Re: Loop antennas fed with ladderline
I know there is a formula for it, I do not know it. All I did was
use as long of a piece that I could keep vertical which ended up being 25 foot. So do the same, run a piece of ladder line from your tuner to your delta loop and try that, you may be suprised. --- In YaesuTuner@..., Kyle N4NSS <n4nss@...> wrote: ladder line and it worked GREAT!

Hello
YES! I made a 540 foot loop for field day and fed with 450 ohm ladder line and it worked GREAT!

I let the connector dry and?the radio and tuner?work
OK.? So I am going to have to wrap up the connection better this
time.? But glad it is OK.
?
Did not use WD-40, but would have thought it would have been
OK, seeing as it is supposed to displace water.?

Thanks to all who replied.

Re: FC-40 problem

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. 73 de va3ae NJ4F wrote: Thanks for the replys from Clive, and Kyle.

Haven't had time to fix and try, but feel sure that is going to be the problem. Was letting it dry out, considered squirting WD-40 in it, but haven't yet. Will let it dry overnight and check it out tomorrow. |

Re: FC-40 problem

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.

Re: FC-40 problem
Clive T
¿ªÔÆÌåÓýhi 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!

FC-40 problem
davefuseler
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 |

Re: On Vacation with a FC-40/FT-897 in 3B8

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 --- In YaesuTuner@..., "Clive T" <l81ker@...> wrote: 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?) a reciprocal licence? what was yr call there?

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. Jurgen --- In YaesuTuner@..., "Hanno, DK3HV" <hanno@...> wrote:
