You can also do this in your PC via Total Recorder if that's an option.

Glen Clark made several such studies, including some nice color maps of all
the stations on a particular channel and how their NIF's would change.
Of course it made no difference.

Hi Maria:
The CPRV is a well-established organization that takes QSL collections and
archives them in the University of Maryland library.
Advantage: they will be preserved.
Disadvantage: only visitors to the U of M library can see them. That's not
many.
Another option would be to see if the
I'm lazy. Rather than epoxying beads together, I just buy the binocular
cores like the BN73-202 or 2873202.
The former is only $.31 in singles from Newark. It makes the best
transformer I've measured for Beverage matching - low loss, wide bandwidth.

The industry rule of thumb is that the hole has to be 1/10 the wavelength to
have any effect.
These small drainage holes (normally called weep holes) have no effect if
we're talking AM band frequencies.

Russ! You've got wires crossed. Werewolves and Send Lawyers both came
from Warren Zevon who - while almost as off the wall as Senor Zappa - ain't
the same person.

Except for the fact that they keep sucking mositure out of the air and
eventually turn into a pasty, corrosive mess that eats up any metal in the area.
Someone posted their experience with silica pacs just a few weeks ago on the
topband list and it was not a happy story.

I hope you'll repeat the test with a transformer designed for MW use. TV
splitters are rarely good for frequencies as low as the broadcast band. To
cover .5 MHZ to over 500 MHZ in one design is tough.
I'd assume your TV transformer is a 75 to 300 Ohm transformer, so it's not

Lots of connectors, boxes, IC's, R-L-C's, etc.

For short distances, go to Home Depot and get the (usually) gray plastic
conduit that is used to run outdoor wiring. Then bury your coax without
worrying about it being direct burial or not.

I'm not sure what directivity of the unwanted signals on the
coax for the most part are a non issue means. Antennas have directivity,
but signals
In a well-built system, disconnecting the coax from the matching transformer
ought to leave you with no pickup. well built means using coax that

Cable systems need very good shielding to prevent over-the-air signals and
noise from getting into the cable system. Because of that, you can easily
and cheaply buy quad shielded RG6.
It should have no leakage through the shield.
That doesn't mean the problem is totally solved. You
I wouldn't assume 1 pipe is good enough. The soil in your area has as low a
conductivity as any place in the US. If you still have problems, a second
ground pipe will cut the grounding resistance in half so is a worthwhile
effort.
One of the cheaper places for quad shield is the ebay dealer in
Garden variety RG6 runs 9 or 10 Ohms per 1000' of center conductor, so
Patrick's 75' length really ought to have about .75 Ohms of DC resistance.
I'd bet his meter is contributing to the problem.
A problem it isn't - an Ohm or two in series with his 50 Ohm input won't
produce enough loss to be
Patrick:
All the manufacturers provide data showing cable loss at a wide range of
frequencies. Some will have data at 1 MHZ and some only go down to 5 MHZ
since cable systems don't use the frequencies below 5 MHZ.
At 1 MHZ you can expect about .5 dB of loss per 100 feet - a total non
