Are you planning on using it as a loop? I made a loop for field day
back in June with the FC-40 and it was 540 foot long. I had a blast
with it, I "snuck" off the band I was working, 160 meter, and
listened and tuned several bands and had a blast. I attached ladder
line from the tuner to the wire for the loop also,,,,LET US KNOW HOW
IT WORKS!!!

Okay, I have followed the postings so far and have the radio and
antenna and tuner installed in the TJ.
I have grounded the exhaust system as advised. I placed two large
ferrites on the fuel pump line. I put ferrites on the brake light
power lines.
Noise is still at S-7 to S-9. Pretty disgusting.

My next direction is the injectors, I suppose.

Any other ideas out there?

I tried the link, but failed to see where it answered my questions...
maybe I missed something.
Basically I want to know if the CT-62 cable and the cable to the FC-40
can work at the same time (as they go to the same jack, I believe).
Thanks, Chris, VA3ECO

Jeff:

My setup won't tune below 5 MHz, even with a stepdown toroidal
transformer with the 102" whip. Not surprising as the FC-40 is only
advertised to go down to 40M with a 102" whip.

If I want to use 80M I'd have to use a Hamstick, a longer whip
(while stationary) or a loading coil. I'm still playing with all
three to see what works best.

6 meters tunes up no problem, I can hear local beacons but seems
like there is not much 6M activity around my new QTH.

10 through 20 meters work great and I love being frequency agile and
having a rugged setup for off-road.

Jay,

Out of curiosity - have you had any success with the Wrangler

setup on 6M?

Greeting FC-40 users!

I have uploaded some pictures of the setup in my XYL's Jeep

Wrangler

TJ in the folder "W6SH Jeep Wrangler TJ - FT-857D & FC-40".
Although my XYL would probably tolerate me putting the big ol'

ball

mount over the rear fender for the whip - in the interests of
matrimonial harmony I decided to try for as much of a "bolt on"
installation for a FT-857D / FC-40 / 102" inch whip combo as I

could

manage. It is a low-profile look and happily so far my XYL

approves.

This setup is just what I ended up with and is probably not

optimal -

but maybe someone will get some ideas for taking their own FC-40
mobile. Going HF mobile means making compromises - but I have

been

pleased with the FC-40 since I got it last Christmas.

Some mobileer purists would argue for bugcatchers or

screwdrivers,

but the whip has the advantage for a Jeep of being somewhat more
rugged when going off-road. I work downtown and the whip also

is

easy to pull down to a tie down mounted over the driver's side

of

the windshield when entering parking garages.

I have been pleased with the performance on 20 meters and higher
freqs. Tuning on 40 is sometimes hit or miss - the TJ doesn't

have a

lot of sheet metal for a ground plane. Interestingly, 40 tunes

up

better when the whip is pulled down. I am experimenting with an

1:4

toroid autotransformer and more grounding braids to see if 40

will

tune up better.

One issue I haven't had too much trouble with is RFI. TJs are
notorious for fuel pump noise, but I quieted mine down by

placing

several clamp on ferrite beads on the fuel pump power lead as it
heads into the gas tank (this is a tight place to get into,
however). I also put ferrite beads on the taillight wires to

keep

down fuel pump RFI - that seemed to help too. Be sure to ground

the

tailpipe as it can radiate ignition noise too.

I still get some ignition noise at times despite having several
beads on the ignition wires, I have got some copper conductive
adhesive tape however and I will cover and ground those ignition
wires as suggested by K0BG (I highly recommend his site for
mobileers at www.k0bg.com).

The radio is mounted in the aftermarket metal "Insta-trunk"

which

provides some theft protection. The FC-40, and whip are mounted

on

a "Arizona Rocky Round" Jeep rear double antenna mount which is

made

by Rick at arizonarockyroad.com . This mount uses the existing

bolt

holes for the rear tire mount. The whip is a RadioShack 102" CB
whip. The whip insulator is Delrin and available at

geotool.com .

Voltages at the tuner output can be very high so a good

insulator is

required here.

The VHF antenna is a Comet SBB-7 foldover.

I used #10 dual wire from the battery posts - this is hidden

along

the passenger side floor - both leads are fused. I had to

replace

the 7 year old battery as it was weak and used a Optima yellow

top

deep-cycle gel battery. I found a cheap 1 Farad car stereo

capacitor

at a flea market and put in the trunk to on the power lead to

ensure

there would be no voltage dips while transmitting - although

this is

probably unnecessary, it looks good!

I used the existing brake light grommet in the tailgate to bring

out

the HF coax lead, I did have to drill another 1/2" hole in the
tailgate to bring out the VHF coax and control lead.

I coiled the HF coax into several 6" turns before it entered the
tuner to reduce any coax radiation. The mounting plates that

come

attached to the FC-40 were removed. The tuner is mounted to the

back

of the Arizona Rockyroad mount using plumbers straps and

stainless

self-tapping screws and grounded to the mount and tailgate with

1/2"

braid. The tailgate is also grounded to the body with 1/2"

braid.

Conductive grease was used at all ground points.

So far I have been impressed with the FC-40, it performs as
advertised and seems pretty stable on the road. So far I have
worked North America and Europe, I have had S9 reports from W2

and

VE7 almost had a VK-land contact during a late band opening on

20m a

few nights ago, except he went QRT too soon.

I continue to try to improve the setup and I will add new

pictures

if I think I have made any leaps forward.

That's really interesting. I'm running a 102" stainless whip and haven't had much luck on 20 and 40. 20 tunes up great, but 40 tends to spike high when I'm transmitting.

I've only been playing with this rig for a few days. I'm sure I haven't gotten rid of all the 'operator limitations.

Glad to hear that this rig can work so well. I know that thus far, I've been very impressed.

I just came back from a round trip from Florida to Wisconesin. On the way up I was ab
le to get into nets on 75, 40, 20 meters. On the way back I had a QSO with a ham in Boston and at the same time was able to chat with his brother in Texas. This was done on 20 meters in the morning. We had such good results that we tried the same on 15 and 17 meters. This time I only could QSO with the ham in Boston. This QSO lasted close to two hours. Note the "K" factor was 1 or less that day for some odd reason.

I use a fiberglass 102 inch whip off the back of the vehicle and only running 100 watts from the FT-857D.

As for the 75 and 40 meter contacts, they were fine with reports of 5/6 to 5/8.

I use a 102 inch whip and the FC-40 on a Jeep
Wrangler. I get good reports down to the three top
channels of 60 meters. 40M is okay as well.

80M is out of the question with the 102 inch whip.
I have an 80M hamstick, but have not really tried as
yet to get it to tune there and above.

I have a 6 foot wood fence that protects my back yard. It must be
around + /- 200 feet in roughly a square configuration. I used 4 foot
fiberglass fence sticks and nailed them to the posts around the yard
above the wood fence. The wire is attached above to those sticks
which gives a total height of about 10 feet for the antenna. The
tuner is outside the shack and grounded right there. The antenna
tunes ALL bands 160 through 6 meters with no problems. I get great
reports too. If interested I'll send a picture. It does not look
like an antenna!

I got from a local fishing tackle manufacturer (Brisbane, Qld,
Australia) who in the past also made quite a few tapped whips for
RFDS applications. They are not doing the work any more now that
auto-tune screwdriver antennas have generally taken over for
Australian HF land mobile services. They told me I was the last
customer as I took their last blank.

So I guess the answer is no, not available any more.

HI !

Wire length should be something else than half wave to
avoid high voltage feed point and arcing inside the
tuner. Sometimes I had very nice blue shining light
inside my old manual tuner when running higher bands.
(That time I used 600W output and antenna was G5RV)

I made that excel file to see same time all bands
compared to half wave length and wire length.When the
wave length divided by wire length gives something
like 1,15 (2,15 , 0,85 etc.)it is enough far away from
high voltage feed point.

My wire length is 51 m, 10m up and 41m horisontal.
(51m = 167 feet) 41m horisontal is because if changing
later to dipole, it is already right length.
10 meter comes from distance betveen balcony and
horisontal wire. First the vertical length was
something else ( I dont remember anymore) and some
bands where difficult to reach good SWR (less than 2
).
I shortened vertical wire a bit and after that it was
better.After making better ground everything was ok.
My tuner is AH-3, AH-4 is quite similar with longer
wires ( 51m it is not yet real long wire..) .
