Just another repeat of yesterday for me so far.

Hi dxAce

It looks like I can't get LP down here. At least not since I've been
trying.
I'm no lame even though I'm only doing "our thing" for 8 months. But,
I've
learned a great deal and have good equipment. I guess I have to catch
him
under the best conditions.

Hey, I pick up plenty of good DX stations down here in Florida but no
luck
for Lucky so far with LP.


Hang in there, you'll catch the Poacher.

Should be up at 1200 on 16084, 15682 and 14487.


Heard here on all three frequencies with the 'Poacher Tune', weak.

Hey Lucky,
I'm sure you've mentioned it ...but I missed it. What receiver and what type of
antenna are you using.

I heard LP on two of the three incorrect freqs yesterday on a Hammarlund 129X
with a 600ft. tract of wire and on my modded DX-394 on an Alpha Delta sloper
roughly 60 ft. high.

Keep trying, you'll hear it. If I can hear LP on the wrong freqs, I'm sure you
can hear them on the correct ones. ;-)

Hi

Ok right now I'm using my JRC NRD-525 with a 35 Ft dipole and a 4:1 Current
balun coupled with a MFJ-959 pre-amp/tuner. I don't use the tuner that
often. As you know it amps the noise too along with the signal so I use only
it when absolutely neccessary. I'm on the 23rd floor of a building so I get
good signals.

That's your problem... you're using a dipole. A dipole is for use on a very
narrow range of frequencies. Now, using the tuner, you might get a better match
to the receiver.

My suggestion would be to use a single wire, and match it with a transformer. I
think you might get better broadband performance from that.

However, you may be somewhat limited being on a 23rd floor.

That's not so lucky, no pun intended.

Yes I am limited to the type of ant I use on the terrace. But, I seem to get
less noise using the balun. But being on the 23rd floor I have no real
obstructions. So you think I should go a random single wire? What kind of
transformer do you mean? I research I did on ants say you need 4 leads for a
blaun to work. What can add to a single wire?

Thanks for the tip.

pardon the intrude! first- Ace is one of the posters i
would ask an antenna Q of. he has helped myself, and many
others on this list. second- have you thought of a loop?
i am one of the fortunate people to aquire an Ed-loop,
("Torus-Tuner Loop") from Ed before he died. i'm hoping
someone else will pick up where he left off. i got the
L P on the Edloop with a sat800 just this last sat. i also
use the sony loop in the car when on the road. it's a
little odd to see the loop in the pass-window, but it works.
J.A. uses a wellbrook loop in his apt. he says it works great.
put out a few Q here, or google it and see what you find.
how bout it- RHF ? you hang in the antenna/yahoo gps, what
have you got to say??? ymmv- just my .02...

DRIFTER,

YES - Since "LUCKY" is 23 Floors Up-in-the-Sky with a Balcony,
he can take his MFJ-959 Pre-Selector and build a single turn

You can wind up a transformer so that you only need 3 leads, rather than
grounding it at the feedpoint.

This is the same concept that the RF Systems Magnetic Longwire Balun (MLB) uses.

It then uses your receiver ground as an aid in completing the path.

Here, I'm using 10:1 homebrew matching transformers and they are grounded at the
feedpoint, but as I've said, there is a way to get around that if it is not
practical or feasible.

Here are some matching transformer/balun articles:

LUCKY,

Forget the Dipole ETC.

Since your are up 23 Floors (10-12Ft X 23 = 230-276 Feet)

Vertical "Drop" Antenna # 1.
- Buy 100-200 Feet of TV 300 Ohm Twin Lead.
- Take the Far-End and 'bare' the Wires, then Twist the ends together.
- Attach a 8 Ounce Fishing Weight to the Far-End.
- Take the Near-End and 'bare' the Wires, then insert/connect
them to the Antenna and Ground Terminals for your Receiver.
- Lower the TV Twin Lead out the Window for your antenna.

Vertical "Drop" Antenna # 2.
- Buy 100-200 Feet of TV 300 Ohm Twin Lead.
- Take the Far-End and 'bare' the Wires, then Twist the ends together.
- Attach a 8 Ounce Fishing Weight to the Far-End.
- Take the Near-End and 'bare' the Wires, then connect them to
the 300 Ohm-End of a TV 300 Ohm to 75 Ohm Matching Transformer.
- Connect the 75 Ohm-End to a 6-25 Foot piece of TV 75 Ohm Coax
Cable. {Enough Coax Cable to go from the Window to the Radio.)
- Buy a "F" to SO-239 Adapter (RadioShack Catalog # 278-258)
to 'connect' the TV Coax Cable to the So-239 Jack on the Radio.
- Lower the TV Twin Lead out the Window for your antenna.

NOTE: Make sure that the Fishing Weight is between Floors
and not hitting (breaking) anyones windows :-{

Probably a bad way to go as that antenna will be going right past all those floors
full of interference.

If he has access to the roof he'd be much better off with a horizontal antenna up
there.
