One of my afternoon projects was a 3ft diameter loop with #16 wire and
a wide-spaced hamfest capacitor. The loop tuned on 12-30MHz and performed
as good or better than my attic dipole on 18 MHz. There was small
wire warming on 14 MHz. The antenna was on a pole (held by one hand) at the
ceiling level.
I think for 7 MHz you should be fine with #12 wire and 5-6 ft diameter.
As a side note, at the ceiling level the loop performs well only when
positioned vertically, not horizontally.

I think that's true. At the higher speeds, there's sort of a direct
connection from the ear to the fingers, and definitely the neural
connections are different when the fingers move in a pattern for writing
letters and when they go up and down in the proper places on the keyboard.
I mentioned earlier my inability to copy on paper beyond about 30
wpm...I've tried typewriter copy, and don't do quite that well...maybe 25
wpm. Part of it is that I still have to think a bit about typing. As with
learning the code in the first place, practice helps.

Well, since you want to make it personal, Jeff:
Hmmm... I didn't know the blind-ultra-fascist-hang-em-without-a-trial

Maybe you ought to study civil rights and due process before you
start calling people outlaws.

Don't be a dolt. You can't see through my eyes, you don't know how
I think, and you refuse to understand. Shoupe *says* he once ran a
pirate radio station; without other evidence, I'd have a hard time
convicting him of a crime. Do you get it, Jeff? In my eyes, I haven't
seen the evidence required to declare Shoupe a criminal. Can you see
that Jeff? I'm not the ultra-liberal you accuse me of; I consider myself
a moderate, and I try to see the big picture before I convict people.
But, no, Jeff is ready to through due process out the window and be a
complete fascist amateur radio weenie. Wonderful.
By the way, you seem to know nothing but what you've been told about
Southern California radio. I use 2m in Southern California, and it
is not the mess you would like to portray it as. Yes, there are repeaters
that are largely populated by controversial types, Yes, there are people
that break the rules, yes, in an area with 10 million people 2m is
congested in some places. However, I have 12 amateur channels programmed
in my Motorola that are *not* congested or jammed, so what the heck is
your point?
>Dana, do the criminals in your state a favor: become a judge! :)
Since you want to make it personal, Jeff, and since you are unable
to discuss things intellectually before you launch into personal
attacks, etc., chew on this:
Jeff, do the innocent people on Usenet a favor: don't become a judge!
Leave the "outlaw" rhetoric alone! Just go back to posting yet more
QRP transmitters to rec.radio.amateur.homebrew.

Well, you have checked many of the "connection" type things. It sounds
like the bad connection is inside one of the ICs or other components.
I do have one off-the-wall suggestion to try first, though. Many of the
pc boards rely on thier mounting screws to get a good ground. It is
probably worth checking these to make sure they are tight and that
the pc board is making good electrical connection. Do NOT tighten
all the screws inside those little metal cans, though! Those are
aligment screws; they do not need to be tight. :-)
A year or so ago I fixed a '940 that had a bad IC socket on the
the main microprocessor chip. That unit had developed all sorts
of flaky problems. It was a pain in the neck, but I managed to get
the old socket out and put in a new one. Do NOT remove an IC socket
as your FIRST pc-board solder experience; get some practice first.
Solder-wick or a desoldering tool makes the job a lot easier.
After that, I suggest that you purchase a can of "freeze spray", available
from most mail-order electronic distributors or from the electronics
jobber that supplies your local TV repair shop with parts.
Turn it on and let it warm up. Once it starts working fine,
use the spray to cool down major sub-assemblies, one at a time. When
the problem returns, you have found the bad board. Let it warm up
and start working again. Then, cool down the components one at a time.
When it acts up again, you have found the thermally intermittant
component.
Good luck.

Subject: Long range digital links
To: info-hams@ucsd.edu
Can any of you radio folks give me a hand with this?
I need a system capable of transmitting about 1 MegaBit per second
of digital data from anywhere on the planet. This would be a one-way
link. I'm sure this can be done, but can it be done reliably without
a satellite and lots of very fancy gear? If so, I have some questions:
How much might the equipment to do this cost?
How much would this equipment (the transmitter) weigh?
How much volume would this equipment (transmitter) occupy?
How much power would the transmitter require during operation?
How big would the antenna have to be?
If the problem is simplified to communicate within a single hemisphere,
does that make life alot easier?
Any information would be a great help!
Thanks very much!

Has anyone had any experience with the mini UHF connectors, I've seen show
up on some of the new mobile commercial radio. They look like PL259
connectors, but are about half the size. They would seem to have the same
limitations that the regular kind, but has anyone checked them to see what
impedance they give and or return loss?

The problem with putting compression fittings on 9913 is the low braid
coverage. It really has nothing at all to do with the dielectric, which
never enters into physical connections. Since it uses foil for the bulk
of it's shielding, and the braid count on 9913 is way down, you tend to
get connectors that tear off easily. Newer 9913 has more braid than older
lots so it works better. The better solution is to use the crimp connectors
designed for 9913. I like the Kings brand best. This captures the braid
between two barrels and crimps them into a solid unit. Because it engages
much more braid area than the gland, which only pinches a narrow circle of
braid, the crimp connector makes a much stronger connection. You need the
proper tooling to attach these connectors, gas pliers don't cut it, and
the tooling is expensive, but it's worth it.

We meet on Thursday nights at 0000Z on 14.265Mhz +/- 10. Tonight there
was only 8 checkins, but it's still wintertime... In the spring and summer
there's usually 10-20 checkins.
We wind up talking about nude beaches, nude resorts, natural (free)
hot springs, stuff like that. Maybe talk about some new law banning skinny-
dipping here or there, and sometimes one of the local nudist/naturist groups
succeeds in stopping some new law or ordinance from happening.
Tonight we started to formulate plans for a commemorative(sp?) QSL
card and/or certificate for Nude Recreation Week, which happens July 4-10 this
year. Yes, the picture QSL will have nude people on it, just don't expect any
"centerfolds". I'll provided details about operating times and freqs for the
"Special Event" as we decide on them.
BTW, hams in the nudist/naturist "community" have noticed a far higher
per capita ham population among nudists/naturists than in the general
population. Wonder why that is?

I was about to say "check us out sometime", but I think I'll refrain.

The small ones, like the Pyropen Jr. and the Portasol don't work
as well as a large iron. The Pyropen Sr. works fine, even in the
wind. When AC is available, however, I use a 300 watt American
