Re: fc40 operation with ft897d

YES, you use the 8pin cat5 MIC input, and select the MIC input as

"CAT" (see the userguide). I'm doing that... you do need to configure a different way to connect the audio from the mic to MIC AUDIO IN, if you are not using DIGITAL modes, but its not a difficult thing to do either. (Simple wiring in fact). Cheers Clive --- In YaesuTuner@..., "Dave" <gm6jua@...> wrote:

fc40 operation with ft897d
Dave
Hi to the group,
I am at present thinking of purchasing an ft897d plus the fc40 atu can you tell me if it is possible to run the fc40 and at the same time be able to take a feed to my pc from the cat interface for frequency readout etc for my logging and digital mode programs ,or is there an adapter cable available that will let me feed both . Many thanks from Dave gm6jus |

Depending on your skill level you should be able to construct a longer control cable rather easily. There are others who say that the apple printer control cable works quite well. Personally I just took my existing control cable to a local commercial shop that builds cables and just told them to duplicate it but make it 30 feet longer. It works fine and was not too expensive considering the options of checking every apple shop in the city for an old cable or finding my "electrical use work glasses" to help my tired eyes for the soldering. 2. I'm hoping to use an SCS PactorIII TNC with my Yaesu 857D-- anyI have had no experience with this style of modem however I use PSK 31 with a Rig Blaster sound card modem and have no problems with my 897 and the fc 40. I see no reason for you to have any problems as long as your modem does not use the same plug on the back of your 857 as your fc40 does. Good luck and 73 Bob VA3QV/VA3RCS Thanks! |

MHz is quite normal, you are simply too close. What is your antenna and ground wire set up? Does the tuner find an match? Or do you get a "HISWR" indication on the display when you tune? Remember you need some ground counterpoise for the tuner. Best is to lay out some 5-10 wires on the ground, each about 5m long and/or connect nearby metal pipes and structures, e.g. railings, lightning grounds, whatever you find. The FC-40 works perfect if set up properly with some 10m wire and a good HF-ground. Used it on travel in 3B8, VK3, LA and had many contacts around the globe. 73, Jurgen, DJ5HD --- In YaesuTuner@..., "eptfnj" <eptfnj@...> wrote:

I would be surprised if you would make it on the HF bands to someone just 20
miles away ! Try the lower bands where there is plenty of groundwave, 160m is ideal ! The FC40 is a good little ATU, but do remember that for best results keep the wire on the GROUND side longer than that on the ANTENNA side ! Have fun ! Mike.

Attempts to use mine with wire antennas have been an exercise in fustration.? NOW they release that it will correct "up to a 3:1 mismatch" down to 2:1 or better -- not a lot of help when one is?trying to get a wire to tune from one end of the HF spectrum to the other.

FC-40 disappointment
eptfnj
i purchased a new FT-897D and FC-40 a month or so ago.
Played with long wires, verticals etc and had no contacts on HF while using the FC-40. Read the manual and followed the directions. Can't even reach a fellow ham 20 miles away on HF. The FT-897 works great on 2M & 70 cm. Having doubts about buying the FC-40 (and even the FT-897). Has anyone else had difficulties in initially setting up their FC-40? eptfnj |

Re: Digest Number 89

1. Re: Best antenna other than strainght wire for the FC-40Have you thought about trying a vertical loop antenna at all ? I have been having great success with vertical loop antennas with my SGC Auto ATU, which is basically the same as the FC40. I've got pictures, diagrams and dimensions on my website, To date I have found that the loop antennas are the best performers with the auto ATU. The problem I have found with end-fed antennas is corrosion on the ground system connections during the winter months which degrades the performance of the antenna drastically, however with a loop there is no ground to worry about ... Just an idea for you to consider. Good luck and have fun ! Mike. F5VKM |

should be ok but it is close at 102 and 98 foot so make sure your lenght is accurate not a guess. I tried 25 foot of 300 ohm twin lead and tried 25 foot of 450 ohm ladder line,,, ran one side from the "hot" side of the tuner and the other side to an 8 foot ground rod. I just wanted to try both types of line and had luck tuning using either set up. Some times I may have not been able to tune a frequency so I would move up or down the band a bit and it would tune and then just bring the vfo back to where I was and it would tune.Thats just what I did. One thing I wonder is if your ground rod is still ok and has not corroded apart under ground where it meets the salt water? I also constructed a 540 foot loop to work 160 meter for field day and fed it with ladder line as high as I could get it in the air and I was able to tune everywhere. Have fun and experiment. --- In YaesuTuner@..., kd4e <kd4e@...> wrote:

It is mostly horozontal and about 15 ft off the ground and running along the side and around the back of a masonry constructed home. The supports are an old metal eye type concrete anchor that were previously used to hang phone line and/or television cable. I have been considering a different placement. Possibly running the wire up to a peaked roof in the front portion of the home and streching the wire out (open air) to the rear of the home attaching to a chimney which would leave about 30-40 feet of the wire about 25 ft off the ground and not encumbered by the structure of the home. I have even considered relocating the fc-40 to the roof by extending the control cable but this would lengthen my ground line and shorten the antenna. Not sure if this would have a desirable overall result as the ground leg would likely then radiate. Right now the ground leg is approx 5 ft long. On second thought, this type of placement, being above ground would likely require only a few radials of a smaller length up on the roof to achieve decent efficiency. On the ground issue, I have been reading the ARRL Antenna book for insight and there is much about the radial systems but not so much on the salt water beach situation. It is mentioned that a salt water marsh is best and I guess my situation is close to that. Not so sure what else is done to effectively couple to that. Thanks for your advice and I look forward to your feedback. |

Best antenna other than strainght wire for the FC-40
n_collova
I purchased this tuner on promotion last year and strung up @100 foot
of wire and I have encountered the issues, although not all that bad, regarding the tuner not tuning all bands with any one length of wire. Additionally, the rf ground I am currently running consists of simply a ground rod driven into the earth. The earth in my area (300 tards from the beach and Atlantic Ocean)is sand with salt water approx 3-4ft down depending on the tide. A multi radial RF ground is difficult to achieve in my area due to lot coverage of my house and concrete. I suspect that since my setup is not optimum from an rf ground perspective that I might benefit from an alternative antenna such as a dipole or loop. I have heard that the tuner is quite flexible and will work with certain loops and dipoles. I also suspect that if the match is close enough that the antenna might tune all bands with the proper dipole type antenna as well and I can avoid the use of a matching transformer. Under the circumstances what would be the best alternative antennas (known to work well and tune all bands) to consider with my location being close to saltwater and not likely having an optimum rf ground easily available? Thanks in advance. |
