Wow! Woke up a few minutes ago and just discovered the loop antennas
group had vanished! Fortunately, it is still here and it looks like
we have a clean slate.

Yeah, quite a shock. Got a Special Notice from ElectronicDX
threatening to shut down the list because of spammers, and when I
went to see what all the fuss was about the list was gone!

Hmmm... must be a better way to handle spammers.

Anyway, I have just added a few URLs to the Links. Sites that I have
found useful for loop design. Hopefully others will add to the Links,
upload some piccies and get the Files section going again. I'll be
putting up what I can as time goes on.

Pity that we lost so much good info but no sense crying over spilt
milk. Time to "just keep on trucking".

Just uploaded the KI6GD Loop Calculator to the Files Section.
Something that I have been meaning to do for a long time. For those
unfamiliar with the program, it allows you to enter a given loop
circumference and operating frequency (as well as other parameters).
It will then calculate the Q, efficiency, bandwidth, voltage across
the resonating capacitor, ohmic loss, radiation resistance, etc, etc.
Really great for doing "what if" calculations.

It does square, octagonal and circular form loops... but it doesn't
do multi-turn loops. I'm still looking for a simple Windows-based
calculator for multi-turn loop calculation.

Enjoy!

Oh, Dude? You know thats my group? electronicdx.

Very cool. And thanks for posting in the Links, too!

RadioDXWorld says no such group.

So you renamed it? I'd thought you killed it after that email you sent
today, and then Yahoogroups said no such group.

I thought we'd lost all those excellent links and the wonderful
archives. I'm still confused about what the fuss was, this time and
the time before.

I don't see any reason to take this one down. Please place a link (if
you wish) to your loop list in the Links section.

I have this list set public, anyone can join but all new members are
moderated. I'm pretty quick about unmoderating once someone shows they
are a real person.

Do you Yahoo!?
Friends. Fun.

I appreciate the thought, but please don't make me a moderator. I
am list-owner or moderator of 15 already!

I'm very happy that you did not delete any of your yahoogroups.

So what is GCC?

Heres the group:


You see, I needed to find a wonderful solution for my friend to
get more members in his group, so I had to change the name. its
still here. I'm not that dumb to delete hard
work, even my precious antenna designs. So for now the group is
open membership
and you can be my moderator to approve membership, Its for
something that used
to be an imaginary agency, now its more like for serious hobbyist
to enjoy for years
to come. Also I have messager so I am available to talk to you.
Believe me the
group needed security for those hard to do designs for copyright
violators. Take care.

Some of you were set to No Email. I changed you to Special Notices so
everyone would get this. Please, feel free to change your settings
back to No Email. I'm the only one who can send out as a Special
Notice, and I don't typically use it much.

Here's the skinny- I'm not the moderator of the old LoopAntennas. I'm
the moderator of the new LoopAntennas.

What happened: I got ElectronicDX's special notice earlier today,
threatening to shut down the list. I sent a reply, it bounced, I tried
to go to the list, Yahoogroups said no such list!

So after thinking about it for a few hours, I started up a Group as
LoopAntennas. I figured I'll start collecting links and files and
information where I don't have to worry about it getting deleted.

I'm list-owner or moderator of 15 lists, with 5,664 members between
them. Like those, I've set this one so new members are moderated. Post
once (maybe twice, I do have a life ;')) and I'll change you to
non-moderated. If you spot a spam link or file or photo, email me off
list and I'll remove it.

Turns out ElectronicDX just changed the names of all his groups,
adding "gcc" to the title. So it's gccloopantennas, etc. If you were a
member of his lists before, you are still a member. All the files and
links and archives are still intact over there.

However, that doesn't change anything I said above. I hope no one
leaves gccloopantennas for this one, but I do hope people join this
list in addition to that one. Post good links and files, please be
specific in your description. I reserve the right to delete a link or
file if there is no description, and I will probably make some folders
and move them around a bit as soon as there is enough to make that
worth doing.

Check my other lists to see what I do with files and links areas:






Thanks from the list-owner of the new loopantennas list.

hello everyone

Scott

Well, here is my first post that makes me a member. I still don't
know what is going on with two groups, but spam happens, and I think
Yahoo sells the addresses of these groups.

I suggest a more constructive way of having two groups is to have
one group for all the shielded loop enthusiasts and another for
unshielded. I find all the shielded loop postings a bit useless -
as my designs go for maximum sensitivity - NOT noise reduction. The
moment I try to use shielded anything to construct a loop - the
sensitivity plummets. DUH - I am shielding the wire that is
supposed to pick up the signal. Now - if I use the shield of the
coax as my signal wire, I get good performance again.

Hi,

Thanks to whoever initiated the move to start over. I value the
discussions regarding loop antenna design, fabrication and use that
take place daily on this list and resent the actions of the previous
list moderator / owner to transfer my subscription without
discussion or consent to another group not at all to my liking.

Please do not hesitate to contact me off list for any additional
help or support that may be required to get this group going again.

Thanks and regards,

David Kent / k4uja

It's too bad things busted up into two groups, but I choose to stay
with this one and leave the other. Hopefully this will grow to
becoming the excellent group that it was in the past.

Please don't mess with the colors. Green on blue on red on yellow on
black is a bit hard to take. Leave it like it is, please. Thanks.

I'm hoping! qrpbear has started things off, posting in Links and
Files.

I agree, and I won't mess with the colors. I read most of my
Yahoogroups online, and I hate it when someone picks some awful low
contrast color scheme.

A little something to start off some discussion here...

Back in 1993 Rod Newkirk, W9BRD, published an article entitled "Honey
I Shrunk the Loop" in QST magazine (July, 1993). For those without
access to the article, it described a multi-turn loop antenna with a
resonating capacitor inserted at the center of each turn. The
benefits of doing so were supposedly to reduce the voltage across
each of the capacitors and to make it easier to match to 50 ohm coax.

It seems to me that the same principle could be used to construct
a "bandpass" loop that would not require retuning within a certain
band of frequencies much wider than a single-tuned loop.

Have any of you folks built one of these? If so, how well did it
perform for you?
