Well, I'm not an Isoloop advocate, but it definitely sounds like there
is something wrong with your unit. It should be within a dB or two
of a dipole at the same height on all bands.
(Now, whether it's worth the money or not is another question...)

I wonder if your Isoloop might have had a problem. The computer RFI
could be a clue: I would expect the Isoloop to have less RFI than the
3.5 MHz dipole since the dipole is probably closer to house wiring etc.
I recently bought a used original Isoloop (14-30 MHz) that I was going
to use on Field Day. My plan was to put it up on a 50 foot mast, with
two of the mast guy wires acting as an 80 meter inverted vee fed on both
80 and 40 meters with 75-ohm twinlead into a Johnson Matchbox tuner.
However, I found that even on 20 meters, the 80 meter inverted vee
performed the same as the Isoloop. I did an A/B comparison using a
coax switch so I could instantaneously compare the two antennas using
off-the-air signals -- I could see no significant difference. Of course,
neither antenna did nearly as well as my TH7 tribander at 55 feet!
So I didn't take the Isoloop along on Field Day. Since the 80 meter
dipole performed just as well, even on the higher bands, and since
the dipole + matchbox had greater bandwidth than the Isoloop (less
retuning), I just used the dipole on all bands.
: Even with the slower stepping, tuning was a real pain in the bum. ...
I found that using an MFJ SWR analyzer with the Isoloop works great.
Use an antenna switch so you can easily connect the analyzer to the
antenna, tune the analyzer until you hear the whistle in the receiver,
and tune the antenna for a dip.
Bottom line: The Isoloop would be a good solution for some situations
such as operating from an RV in a campground or from an apartment
situated such that you could put up an Isoloop but not a dipole.
But I agree that for most people, $300 is a lot of money to spend for
an antenna that is almost as good as a dipole.

I got a list of the local police and shariffs departments from serveral
of you but now I want even more!!! is there any that list the ones they
refer to when they say go to channel 9 or goto cannel 3. This happens
all the time with the san jose pd. They go there when they want to have
a little more privacy or soemthing...
Also I am still looking for the meaning of all the numeric codes they use
e.g. 415 is a disturbance or fight I think, 10-51 is under the influence
or crazy or somehting like that any list of the meaning s of therse would
be greatly appreciated.

Ham Radio Operator Assists in Catching Car Thieves
Cathy Dicker
Chris Dicker
Scott Diamond (KB7ZHB)
On Sunday night at 11:30 p.m. on June 12, 1994 I was almost asleep when our
teenage son, Chris, came bursting through our bedroom door exclaiming that
someone across the street was trying to break into a car. With two teenage
sons and an eleven year old son in our house, it seems like the kids are
always hearing strange noises. My first reaction to this news was to cover
my head with a pillow and try and get back to sleep. Fortunately, my
girlfriend Cathy decided to see what was going on.
While half asleep I overheard her and Chris discussing what they had seen.
Apparently a man and woman had driven up and down the block on a motorcycle
and when they approached the vehicle across from our house, the woman on
the motorcycle had said, "this ones open". She then got off the motorcycle
and the motorcycle drove away. She entered the vehicle on the passenger
side, moved over to the driver side and was adjusting the seat, steering
wheel and grabbing at the dash. At this point, my girlfriend Cathy yelled
back to me that I really should get out of bed and look at what was going
on.
As I walked to the window to watch, Cathy yelled down to the woman, asking
her if that was her car and what she was doing. She was out of the car at
this point and yelled back that the car was her friends and that her
boyfriend was going back to get the key. Cathy yelled back "Well then you
won't mind if we call the police". At this, the woman shrugged, reentered
the car and continued moving the seat and messing with the dash. We were
starting to get pretty suspicious so we went ahead and called 911.
After a couple of minutes her boyfriend came back on the motorcycle and
Chris overheard her telling her boyfriend that we said we were calling the
police. The boyfriend said that he would meet her at home and then drove
off. She stayed in the vehicle for a couple more minutes continuing to mess
with the dash and then she got out and started walking down the street.
When she started walking down the street we got really suspicious. Maybe it
was her friend's car but why wouldn't she wait by the car? Why would she
walk away? Chris decided he would follow her and see where she was going
and in addition he brought along a pencil and sheet of paper. If the
motorcycle came back again he wanted to write down the license plate
number. I thought about what was happening and decided that this was just
too odd. I try not to invade in my neighbors private affairs but I wanted
to see where she was going. Dressed only in my bathrobe, I got my car keys,
wallet, handheld ham radio and went out to the car to follow her.
It was overcast and rainy and by the time I got out onto the street I
couldn't see where she had gone. I drove down the street and saw Chris on
the corner. He pointed down the street where she was and got in the car.
I had my ham radio with me. For those of you not familiar with ham radio,
there are local repeater stations which receive your incoming signal,
amplify it and rebroadcast the signal, thus allowing local ham operators to
cover a large area with their signal. In addition some of these repeaters
are connected to phone lines and if you are a member of a ham radio club
you can use these repeaters to make local phone calls. I was a member of
the local K7WWR repeater and I had used this repeater many times over the
winter on cross country ski trips when we wanted to check to see how the
kids were doing at home.
I'd programed my handheld ham radio with the tone sequence for home so I
called home to see if the police had stopped by (at this point we were only
two blocks away from home). There was no answer on the phone at home and I
figured she was talking to the police. We still slowly followed the
woman.
During the whole time we were following her we stayed back about one
hundred yards. I didn't stay back to hide, a car with it lights on crawling
along at walking speed 100 yards behind you is pretty noticable, but
instead I stayed back because at this point I wasn't all that certain that
she was guilty and I didn't want to scare her. I kept at a nonthreatening
distance so she wouldn't be scared and besides if she really was dangerous
and had a gun I didn't want to be too close anyway. I'm sure she saw us
behind her, but she probably didn't realize that while following her I was
using my ham radio to try and call home and that I could use it to contact
the police if necessary.
After a couple of minutes I called home again. Cathy answered this time
and said the police had stopped by and they said the car had been punched.
Meaning that someone had tried to rip out the ignition. It was sure looking
like the person we were following had tried to steal a car. Cathy had told
the officer in the car that we were out following the woman. Cathy told
the police to look for our car and that I had a ham radio and would
probably be trying to contact them. The policeman didn't really understand
this. After all how could I contact the police with a ham radio? He asked
Cathy if she was in constant radio contact with me. Cathy explained to the
policeman how I could make a phone call and the policeman then drove off to
see if he could spot my car. At this point we were about five blocks away
from our house.
After Cathy told me about the car being punched, I decided I should call
911 directly. My handheld ham radio can store up to four phone numbers in
it's memory. Fortunately, just two weeks before I'd thought, if I'm ever in
an emergency I'm going to be too nervous to enter the correct tone
sequences. At that time I'd gone ahead and assigned one of my autodial
sequences to 911. I signaled the repeater up and made the connection to
911. At first there was some confusion because the repeater is located in
Portland and when I described our location they weren't sure where we were
in Portland or Vancouver. Once they realized I was in Beaverton they
transferred the call to the Washington County 911. I repeated my story with
the Washington county 911, they said I should contact the Beaverton police
dispatch directly and gave me a number. I explained that I was using my
ham and that it was difficult to redial and asked if they couldn't
transfer. The operator said she was transferring me but that if I got
disconnected I should dial directly.
We were now about eight blocks away from home and were finally connected to
the right dispatch. At first the Beaverton dispatch wasn't sure what we
were calling about but she soon connected our call with the search the
police were doing in our area and asked for our location. At this point it
was really exciting for us in the car. The woman who broke into the car
was walking down a number of small streets and throughout our conversation
with the Beaverton dispatcher we were relaying our position as we turned
onto each street. In our minds we imagined her relaying our coordinates
over the police radio to the local patrol cars and the patrol cars zeroing
in on our position.
Up ahead of us we saw two cars that had turned down the road we were on. It
was too dark to see the cars but we thought they might be police. As they
got closer I saw that they were police cars and I flashed my bright lights
as they went past. Quickly, I told the dispatch that the cars had just
passed me and that they needed to turn around. The police went one more
block then turned around and headed back our way. I leaned out my window as
they came up from behind. The lead police car pulled alongside of our car
and I pointed out the woman we had been tracking.
Both police cars went ahead and pulled up alongside of her, and at that
point a third police car showed up. As the police cars pulled up, it looked
to us like she was trying to cut through the nearby houses to avoid them.
Fortunately the police were too close and jumped out of the car to question
her before she could go anywhere. At that point we headed home, elated that
we'd been able to direct the police to her after tracking her for ten
blocks.
Later that night the police came to tow away the car across the street from
our house. It turns out that the car was stolen. I don't know why they
broke into a stolen car. This is just a guess but perhaps it had been
stolen earlier in the day and left in a 'safe' place before taking it to a
shop to be taken apart at night. The police called back later that night at
1:30 a.m. and then at 2:30 a.m. (I was too excited to sleep much anyway) to
ask us for the details of what we had heard and seen. The officer we spoke
with said that several arrests were occurring as a result of catching this
person.

Rob, I ran into the same problem when I started doing the local ARES
newsletter. There is no source that I could find. One of the gentlemen in my
HAM class is a commercial artist and we are working on a set of amateur radio
clip art to be distributed via shareware. It should be ready by the end of the
year.

FIELD DAY 1994
CALL : WA3NNA
ENTRY CLASS : 1B - battery - 1 operator
SECTION / LOCATION : SNJ
Between 21st and 22nd Street; Ocean City NJ.
On the beach; About 50 yards from the ocean.
RIG : OHR Classic (5 watts CW - 20 & 40 meters)
ANTENNA : half-wave vertical wire - supported by a kite.
POWER SOURCE : 12V Ni-Cad battery pack
TOTAL ON-AIR OPERATION TIME : Less than 8 hours
FINAL SCORE:
73 QSOs on 40
35 QSOs on 20
-----
108 TOTAL QSOs (x2) CW (x5) 5 watts = 1080 points
100% emergency power = 100 points
Operation from a public place = 100 points
TOTAL SCORE = 1280 points
COMMENTS :
The thunderstorms never materialized but the winds more than made up for
it. High un-cooperating winds kept the kite antenna from flying early
Saturday afternoon. Finally (with a longer tail on the kite) I was on the
air shortly after 2100z. Operated from the beach from about 5 PM Saturday
until dark and then returned 9 AM Sunday. 40 meters was much better than
expected. 20 seemed much worse than last year. Tried a couple CQs and
worked 3 stations but the rest were all from just tuning and calling. In
general, was able to work about 80% of what I called.
LESSONS LEARNED: ;-)
Delta kites do not like high winds unless they have a *very* long tail.
A half-wave vertical on 20 works better than a full-wave vertical.
Use a dupe sheet next year. Memory starts to fail after about 50 QSOs.
You can still get a nasty sunburn even under a beach umbrella >ouch!<
FD is too short. All of this preparation for only a few hours on the air.

Greetings, all.
As I have not achieved critical mass in the number of orders for the
Motorola GPS engines, I am shutting down the group purchase.
I am on vacation for the next two weeks. If, upon returning, there has
not been enough orders received to reach the magic 100 mark, I will be
returning the checks to those who have sent them to me, and
discontinuing any efforts in this area. As of now, I have orders for
about 35 units. For those of you interested, that's about $13,000
sitting on my desk.
Thanks for your time, efforts and wonderful interest in this matter.

I have purchased a Heathkit model HW-16 and it's companion VFO (HG13).
Being new to Ham radio, I am confused as to how to interconnect these two
units. I received a partial manual, but it does not have any
illustrations on how to put these two units together. I know that the
manuals are not complete as they are photo-copies of the original and
there is not enough information for me to get things up and running. Does
anyone out there know of a source for complete manuals or perhaps that
might be familiar with these units. I believe that Heathkit is out of
business. I can receive signals, but can't seem to get this thing
together for transmitting. Thanks in advance for any help. KE6FDU (new

Well, Scott, about 70 or so miles to the west in Leesburg, VA, where we
had a super nice Field Day site set up at Ida Lee Park, the winds were
so strong on Sunday that your vertical would have been a sloper or
maybe even a horizontal!! :-)

This actually happened. I was giving a commercial license exam, and
this ham came in to take his GMDSS Repair license exam (element 9,
for you who know the commercial regs) to go along with his General
Radiotelephone Operator's License (GROL).
Anyway, we need two forms of picture ID, so he starts flipping through
his wallet, and I see what looks like a pictures of equipment. I ask,
and he shows me a beautiful picture of his mint condition Collins
KWM-2 station.
He has no pictures of his family (wife OR kids), but he does have a
picture of his HF station...

The problem is the cheap radio. No doubt it tunes in 1 kHz steps. To
reproduce voice accurately, you have to re-insert the carrier accurately.
A radio with 100 Hz steps may not be acceptable to finicky listeners.
