile, alabama...
my sharp pc-6200 was dropped and the lcd display
was damaged... upon taking the display apart, one
of the surface mount column drivers was cracked...
rendering the display unusable... therefore,
i am in desperate need of the lcd display panel...
the part numbers on the display panel are LM64N671
and 90D13145W ... both numbers are on the panel...
my pc-6200 is actually a pc-6220, which
i think indicates that it has a 20 mb hard drive...
i bought the pc-6220 used with absolutely *NO* docs...
it has the 2400 baud internal modem... i need *ANY*
info, but especially would appreciate a copy of the
owner/operator manual... i will gladly pay for
copies/postage...
if anyone can help with a source of the lcd panel or
with the docs please email me or call me collect
at the below numbers...
thanks for any help/leads...

Subject : Re: A "shorty" 40 M mobile antenna
hi
Am interested in 20 meter mobile using a base loaded whip on the middle of the
roof of my Tauras wagon. Probably with a 64 inch whip and 3 inch spring. Do
you think there will be much ground plane component to be effective?
thanks in advance.. Bill KG7CK
