:    Untill somebody else will do a side-by-side comparison,

I have done just that.  My test was similar to yours as I compared the
Isoloop to an 80 meter dipole tuned with a Johnson Matchbox to the
20 and 15 meter bands.  (The dipole was mounted inverted vee fashion
with the apex about 5 feet below the Isoloop, which was on a mast about
50 feet above ground.)

One difference between my test setup and yours is that I used a coax
switch so I could do instantaneous comparisons of signals between the
two antennas.  In several days of testing, I was never able to see a
significant difference between them.  (Actually, there was one exception
to that statement:  A station in Calistoga, about 10 miles away, was
about an S-unit stronger on the dipole, but I don't consider that
a valid test on the 20 meter band.)

: I will

: mean worse performance,    ...

The laws of physics show no such thing.  It is theoretically possible
for a small loop to be 100% efficient.  It's true that it's hard to
approach that ideal in practice, but the Isoloop comes impressively
close.

As I said before, however, I am not a big Isoloop fan.  I still think
$300 is a lot to pay for an antenna that performs almost as well as a
dipole.  But for some situations, it might make sense.

: In short, if an antenna sounds too good to be
: true, it isn't true.  There is no snake-oil cure for size.

That criticism might be valid for some antennas on the market (the
similarly-named "Isotron" is one that comes to mind), but the Isoloop
works as claimed and is a perfectly reasonable antenna to use.

John, since you seem to have this amazing ability to locate people
throwing away their Isoloops, would you let me know next time
it happens?  I'd be glad to pay shipping to get a free one.

Robert: I have an HW-16 (I don't have the vfo!).  Heath can still supply
manuals.  The HW-16 has a built in vfo for rcv only.  The external
vfo is only used in transmit.  You must be sure that you are transmitting
and receiving on the same frequency!  The back of the HW-16 has an RCA
phono jack for the signal from the vfo.  It also has an octal socket
(like a tube socket) for supplying power to the external vfo.
If you need more help, send me your e-mail address.

I read another post that said it is common in other parts of the
U.S.  I guess we just don't do it in Colorado.  I think it would
be better, however, to say CQ instead of "blah blah blah monitoring."
It just seems more to the point.  Don't ya think?

Art...we have been living with this for more than a decade here in
Canada...a VERY rough quick conversion is double the C and add it to 32 F.

Example: 10 degrees C x 2 = 20 + 32 =~ 52 degrees F.
10 degrees C is actually 50 degrees F but you can see how close it is.

Hope this helps....Rob

Heh, heh, an even easier way to solve the whole problem would be for
us Americans to just drop F, then there would be no need for conversions.
(Easy for me to say--I was trained as a chemist.  What the heck is
degrees F??  ;-)  Does anyone in the world besides us use F??

Why don't you?  The poster also said:

"In other words, you may continue to operate until you eventually receive
your renewed license =OR= until you are notified by the FCC that it was
not renewed."

See the "=OR="??  That implies if you don't renew and don't tell the FCC
you can operate forever!

(Not what he meant, but he did say it...)

Not if you don't have it to begin with, it isn't.  (And, you don't know

I have just been notified that I was asleep at the wheel.  The

when it goes to 10.0V, not 12.0V.  Whoops!

Same problem.  Substitute 10.0V for 12.0V.
Gotta get a new CPU for the space above the shoulders.


                        -Ken

p.s.  for you electrochemically inclined, the reason you need to charge
to such a high terminal voltage and evolve oxygen at the positive electrode
to achieve full charge is that the equilibrium potential for the
Ni(3+)/Ni(2+) combination is 1.33V ref. hydrogen electrode in KOH, while
it only takes 1.23V to split water.  So, in order to run at equilibrium,
you are already getting oxygen evolution.  You need an overvoltage to
overcome polarization and kinetic effects.
