why does my reception go to hell AT NIGHT ???
 
Go to a park away from all the "noise". Dimmers, fluorescent lights,
AC lines. and so many things we don't know could affect
reception.........Good Luck........Dave, again-----------PS. be
thankful your in LA it's snow here in St. Louis.

thru it on 5950, but generally this is all i hear.

That's what happens to me when someone in a neighboring apartment is watching cable television.

i went out to the edge of our yard and reception was fine-- the
bzzzzzzhmmmmmmmmm decreased as distance from the house increased.

can this be fixed with an external antenna mounted sufficiently away
from the house, but with an ultra-shielded lead-in cable to the house?

Yes . . .

take your radio outside, truck it around in the yard, find the best
reception area,

put up an antenna there.

then put in a nice shielded co-ax into your house, shielding the whole
thing.

Duct tape is actually a fairly good shield, BTW . ..

I convinced my better half of that some months ago. She wasn't impressed.

Perhaps you meant the aluminium foil stuff which goes by some other name?

why the heck is my reception going to hell AT NIGHT ??? have eton e1--
random wire antenna out the window, i hold bare copper end to center of
pal jack and switch on external antenna (i know i know-- better antenna
and proper connector are on the way).

BUT, I get decent reception in the late afternoon via this method.
HOWEVER, at night, this terrible BZZZZZZZZZHHHMMMMMMMMMMMMMM buzz is
all over the damn dial. Omnipresent. Occasionally radio taiwan breaks

please help!

thanks.



Could be a nearby transformer going sour when the sun goes down. I had
one about a half mile away from me that put out all kinds of hash when
the sun went down, or when it got below 60 degrees or so. It wasn't
horrible when it was warmer out, but when it got cold, wow!


Lightning took care of it one night, after about 2 years of the local
power company telling me "It's on the list".

How did you figure out that transformer was the cause? I have a very
similar problem--horrible RFI when it's _cold_ outside. I figured it
must be a neighbors heater, but now you've got me thinking.
