I've been holding back the results for fear that some upstart company

If you're in line of site of and in the path (direct or 'knife edge
refraction from a mountain as was in Leukemia Valley in Northern NJ)
then you can be in serious trouble. Generally the beam width is small and
as long as the antenna is high enough over head it probably isn't saturating
anything below.

Doesn't anyone read the Regs anymore?

97.19(c) When the licensee has submitted a timely application for renewal
of an unexpired license (between 60 and 90 days prior to the end of the
license term is recommended), the licensee may continue to operate until
the disposition of the application has been determined.
---

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.

So, if you never renew and you never *tell* the FCC you didn't renew,
you can operate forever?  (Yeah, right!)

Subject: Mobile HF Noise Problem
To: [e-mail]

So, HF mobile elmers, what should I do to reduce this noise?  I'm sure
there are tons more stations to hear and work....


Had a similar problem on a Pontiac. Wound up buying a shield kit for the
ignition wires at PEP Boys. This puts braid-shielded wires in and a metal
distributor cover. Made a +20db to s7 improvement, which the FT-757 blanker
could handle.

I have a TS-50 with hamsticks, and in my opinion the only weak point in the
ts-50 is the noise blanker, they need ft-757 lessons at kenwood. My present car
is very clean noise-wise, but the '50's blanker does NOTHING about power line
noise.

Good luck!

Subject: Mobile HF Noise Problem
To: [e-mail]

   There is a big, classical design error.

   Just why do certain radio manufacturers provide + and - leads both
fused and tell people to wire both back to the battery ?  Beats me!
With the ground of your antenna you create a wonderful, classical
ground-loop involving the battery and the engine compartment. Using a
direct radio-body ground doesn't remove the loop but it does reduce it
and keep it out of the noisiest areas.

   Make sure that the battery to body connection is huge, clean, short
and secure and you have no need of that - lead.

   You need a good short wide, low inductance strap from the radio's
chassis to the car body. Take the + lead into the engine compartment,
keep it as clear as reasonably possible of other cables to the battery +
you may want to put a few turns of the +lead (only) round a ferrite
toroid (Fair-rite #43) close to the radio.

   The theory that someone used was that the separate ground lead would
remove any noise voltages dropped across the battery ground lead, and
assumed that the battery looks like a monster, perfect capacitor. They
neglected the existance of other grounds.  Sure, local grounding is
also theoretically imperfect, but usually turns out to be a lot quieter.

  The fuse in the - lead,  I thought you'd never ask !  if you wire the
radio - direct to the battery, and the main battery - lead fails, the
starting current could try to pass from the car structure, via the
antenna cable, radio and radio - cable to the  battery.  The fuse is to
prevent fire.   I've seen a throttle cable burst into flame on a car
where a mechanic had forgotten to reattach the engine ground strap.


  Hope this helps a bit,
                            David  GM4ZNX

One FTP site is:

I've used the program and it is a great tutorial, although I have not

Making your own is probably the easiest way.  The formula is:

C = (5 / 9)*(F - 32)

    or...

(C - 40) = (5 / 9)*(F - 40)

Both work--it just depends on which is easier to remember...

First, you said you had TVI, one indicator that something was wrong,
possible antenna defect, maybe.

Second, lowest SWR of 2:1 on some bands? It really sounds like there
may have been some problems w/the antenna, feed or both. Also, there
is an adjustment on the small loop inside the dumbell housing. The
proximity of the small loop to the bigger loop (yes, there is an
andjustment for that) is set at the factory but in some installations
it may be necessary to move the feed loop closer/farther from the outer
loop. Did you do this? This always corrects the SWR problem. I suspect
that you never had the antenna to true resonance. A local ham here in
Maryland adjusted his antenna thusly and commented on the improvement
that made. I had no such problem w/my attic installation.

Regarding the tuner that AEA sells for the antenna; It's an automatic
microprocessor controlled unit intended to make moving up and down
the band very quick, w/memories and all. It has NO TUNING
CAPACITORS. As the manual states an antenna tuner will not tune the
loop to resonance. Again, the point is the antenna must be resonant. That's
the virtue of the design...

If you're trying to compare the performance to a tribander or full size
dipole in 'free space', you've missed the point. Another ham here in
Maryland sold his Isoloop in disgust after he mounted it on top of
his tribander on a 40 ft tower. Why waste money/time if you have other
alternatives. You get this antenna when you have restrictions and no
other alternative.

FYI, read the May 1994 issue of QST for an ARRL review of a homemade loop.
They got the same results I did running QRP (5 watts) on 30 Meters...

CALLSIGN.CS.BUFFALO.EDU states in the info file that it is current as of
January 1994.  The FCC only puts out a full new list once a year and they
always update when the new list comes out.
