What do you mean by a barrel connector? A UHF type bulkhead connector?
What do you do with the center conductor? Just shove it into where the
center pin would go?
Can this be done with N connectors?

James, there are indeed evil spirits in the air, and some of them
will tell you to ground your rig if you want to get out. Don't
listen to them.
Your RF belongs up in the air where it can radiate like the
Chief Op intended, not run through lossy earth like your neighbors
would prefer. RF energy is expensive to generate - treat it like
the precious thing it is. Never allow it to flow through anything
that soaks up power like plain 'ol dirt.
The only two reasons you need to "ground" your rig are for safety,
meaning 60 Hz, not RF, and for lightning protection. DO heed the
advice of those who know about those things, but keep your RF away
from anything that dissipates instead of radiates and the DX will
come your way.

Never ground to the electrical system of your house, will cause you
more grief than its worth. A good ground should be as short as
possible to an 8 foot ground rod, in your case that will be next
to impossible. MFJ does make an artificial ground that will give
you an adequate ground for your station. Keep the leads away from
prying hands or you can get a good burn from them. This is one MFJ
product that will work for you. For more details on a good ground
pick up a copy of the Amateur Handbook and go from there.

That's the second time this question has been asked this week in this news
group!
One solution is to cut a few quarter-wavelengths of wire, one for each of
your favourite bands, and connect them all together at one end. Connect
that end to the chassis of the receiver. Then drape the free ends around
room - no need to keep them straight. You could tack them to the skirting
boards and around doorframes, or simply spread them around under the
carpet.
Example lengths:
7 MHz about 33'
10 MHz about 23'
14 MHz about 16'6"
21 MHz about 11'6"
28 MHz about 8'3"
Hope this helps.

Subject: Help identifying some SMT devices
Can only answer part of your question: Why all the resistors in
parallel? Since parts have become so cheap and labor so expensive,
manufacturers have found it more expedient to parallel or series
components to create the value desired rather than spend the effort
to stock many different part numbers. Two 10Ks = either a 5K or a
20K with no extra documentation at all. Make it three or four or
more and the savings get even larger. Granted, the purists will
complain about reliability when using more parts, but the reliability
of components run at low power these days is so much better than the
old days that it doesn't really matter.
Hope this helps.

There are boatloads of excellent morse tutors for most types of computer.
Not sure where you are, but if you're in the UK try the BBS below where
you'll find dozens of tutors for the PC, a couple for the Amiga, one for
the Mac and one for the ST - all free and downloadable on the first call.
If you're outside the UK, add the access code, then 44, and drop the 0

Subject: Re: "How far" does 1 milliwat (and 1 watt) go?
Back when I actually found time to get on the air (I DID get to play in the
/125 event -- a blast!!!), I was using 250 milliwatts to get my Worked All
States award. One day I was chatting with a ham in Florida (sure wish I
remembered his call!), who was running 100 watts. When he heard I was 250
mW, he decided to drop power, too.
He cut back to 50 watts, whereupon I told him I couldn't tell the
difference. He then cut back to 10 watts, then 5 watts, then one watt. At
the latter I told him he was down to only 10 dB over S9! He then came back
to me at RST 579 and said that he couldn't even see his power meter moving.
I told him he was still Q5.
Then he told me to wait. About 15 seconds later he was in there, as weak as
I could imagine. I copied most of what he had to say, but told him he did
have to increase the power as he was only about Q3 and I was having a real
hard time. He came back with the CW HI HI, and told me that I had just
copied 5 watts into his dummy load.
I think we both learned something that day. :-)

You don't even need Arecebo. In the book FIRST CONTACT, author/hams
Cullers and Alschuler describe an amateur SETI station composed of a
3-4 meter dish, an ICOM 7000, a GaAs FET amplifier providing a system
noise temperature of about 100k. With a digitizer board and a computer
software capable of Fourier Transform spectrum analysis you would have
a competent system.
The authors recommended using Voyager II (then at about 30 A.U. from
Earth) broadcasting at 20 watts on 8 GHz as a test target! I wonder if
anyone actually did this?
Now when someone actually picks up ETI, that will probably set a few
interesting records. ;@} And who said microwave wasn't good for DX? ;@}

Subject: Re: 1/2" CATV hardline connectors?
>
> ...<many techniques for terminating hardline discussed>...
>
The only method which worked for me was to use an N male
connector intended for RG-8 or RG-214:
1. Using a 1/2" drill, enlarge the I.D. of the clamp nut (the thing
that normally slips over the jacketed coax and threads into the
back of the connector) to 0.500" (for 1/2" hardline).
2. Buy a 1/2" compression ring from the hardware store and, using
some precise tool like a Dremel with cutoff wheel, cut the ring
diagonally. This cut will allow reasonable force to compress the ring
onto the aluminum hardline without too much deformation.
3. Prepare the hardline by stripping the outer shield and foam back
1/8" from the center conductor.
4. Patiently file down the center conductor's diameter until it will
permit the N connector's center pin to be soldered on. Solder it.
5. Put it all together.
This technique gives good electrical performance but will not
grip the hardline mechanically very well. Make sure the weight
of the hardline is borne by something other than the connector.
Also, aluminum and copper/brass/bronze get along poorly (they
corrode each other). Be sure to sand and clean all surfaces which
will contact dissimilar metals, and lightly coat these surfaces
with silicone grease or such (the hardware store has this sort of
goop for people with aluminum wire in their houses). Some sort
of butyrate weather coating (such as ScotchKote) on the outside
will also help keep moisture out, as will self-vulcanizing
rubber tape (such as Scotch 23).
