I stand by my statement.
A statement by one who has never owned a Kiwa MW Loop and who from his
postings had only a short and cursory use of one.

If you have decent filters in your radio, you
don't need the regenerative controls of the Kiwa.
That's nonsense and shows your lack of experience with the Kiwa Loop. I ran
it for years with my previous Drake R8B and for the last eighteen months
with the Icom. The Icom has superb filters yet the regenerative feature of
the Kiwa improves substantially on the Icom's filters.

If you want to brag about long distance low power transmitter DX, then the
following is just a sample of the many exotic stations I receive on my Kiwa
loop:
KVNS Brownsville TX
KCNZ Cedar Falls IA
both 1000 watts or less and well over 8,000 miles from my QTH.

In fact, I challenge you to find anywhere on international forums any
results that come anywhere near my published results using the Kiwa MW Loop.
I've never seen any Quantum or Wellbrook results that come anywhere near
matching the results I get from my Kiwa Loop.

doesn't change my opinion, nor did I find the regen useful when I
tested the Kiwa with a R8B.

When the Kiwa was $250 at the flea market, yeah, whatever, buy one if
you like it. At the obscene prices people pay on ebay, you are better
off investing that money in a better radio.

Regarding DXing with a loop, here is the LAX TIS I recorded from
central Nevada

About 250 miles. As you know, TIS is flea power.

I can't agree with this statement at all. If you know how to use the
regeneration circuits properly then you will get superb results from the
Kiwa MW Loop.

I have owned the Kiwa for many years and taken it on countless
DXpeditions
and it's performance is awesome, rivalling and often beating a well laid
out
1000 foot beverage antenna.

At the following link you can read exactly how the regeneration feature
operates and gives such excellent results

They commonly sold used at the flea market for $250 to $300. I believe
$400 was the new price.

I've had the opportunity to try out the Quantum, Kiwa, and Wellbrook at
the same time. If space is an issue, get the Quantum. If you have a bit
of room, get the Wellbrook. You need a version with a 3ft (meter) loop
to get decent AM BCB. The kiwa is OK, but not as good as the Quantum in
my listening session. Both the Kiwa and the Quantum can be tilted as
well as rotated. I didn't find that useful, but maybe there are time
when that would come in handy. A wellbrook isn't easy to tilt.

The Wellbrook ALA-100 really works well if you set up a large loop. I'm
using 4 turns about 6ft on the side, which really eats up a corner of a
room. [It's an experimental antenna of sorts, and I'll probably settle
for a double loop for indoor use, and use the larger loop when
camping.] Some of the local AM BCB stations are so strong that my 7030
has to cut in the attenuator. Many are so strong that the preamp
doesn't turn on. Note that you need some spacing between the loops to
get any decent HF performance. About 8 inches does the job.

The regenerative controls on the Kiwa are quite useless if you have
decent filters in your radio. Given the limited bandwidth of the Kiwa,
I can't see why you wouldn't choose the Quantum instead. The Wellbrook,
not using a core but rather depending on aperture, works well above HF,
certainly up to 50Mhz. I've used it as low as 24Khz, which has a Navy
FSK signal.

Lastly, the Wellbrook doesn't need to be tuned.


I can borrow the Kiwa again, but I really rather not waste my time
screwing with it. It was overpriced at $400 new, now the ebay prices
are just plain silly.

As I have played with all three (Kiwa, the older Quantum, and my
tweaked ALA 100 multiturn loop), I feel quite confident in my
assessment. The Kiwa simply lacks the aperture of a stock Wellbrook,
let alone a multiturn Wellbrook.
