I have currently have two radios:
Icom IC R-7000
Grundig Satellit 750

At 2258Z on Fri 5 June 2009, I was able to receive clear [with a 20-second
semi-deep fade cycle] transmissions [presumably from Kentucky] since one guy
kept speaking about someone having business in "the Bluegrass." This
transmission came through on the Grundig with the internal antenna [the
outside long wire seems almost useless]. The Icom with a discone antenna
placed 32 feet in the air was deaf.

Any suggestions on how to repair this problem or does anyone know why that
would be?

I agree Burr, though we are talking about "slightly" different
antennas. One of my three outside antennas is the Alpha Delta DX
Sloper antenna.

Four to five years ago he (ham buddy) hooked up, I guess it was his
scope, and a few other gadgets to check my six antennas....and he said
"that sloper is bad ass Gregg, if you ever want to get rid of it, let
me know." As a ham, with his extra ( I think I said that right)....I
never doubted my antennas after that. I remember I cut X amount of
lengths of wire and fanned it out so too speak underneath the length
of antenna with the measurements and seperation that he said. I had no
idea it had to be so precise,all of you that know what I'm talking
about are probably laughing at me now. ;-)

But it really is a great antenna, even all bands except one IMO -
though he said "it wasn't that bad", when you get wayyy up there it
isn't as good IMO and according to his gadgets. But if I do listen up
there (which is rarely) I just flip the switch and listen off another
antenna (either the Antron or my Yagi). I really didn't like spending
the $$$$ for it (the sloper), but looking back on it now, it was
handing over the money at the counter for superb results for eleven
years now and absolutely no headaches, other than three times I
changed the coax which is about right. It is protected (coax) and the
weather hardly gets to it and though we get the occasional ice storms
and last year for the first time in Ohio history -- the hurricane
winds, both the antenna and mast has stayed true. I would recommend it
to anyone in this group.

Yes. It has the whip on top. I built it using the directions below:

Interesting, Burr. I will look over everything in the morning. I have a
copper ground hammered about three to four feet in the ground [originally
used to ground an electrical fence] and I have both radios grounded to it
using 14 ga braided wire.

The discone is a Diamond D-130NJ with a CAB cxp1318fn-50 50' cable ...
and now I see the problem. I though I was purchasing a discone that can
listen from 25 through 1300 MHz, and the paperwork here says, "50 - 1300
Mhz." I guess I need to purchase a different antenna.

Is there a base loaded whip on top of the discone? This is how they get
the lowest octave.

RHF COMMENT:
For a "Receive Only" Antenna the elevated Discone Antenna with a Coax Cable
feed-in-line should work OK with the Icom R-7000 VHF/UHF Receiver.

The Diamond D-130J Discone Antenna "Receives" from 25 MHz to 1300 MHz * The
50 MHz note is about Transmitting.
http://www.universal-radio.com/CATAL...ants/2405.html

Getting the Discone Antenna 5~10 Feet above the Roof-Line of the House on a
Grounded Metal Mast may help to improve your overall Radio Reception.

FWIW - # 14 AWG Wire is not a very good Electrical Ground path and poor RF
Grounding. Number # 10 AWG Copper Stranded Wire is generally consider to be
the minimum Wire Size for a Radio Shack's Ground Wire.

Ground Rods an 8-Foot Copper Clad Ground Rod is recommended as 'close' to
your Radio Shack as possible with the 'shortest' Ground Wire practical.

I feel better that I purchased the right antenna, but that doesn't answer my
receiver's deafness. I have an email to AESHam Orlando to see if they have
any answers. Right now, the roof line is 13'10" high and the anchor point
for the antenna is at 31'08". I can easily place a ground wire on the mast.
The mast is 1-1/2" metal conduit. I will replace the 14 awg with 10 ga.
Right now, the copper ground rod I have is about three or four feet from the
radios [right outside the window], so the ground wire may be six feet at
most.

This is not a very good SW antenna. You need an antenna from this page
from the same vendor.

Or get yourself an antenna book like the one in the following link and
put something together yourself for less money.

A discone really is a poor antenna on CB. Any CB antenna, anything,
would be a huge improvement. I know several people with R7000's, and the
low end on them seems to deafen up as they age. Usually, by 35MHZ or so,
they are up to spec'ed sensitivity. I have an Icom discone in my attic,
as a back up antenna for my 2 Meter rig, and it's deaf as a rock on any
of my eceivers. The sloper I have up with coax that's going bad is
better on CB freqs.
