I want to purchase a fc40 but need to locate it 30-40 feet away from the shack outside. What are you guys using to extend the 15 meter long cables?

Hi All. I made 148 feet wire test last weekend. FC40 is abt 10 ft from ground, 119 wire first straight up 20 feets, to highest point at 30 feets, after that horisontal and straight until it ends at 20 ft height. Radio FT897 and FC40. Just fast test: tune or not.. 1810 to 2000 kHz: Tuned 3500 to 3740 kHz: No Tune 3745 to 3800 kHz: Tuned 7000 to 7200 kHz: Tuned 10100 to 10150 kHz: Tuned 14000 to 14350 kHz: No Tune 18068 to 18168 kHz: Tuned 21000 to 21450 kHz: Tuned 24890 to 24990 kHz: Tuned 28000 to 29700 kHz: Tuned 50000 to 52000 kHz: Tuned 73s es gl de rami, oh6bi

Let's try to get this group back on track!

Is anyone else using the fc40 mobile to drive a whip? I have my FC40 mounted onto the spare tire bracket of my RAv4. It is connected to a 1/4 CB whip (only 2-3 inches of wire between.) The ground on the FC-40 is directly connected to the ground of the vehicle and all part of the vehicle and bounded together by grounding straps. Each lead into the radio, antenna control, mike, remote head,and speaker, has an RF choke on that wire. Works great on 30-6 meter, but will not tune 40m. If I add 6 feet of wire to the tip of the whip, it will tune 40m NP. Questions: 1. Anyone have this set up working on 40m? 2. Yaesu's whip for the FC-40 is 8.2 feet long, the CB whip is 9'. Should I trim the whip back to 8.2 feet? 3. Should I ground strap the spare tire itself? 4. Anyway to add 'length' without having a trail 6 feet of wire off the end? A capacitor across the FC-40 terminals? A small coil between the FC-40 and the whip? Also, 17m will tune, but compared to 30,20,15,12,10 and 6, it seems to have higher (1.7 to 1.9) than the other bands (less than 1.5 all)

Hello everybody, I'm Cedric, my call is F5PSR, I'm a FC-40 and ATAS-100 owner. I don't write here but as I spend a lot of my time on the Web (I'm moderator on others french groups) I propose to create a new group on Yahoo as it seems there is no more moderator here. Tell me if you are interested in this idea or not. If you are OK, tell me also the title you would like to have on this new group. 73 - Cedric f5psr

Hello everybody, I just started on the new group. So I have got a lot of things to do improve it is just the begining and I'm interested in any kind of ideas. The link to reach the group home page is: http://groups.yahoo.com/group/Yaesu-Autotuners I hope a lot of users would be interested in trying it. Following the idea given by Carl, KE1EJH, I called it Yaesu autotuners. And there, as here (!), we'll be able to discuss about any kind of Yeasu autotuners or automatic antennas. Please join it, try it and make you feel at home... to stay ! 73 - Cedric F5PSR

Is their a moderator for this group? PLEASE BLOCK THE SPAMERS!!!

Hi All. I sent messages to this list owner. Looks like Owners mail address is not anymore working. So I checked moderators and sent below copied message to them: --------------------------------- Hello William ! I am member of your group. I found from member list that you are the list owner. For me list is ok even not so many posts, I am a bit lazy for reading long stories... Some time ago there joined members who are intrested other things than antennas and FC40, posting "nice links". If this continues, very soon our list will be difficult to read. Maybe virus-links etc. I am kindly asking you to remove those messages and members. So that we can keep this place for our tuning infos. Summer is soon coming here and I will start again my antenna/FC40 tests. Would be nice to have this group to send my data. 73s de rami, oh6bi

what would be the best lenght of wire to cover all bands thanks Scott

Hi. It was week ago I had HAM weekend with my friend at cottage. My friend wanted to test his Icom rig in low level QRM QTH. So, I took my AH3 tuner (almost similar as FC40) to cottage for him. The 23 meter wire I found good during my earlier tests was used with AH3 and Icom radio. I dont member exactly how 23wire was working during last year tests, but there was some frequencies where FC40 didnt tune. Those FRGs were tuned perfectly with AH3. And FRGs what I never tested with FC40 was tuned well by AH3. Even the down end 1.8 MHz was tuned nicely. This FC 40 compared to AH3 has smaller coils and should be compare with icom AH4. Unfortunately I dont have AH4, just 2 pcs AH3 and one FC40. I am not telling that FC40 is not good. I try to tell that the HAM has to know his stuff and make the things working. There is NO Perfect tuner what can tune everything. FC40 is goog stuff for Yaesu radios, but have to think how to use it. 73s es GL DX de rami, oh6bi

Hi All. I made Single Line Feeder Windom Last weekend. Matching (tuner) Unit: FC40 Yaesu endfed tuner, Radio Yaesu FT897. Antenna was working against ground system, tuner at 3 m height. Antenna was inverted V position, highest point 11m from ground, hanging from feeder connection. Angle abt 120 gedrees. Wire ends more than 5 meters from ground. Dimensios at start: Longer wire 28m (91.8 ft), Short Wire 14 m (45.90 ft) , Feeder 8.2 m (26.90 ft) First I got good match all HF bands 1.8 MHz to 29 MHz except 7 MHz. After some calculations I shortened longer wire 75 cm and I got perfect 7 MHz tune, But same time I lost 3.5 to 3.6 Mhz match. After many canges I finally got this windom working at all HF bands: Dimensions at the end: Longer wire 27.35 m (89.7 ft) , Shorter wire 13.45 m (44.10 ft) , feeder 8,2 m (26.90 ft) . It was not enough time for DX testing, but local (10 to 300 miles ) QSOs at 80 and 40 m Gave similar reports between horisontal full size G5RV and this Windom. I did good experiment, easy, cheap and fast made antenna giving OK results. 73s de rami, oh6bi

Hi All. I did some testings with 119 foot wire at cottage. Radio: FT897, Ant Tuner: FC40, end fed tuner. Ground: one 20m long 16sqmm copper loop buried in ground 2 feets, two 10 ft copper/steel ground rods. Distance between each ground component abt 15 feets. all connected together with 25sqmm copper and to electrical ground. Soil conductivity not known. FC40 is abt 10 ft from ground, 119 wire first straight up 20 feets, to highest point at 30 feets, after that horisontal and straight until it ends at 20 ft height. I didnt do impedance measuring, forgot Analyser at home... Just trying to tune with FC40. 1815 kHz to 1999 kHz: perfect tuning. 3500 kHz to 3800 kHz: no tune 7000 kHz to 7150 kHz: no tune 7151 kHz to 7200 kHz: tuned (not perfect) 10100 kHz to 10149 kHz: tuned 14000 kHz to 14350 kHz: tuned 18100 kHz : band was not tested 2100 kHz to 21450 kHz: not good, some frgs tuned 24900 kHz : band was not tested 28000 kHz to 28600 kHz: perfect tuning, I didnt test higher. Next weekend maybe trying 148 feets. 73s es gl dx de rami, oh6bi

Hi All. I did excel stuff for wirelengths. feets and meters.xls and printed out 119ft and 148ft results as pdf. They are in files section.

Hi All. I got intresting link from other Yahoo group ((http://groups.yahoo.com/group/CW-Code-Warriors/) ( there is good info abt MagLoops, even some my loop photos)) Try the Group, I like it.. http://www.hamuniverse.com/randomwireantennalengths.html VE3EED has done some maths for endfed wires. List of useful lengths. I copied result to excel and converted feets to meters : ft m 29 8,85 35,5 10,83 41 12,51 58 17,69 71 21,66 84 25,62 107 32,64 119 36,30 148 45,14 203 61,92 347 105,84 407 124,14 423 129,02 Goeing to test at least one of these with FT897/FC40. At the moment I dont have good wire for 160m , thinking to test 107 or 119 at cottage next weekend. 73s es GL de rami, oh6bi

Hi All ! I have used lot of time with Magnet Loops, But now time to End Feds with FC40. I did some tests with different wire lengths. 15m , 11.5m and 8m long. I was very surprised for 15m long wire results. I uploaded file FC40 and 3 Wires to files section. Comments ? 73s de rami, oh6bi

Anyone have an extra FC-40 control cable they would sell? Tnx, Jeff/wb0m

Should I install a shunt coil onto a 102" whip feed point? (This would be between the whip base and FC-40.) 73, Damon

There are alternatives to the FC-40 tuner. I have a huge loop with an apex around 75 feet up in a tree. My SG-239 will tune all frequencies from 160-10 meters. It has operated flawlessly at my QTH with temps ranging from 10F-95F. The SG-239 is mounted about 75 feet from my rig and is fed with Davis Buryflex coax. You may want to take a look at the SG-239 from SGC. http://www.sgcworld.com/239ProductPage.html Lets look at a few reasons why you may want one. 1 It will tune a long wire with radials and loops. The FC-40 will not tune a loop. 2 The SG-239 does not need a control line for the rig but the FC-40 does. This makes installation much easier. I bought some buryable wire for 120 volts (but carries 12v for the tuner) and ran it out to my tuner which is in a waterproof electrical box that I got on ebay for $15.00. SGC makes a device that lets you run DC over the coax going to the tuner. It costs $160 so that is why I went with the buryable wire for DC. 2 It costs $195.99 from AES and the FC-40 costs $250.00. 4 The only disadvantages to the SG-239 is that it needs to be put in a waterproof box. And it will not tune 6 meters. 5 It will handle 80 watts for 100% duty cycle (CW & RTTY) but the FC- 40 will do 100. Not really a very big difference for the guy at the other end of you signal. For a real sweet antenna you could install one of these and put the SG-239 at the base of it and get coverage from 160-10 meters. http://www.dxengineering.com/Products.asp?ID=275&SecID=113&DeptID=22 My bet is that it would outperform any vertical from GAP, Cushcraft or the like. Having a tuner at the base of the antenna makes it a lot more efficient. BTW, there is a Yahoo group devoted to the line of SGC tuners. I have photos there of an SG-237 installation but it now has a SG-239 in it. http://groups.yahoo.com/group/Smartuners/?yguid=212792113&#92; Zack N8FNR _______________________________________________________ Here are the SG-239 specs.
