Hi, the rusty connector diagnosis makes sense; I had a similar problem avec water in the control cable connector. I dried it out and then sealed the area with putty and then wrapped it with vulcanizing tape. No problems during a long wet, salty winter.

I would however recommend against WD-40 on the connector.

WD-40 has silicone in it that can interfere with conductivity, and it will trap dirt. Although I might get flamed, I always liked freon-12; it was cheap, it would clean almost anything and it was so volatile that if water was present, it would aggressively dry the area with no residue.
Check your local electronic store to see what they have. You might find a spray can of something that you can use.

I had almost similar HVSWR and thought it was the rig.? Then I checked the tuner and later noticed that the control cable looked rusty.? I reinserted the cable and also reset the tuner.? All's well now.

hi Dave, i've been using fc-40 over a year. no probs.

I'm assuming you've checked ground and the coax hasn't gone o/cct....to the tuner I mean, cos y'd have poor rx, and HSWR indications... so it could be a faulty control cable to the fc-40 (cn borrow one from a dealer to check?)

or try resetting both the 857D and the FC-40.. remember to set the CAT/LIN/TUNER back to "TUNER" after resets.

alternatively., does it run "off the veh" as a complete station with a longwire ant and a psu?

?

good luck!

Let us know what u discover!

I installed the FC-40 in my truck after getting it at Orlando, the
857D had been in the truck for several months. Installation went OK,
tuner seemed to tune OK on all bands from 60M down. A few weeks ago
the radio suddenly quit transmitting, no bar indication. Receive was
OK. Checked 2M with wattmeter, no output, antenna analyzer said 2M
antenna was OK. Sent radio back to Yaesu, came back today. Hooked it
up, didn't work. Played with 2M antenna, it worked, then didn't work.
Discovered that when I unplugged the control cable from the back of
the radio, the radio would work. Plug it back in, the radio would not
work. Tried tuning up on 20M, had high SWR. Unplugged cable, radio
would work.
Has anyone else had this problem?
Dave, NJ4F

The local dealer finally got my money for a new one.
Now it's time to play with some wires.
Thanks to all,
Dave VA2DV

When are you going to learn not to get rid of anything?? Hee hee.

I just found out my FC 30 tuner for my 857D will work with my FT100D
as well as the FC20.Any one know what other yaesu auto tuners will
work with these two radios other than the FC 40?

Clive,

an FT-857D is installed in my car and I used the FC-40 with it
stationary. I can not find any functional differences to the FT-897.

The FP-30 is very compact, installed into to the FT-897, one piece
less to carry when you travel. The US version of the FP-30 has a
voltage selector 115/230VAC. Due to stupid european regulations of CE
marking, this switch is not installed in the EU versions. I used an
old PC power supply voltage selector switch and built it into my
FP-30. It is a very easy job to do this.
I used the gear occasionally in W4 and Canada when I am on travel.

Getting the lis in 3B8 takes 2-3 months. Contact Jacky, 3B8CF, he will
help you with the procedure. After arrival, you have to visit the 3B8
officials, pay 1000 Rupies, abt. 30US$ and you get the documents.
Never go on the air or bring your rig into the country without permission!
My callsign from Feb 2nd to 15th was 3B8/JD5HD. You can not get a
native call unless you you visit the country regularely every year, I
was told.

Cheers,

Jurgen

hi Jurgen., i'm intrigued to hear more of your experiences with the

897 and to compare with 857D....

I guess you have a key advantage with that built-in power supply.,

does it work in the US (110v?)

Also., how did you get permission to operate in Mauritius? is there

a reciprocal licence? what was yr call there?

Cheers

Hanno,

the control cable from the FC-40 to the FT-897 was a home made, 10m
long. I installed clap-on ferrites at both ends near the plugs, not
sure if they were necessary, but no problem with rf.
Plugs and ferrites were obtained from Reichelt electronic in DL.
My cable is shielded, the shield connected to GND at both ends.
Diameter, if I remeber right 0.14mm, that is the best you can fit into
the mini plugs.

闯ü谤驳别苍,
Very interesting... I also look forward to test my setup with the FC40, the
Spieth pole and one of the radios FT 857 or / and 897. During summer
vacation. Do you have extension cable for the remote controller? I think the
cable between radio an FC 40 is short. I have produced my own extension
cable 15m and in total I can use 20m with the original one. No prpblem for
the tuning finction, but some HF cause problems for some "automatic"
retuning of the FC 40.
Greetings from Munich

Betreff: [YaesuTuner] On Vacation with a FC-40/FT-897 in 3B8

Dear all,

I am just back from a vacation to 3B8, Mauritius and want to share my
experience with the FC-40:
I had a small bungaloo with space for an antenna and checked this in advance
with the hotel.
In the back there was an unused metal frame made of scaffolding tubes, about
10 by 15m in size, 3m high. I had a 12m tall fiberglass fishing rod like
tower (SPIDERBEAM), which I fixed to one of the tubes. A wire ran from the
top of the rod down to 1m above the ground, where the FC-40 was mounted. The
metal frame gave a good earth counterpoise, however I laid out some 4
radials, between 20m and 5m long. Also found a metal waterpipe nearby which
I also connected to one of the ground wires.

Tuning the FC-40 was really a charm and done by pressing the TUNE button for
1 sec. I just had to do this once for the operating frequencies. Even in
receive, the tuner follows the VFO. For tuning, the output power is
automatically reduced to QRP, so you do not cause too much QRM and high
voltages and currents in the tuner are avoided.

The FC-40 did not find a match on 160m and 30m. I think the reasons were too
low resistance for 160m, wire too short and too high for 30m, wire lenght
close to lambda/2. On all other bands, the SWR at the TRX was nearly 1:1.

I worked mostly 40m cw in the evenings and had great pile ups from Europe
and JA, also VK and US. A sked with DL worked in SSB on 20m and 15m,
reported true 59. Overall, I had 676 QSOs.

The combination FC-40/FT-897 (FP-30 built in) and a fberglass pole is my
favorite for travel. No need of finding supports for dipoles and you can QSY
on the fly.

I used a SGC-237 Smarttuner before and was not very lucky with it. It was
hard to find a working wire length and the 237 intended to re-tune in the
middle of a transmission, even if the SWR was fine. This is particularly not
good if you transmit at 100W, it can destroy the tuner. This can be avoided
with an external "SmartLock" circuit, but I think it should not be
necessary. Also, the Smarttuner does not follow in RX mode, you have to
transmit in order to tune and you better reduce the power while tuning!

I hope this is informative,

vy73, Jurgen, DJ5HD

Hi Kyle, sorry long delay - work issues in the office -

Basically, connect a balanced feedline (openwire, ladderline) but NOT
coax to the ATU. One side to the wire connector, the other to ground.

I have to tell you, this works REALLY well, and can tune up on all
bands. I don't own or have access to antenna analyser, or GDO, or
regular tuner like MFJ (YET!) but I've seen other posts about using
loops and thought I'd try it -worst that could happen is that you
can't tune, and next worst is that you burn all yr power in the tuner-

In reality, the horizontal loop *should* have impedance between 102
and a few hundreds of ohms - but if the loop isn't resonant then its
a problem. (Thats what I had to start with).

The loop is now close to 270ft (81.6 metres) but I still need to trim
it a bit - lack of time still-

I'm going to TRY and post some pictures so lets see if that helps you
see what I'm doing.

Spectrum analyser shows that there's nothing bad going on, and I'm so
far not causing QRM or QRI to anything I can find, even at 100w SSB
on any band from 80-6 (!)

I've also made a smaller version as a tuned loop on 2m to understand
the concept more - without matching, its giving swr 1:1.7 from 144-
146mhz. I'm going to make a 1/4wave 75ohm stub match during next days
to see how low the loop swr really goes when its matched properly,
and to see what the VSWR 1:2 bandwidth is. That will help me
understand whats happening in the bigger HF loop. I'm thinking of
making a tuned loop for dedicated 20m that is 2 wavelengths long and
play with it.... starting with experiments on a 6m loop that is more
manageable!


Cheers
Clive

Clive <l81ker@...> wrote: Hi folks, after moving to FINLAND where

The tuner WON'T tune this on the lower bands (but its fantastic on
20m.)

I'm going to try shortening the loop slightly to around 81m, but
before that has anyone got any advice? Why is the SWR so high for

the

tuner?

Antenna is about 5m up, and the feedline is about 4.5m.

Ground here is solid granite rock... hence the loop!
