I am wondering the same information, I would like to buy an extension
cable and then , how long can the cale be? I plan on mounting the FC-
40 on my 60 foot tower and running a sloper wire.

Dar friends,
I am using the FC40 with my 857 and 897 under several

circumstances.

In mobile I tested the FC 40 with 1 3m whip against the ATAS 120.

my

opinion is: Atas on 20-10m better, FC40 /whip combo on 40-80 better.

6m no chance of dx for a test.

my question: does anybody know a source for an additional extender
cable for the remote control line? I do not want to cut the

original

cable.

Good morning,

I am going off to visit my parents in Alberta next month and
thinking of bringing my FT-857 and FC-40 with me. I am planning on
using one of the electric fences as an antenna. (The fence is not
energized, since no cattle are using this field) The fence is
approximately 300 m (1000 ft+) approximately 60 cm (2 ft) off the
ground and terminated to the ground at the far end. My question is if
this would be a viable antenna system? Is there anything I should look
out for?

Chuck,
With a 102" whip, you get 6 meters through 40 meters.

You really want the wire from the tuner to the mount as short as possible, although it will work with just about any lenght. Just remember that the "antenna" starts at that connector on the tuner.

I have my FC-40 mounted in my aluminum toolbox. I have very little problems with tuning the 102" whip. It usually loads in about 3 to 5 seconds.

Hope this helps.

Thanks,

Mike, KB5OZE

I am thinking of buying a FC-40 for my pickup truck installation and
had a few questions.
1.Will the tuner with a 102" whip tune 10 to 80 meters?

2. How long a wire can be used to connect the tuner to the antenna mount?

I was thinking of mounting the tuner on the side of the tool box. It
would be about a foot from the tuner to the mount

Greg:

Don't use coax to connect your tuner to the antenna - the grounded
shield acts like a capacitor to ground and your tuner won't 'tuner'.

You need to make the wire from the lug to the whip as short as
possible - have you considered mounting the FC-40 outside the
vehicle?

You can use an 4:1 unun or an autotransformer in reverse- check out
K0BG's site at . I have used an
autotransformer on an powdered iron toroid core on my FC-40 to get
my 102" whip down to 60 meters, although I lost some S units on
recieve on higher bands.

Hey all,

I sold my truck with the 102 inch whip....I had the fc-40 about 3
inchis away from the inside lug of the ball mount so it was

perfect

for 10 gauge wire from the fc-40 lugs to the ant.

Now I cannot drill into my (new) Olds Bravada, so I need to figure
another way.

Can I cut off the end of a 15ft coax, wire it to the tuner and
connect the other end to a pl259 mount for the whip, off the

bumper

sor something?

Didn't think I could use a coax.

Also, what if I used a 4:1 balun in reverse to accept the wires

from

the tuner and adapt them to the coax to make the run over to the
whip?

Can a balun be used in reverse? Could use it in my shack to

attach

attick mounted slinky to the tuner.

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.

I have used the LDG tuner before and it has a much larger span of
tuning. You can "make" the LDG tune a non resonant antenna easier
than with the Yaesu. The LDG Tuner is capable of a Antenna
impedance: 6 to 800 Ohms (Approximately up to 10:1 SWR)



where as the FC-30 can tune 17 to 150 Ohms (25 to 100 Ohms on 50 MHz)
The info was taken from the Yaesu 897D brochure

Thank you for being the first post and welcome all to the new

It makes 60 meter in the USA a WALK IN THE PARK to use. I made

I am using the tuner with My 897D on field day and will be

Hi,

Looking for some opinions on operating a FT-857 with the FC-40 dockside portable. After reading the June issue of QST and reading 'A Portable Inverted V Antenna' article, I am thinking of modifying it. My plans are to change the antenna from the inverted V to a loop and then use the water for the ground. My other choice may be to use the triadic on the sailboat, but since I plan to operate on the dock, I am worried about the stress which would be placed on the patch cables to the rig. Also by using the loop it would also allow for more portable operations in the future. Any help would be appreciated.

Well, right now I am using a standard 102" whip. I am still in a testing phase. I have had some problems using a coupler in the Dakota. With the current setup though, the FC-40/FT-857 was receiving almost as good as my FT-847 on a 60' long wire with a SGC-230. I have a Houston trip (driving) coming up and hopefully will have more information during and after that. I am thinking of replacing the 102" whip with something a little longer, maybe in the 12' range. I will definitely update everyone on how it goes.

Thanks,

Mike
