I'll add my voice to that as well. Please add that capability to increase

This works! 4 shots of !66; did the trick! Hope the Elecraft team can add

In my experience magnetic loops and QRP are incompatible UNLESS we are at a
high sunspot situation. Lots of articles have been written over the years and
a good one was in QST using a trombone-shaped tubing for the tuning capacitor
with PTFE between the parts. Use minimum 22mm copper tube and
I'll certainly second David's, G3UNA, comments about using a wire for
transmitting.
Loops can be very effective for receiving though, as you noted. Any decent
receiver (like the K2) has plenty of excess gain to make up for the losses
in the loop itself, and they do tend to pick up less noise. Wit
Hi Stan,
I've built a number of mag loops.
I've used aluminum tubing, copper, and hard-line coax as the main
sections.
I purchased a dead AEA HI-Q loop unit on ebay for cheap years ago and
pulled the capacitor off it.
The ERP is off-course compromised compared to a dipole.
However, its advantages
I have an old AEA loop in my garage attic. It functions very
effectively. The bandwidth on 20 is no more than 10Khz or less. But
signal reports and reception are only slightly lower than my full-size
dipoles. When you get the feel for using it you can retune in seconds
using just your ear an
I have just published the details of a little portable QRP magnetic loop I
made, on my website: http://www.g4ilo.com/wonder-loop.html. I compared it
with the MFJ magnetic loop I have in my attic and I am very pleased with it.

I'd like to be clear when I wrote earlier that a small transmitting loop is
very inefficient.
I didn't mean they don't work, only that they only radiate a small part of
the RF applied to them compared to a larger antenna.
Consider a typical mobile "whip" antenna. They're terribly inefficient to
According to the loop calculators available online at various sites the
efficiency varies as a function of a number of parameters but making one for
20 or 30M at 90%+ efficiency is certainly possible. The efficiency will
likely be limited by the number or type of joints in the assembly including

Just for fun once, I decided to make the smallest possible antenna and
see if I could make any contacts. I wound about 30 week of #12 solid
insulated wire around a 3/4" PVC pipe. Parallel to it and electrically
in series, I created a tunable tubular capacitor using copper pipe and a
threaded br
There is a Yahoo group called CW-CODE-WARRIORS that has a ton of data
on building Mag Loops, as well as numerous builders that have had
great success with the antenna from all over the world. Check it out
if you are interested.

And I'd like to emphasise that this thread is about physically small
"magnetic loops", not fullsize quad or delta type loops which are
efficient radiators with relatively high radiation resistance
Anyone using the K3 and the ICOM SM-20 mic? What desk mic is good to use
with the K3? Anyone try different combinations and reach any conclusions?

I could not agree more. We used mine at the WS4Y FD for the CW station and
it was roundly praised by some very accomplished CW contesters. So far FD
has been my only chance to try it in contest conditions but I'm thinking
about a serious effort in the 160 CW contests this winter.

IMO you cannot beat the Heil Pro 781 with the K3.
Sounds amazing with the internal TX EQ adjusted correctly.
Can be configured via a boom or desk stand.
I believe it costs less than the pricey SM-20 though the boom or desk
stand will be extra.

I use an SM-8 which is similar. I get wonderful audio reports and I'm
very pleased with its operation. I'm sure the SM-20 will work well.

Hi Gary,
Seems to me that you are right on with all but the very last part... and that
may need some investigation, with relation to the DDRR antenna.. that is a
loop, and horizontal, over a very good ground. Just a thought

That's not really true. The DDRR is NOT a loop antenna. The DDRR is a very
short vertical with top loading contributed by a shorted transmission line
(formed by the horizontal loop and the ground plane). Check the field

Yep, I agree. And you get good button/switches, too.
