Does anyone know if a Yaesu FC40 will work with Yaesu FT 847 without a lot of rewiring? Thanks, Jon - KA9LDS

Does anyone have any information on the functions of the extra dip switches inside the FC-40. I know about the memory reset but the others must have some fuction. My attempt at a google search yielded nothing. I also noticed the RS-232 port which must be to monitor and issue commands to the microprocessor. Anyone experimented with this? 73 JR

Hello, New to the group and to the FC-40. I have owned an 857D for a few years now running barefoot into a homebrew OCF. Within the last few days I purchased the FC-40 and have strung up about 90' of wire. After looking over the FC-40 I found it a little odd that they supply you with 8X or larger coax but the connection into the unit is RG-58 sized. Internally the output wire which connects to the ceramic insulator seems a little small, sized 12 guage wire. Not trying to sound negative here, the unit works great. The only bands I cannot tune now is 80 and 30 meters. I have never been able to tune 160 on my OCf which is exciting for me. I do need to find a way to get at least 75/80 back into the mix. Anyways wondering if anyone has upgraded the input connection cable and the internal output wire size? If so was any improvement noted? I believe that the benefits would not outway the time, effort and risk but I could be wrong. Any hints on gaining 75/80 meters back would be appreciated. Thanks and 73 JR K7GFH

Hello All after long winter ! Yesterday I put my boat to sea and today goeing to summer cottage with FT897 and FC40.. If you dont know about me, just read some earlier messages from oh6bi in this group. OK, last messages during autumn I told to start testing FC40 and OCF dipole, yes I will do that. During this winter I spent 3 months in Zambia (9J2BI) and I didnt get good contacs to Europe with 23m long Wire. I installed The Wire four times to different directions to get better EU signals, but no good success, only some QSOs to Europe, none to OH. JA and UA9 where the best. Also local QRM and QRN where strong with The Wire. After that I did some tests with 7 MHz deltaloop and that was much better. QRN and QRM where lower and receiving signals better. Unfortunately work was disturbing The Hobby and not enough time for the loop. That means I will start this summer experiments with 7 MHz Delta Loop. You will see what happens.. By the way, does anyone have information how FC40 really works ? I mean would be nice to build "universal control box" same way as many has done with Icom AH4(and AH3, what I am using with IC706). Check http://www.mods.dk/ in AH4 section from AA7OL Niko Takahashi: "AH4 connetion to any Radio". Best Regards and 73s de rami, oh6bi

Hi all I am planning to install FC40 to the roof but I am worried of lightning, now FC40 is in my balcony and I am able to connect and disconnect the antenna wire from it. How is FC40 built ? Is there something to eliminate electric pulses , sure I dont mean from the straight shot. What happens in FC40 when I turn my FT897 on, I can hear some noice from FC40. When Radio is on but not "tuned" is Tuner in ByPass mode ? Does it give some extra protection if build sparking gap between antenna wire and FC40 ? 73s de rami, oh6bi

Does anyone have a FC-40 and 102-108 inch whip mounted in a RAV4? Anyone know if there is any reason to use the Yaesu YA-007 as opposed to a generic 102 to 108 inch whip? -- de k4ed aka Mark Sunderlin

Have FC-30 which meets my needs with my mobile FT-857D. The tuner can be used for receive signals. Looking for commnents for the advantages of using this option. TNX Irv N0NOB

well i have got a Ft-40 that came with the bundle of radio's that i got a short while ago, i am wondering weather i could feed a "off center dipole" with some 300 ohm feeder, something like a 33/66Ft ratio? i know it says dont use coax but if i just connect a wire i am limited to about a 20 Ft vertical. any ideas? colin KB3PNE

O.K. I have the 5mts long lindy cables. I want to be able to use the tuner from a longer distance. How should I connect the cables? I believe the lindy cables are not 1 to 1, 2 to 2, 3 to 3, etc. Can anyone help?, thanks from N1mxb, Carlos.

This is KE7GGV...Albany Oregon..I am getting a YAESU FT-707 and looking at the FC-707 Antenna Tuner....does anyone own one out there...I need any information,tips,ideas,quirks...any info will help..Thanks for your time...DE KE7GGV...73 ke7ggv@... take care www.qrz.com/callsign/ke7ggv

Hi Everyone, I'm new to this group, but not with couplers like the AH-4. I'm replacing my Icom AH-4 with the FC-40 since I've upgraded to the Yaesu FT-950. I've looked through the previous posts, but haven't read anything about what materials to use for the replacement. I already have CAT-5 cable (eight strands of wire) run to the present antenna, but it's pretty light gauge. Has anybody used CAt-5 cable for an extension? I will probably hack the current cable in two pieces and splice to the cable already there. Any thoughts? Tnx & 73, Jeff/wb0m

Hi all, my 8pin din pigtail on my FC-40 has become corroded, and I am dithering between trying to replace it with a homebrew pigtail; running the control cable from the radio straight to the connector on the board and eliminating the pigtail; or getting the part number and ordering an OEM replacement pigtail from Vertex. Is there a service manual for the FC-40 (with part numbers) available anywhere? Opinions are welcome. 73 de va3ae

Hi Folks... I have an FT-857 with a FT-40 antenna tuner... My home is located below the surrounding area and my property is heavily wooded... I installed a random wire antenna about 375 feet long oriented basically North <> South... I would be interested in anyone's experience with long-wire antennas using the FT-40 tuner... Here are some images: http://www.scalerchelis.com/g2/main.php/d/62216-2/PDRM0053.JPG http://www.scalerchelis.com/g2/main.php/d/62220-2/PDRM0054.JPG http://www.scalerchelis.com/g2/main.php/d/62223-2/PDRM0055.JPG Thanks...

Hi All ! Last weekend I tried again OFC dipole. It didnt work as well as I was thinking, Maybe I have to change position of the antenna itself but here in Finland cold season is starting (on Sat morning I found ice from my boat), this OFC project will continue when the spring comes... After disappointed to OFC testing I changed back to 23 m long wire. Before that I added one ground rod to my system, I wanted to do that because the ground gets frozen soon. FT897 was on 3,510 and I started tuning, FC40 didnt tune that, radio was telling HIGHSWR, then I changed freq to 3,530 where FC40 was earlier tuned (with the old ground system). FC40 took new settings automatically from its memory and system was perfectly tuned. Then I changed back to 3,510 and FT told HIGHSWR again, pushed tuning button, no change. After that I went up to 3,560, I tuned and everything was ok., then back to 3,510 and tuning again. Now FC40 did it well. I dont understand this, maybe FC40 needs total resetting.. 73s es GL DX de rami, oh6bi

Hi All ! In my last message I told to start new tests with OFC Dipole and FC40. Last weeks not enough time to testing but yesterday I made first test. Antenna was same as in VK2DQ writings, longer leg 38,9m and shorter leg 12,9m connected to FC40s ground. Results where not good, no tune in 80m either 40m. I think my setup needs some works.. continuing the test. Then another thing: I am not sure if this is already in our messages but I put it here: From the FT897 manual: **** MENU MODE No?059 [MIC SEL] Function: The choice of the equipment which connects to the MIC jack. Available Values: NOR/RMT/CAT Default: NOR NOR: Normal Microphone. RMT: Not available at this time. CAT: CAT system: if you are using the optional FC-30 antenna tuner, you can still use the CAT system by connecting the serial Data cable to the MIC jack. **** I have not tested this, but goeing to prepare serial cabel to see if it works. Microphone connectors down=TXD and up=RXD. Ground is same. Maybe it is possible to use the mike for speaking when connector is in CAT mode ? In my manual RMT is not available is it in use with FT897D ? Any Comments ? 73s de rami, oh6bi

Hi All ! Finally I bought FC40, I have used Icoms AH3 many yers and because of good results with it I decided to by FC40 for my FT897. FC40 will arrive to day and first I need to extend the control cable. Anyone experience ? Is it needed to be shielded or not ? How long I can make it ? How much FC40 needs Voltage and Current for the tuning. With IC AH3 I have had up to 20m long cable with wire size 2x0.5 mm. What about Ground connection ? Is it necessary to use separate ground cable between rig and tuner when the distance is longer than 5 m ? First I am goeing to test FC40 with my existing inv L antenna, vertical part 21 m and horisontal part 41 m , total 62m (204 ft). To compare existing IC706/AH3 and new FT897/FC40 with same wire + Gnd. I am goeing to use Yaesy system at my summer cottage with long wire , length more than 100 meters . Any addvises before starting the tests ? Best Regards es 73s de rami, oh6bi

My 23m wire test is done, it took 6 weekends at cottage. ( HI, I didnt do that all the time..) I started with abt 40m length wire then abt 20m then abt 11m and 15m. Finally 23m which I found best for my needs. The exact length for my wire is 23,2 m, first goeing 3,5 m straight up and then rest horisontal so that the end is abt 10m up. It works 160 to 10m but not 18 MHz. Some narrow areas at 28 MHz not working. "It Works" means that FT897 get tuned. Really working and radiation is another point.. depens of many other things. The ground is one 10 ft Copper rod and 50cm deep 20m long Copper loop. As I have earlier told that I am using also IC706/AH3 system. My opinnion is that AH3 is better unit than FC40. AH3 has bigger coils but FC40 has memories, it depens what you need, if you like more lower bands AH3 is better but if you like higher bands and you are often changing FRG then FC40 is more handy... OK now for that Coming weekend is to start OCF Dipole project. What is OCF Dipole? OCF means Off Center Feed !! There are some wery intresting writings abt OCF and after reading those I decided start OCF Project. Please check VK3APP writing: http://www.vk3app.com/index.php? option=com_content&task=view&id=14&Itemid=9 The plan is to put FC40 up instead feeder and balun. Wire will be abt 40m long, a bit longer than VK3APP is using in his article, to get it better working at 3,5 MHz(I like more CW than ssb). I did one windom test at my cottage five years ago. It was IC706/AH3 connected to 8m long vertical line. That was connected to 42m long horisontal part 1/3 from the end. As I member that system was quite good but I have lost test records .. it worked 160 to 10m, one band was not working I dont member what it was.. Best Regards es 73s de rami,oh6bi
