Help!!??!!?? Our small club has to install a crank-up TV tower of about 30 feet and we do not know the manufacturer or any model numbers. We need some advice about how much concrete and rebar to use

The truth is that I'm using an MFJ-929 autotuner with my 897D and having a problem that both Yaesu and MFJ are unwilling to solve. Can someone here tell me exactly how an FC-30 or 40 works with a

Try another length (a few feet more or less as you have now) It will work I have an fc1000 by yaesu (nearly the same as the fc40) and and some setups you have to shorten or lengthen the wire that

Just bought a new Yaesu FT-950 and FC-40 Tuner. Previously, and still in the shack, is my ICOM IC-706MKIIG and AH-4 Tuner. That setup worked just fine. I just wanted a new transceiver. I stayed

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

Hey all— Has anyone built and external controller for the FC-40? If not, what about the protocol that the controller uses? Thanks, Jon w1jp

I have a full 108" whip and the lowest band I can get is 30m. I have heard of other people leveraging a capacitance hat and getting down to 80m. $0.02, Jon w1jp

I have no fc 40 BUT an fc1000 by yaesu,,,, I had some spare room in it and put a 1:4 balun on the output side .. Now with a jumper wire I can switch that balun in and can tune dipoles, loops or

Hi Ken. I tried to contact moderators and owner but no success. Not contacted to Yahoo. There is new group: Yaesu-Autotuners. It is controlled by the owner F5PSR, Cedrick. All messages has to be

In spite of owning an FC-40 I don't hang out here much. Just dropped in today to find a lot of spam and this thread which is certainly justified. I guess the list owner has gone missing? If he/she
