thanks QRN that is totally greek to me... that may very well need to be done...I just need pictures on how to do it!!! I do have two new final tubes for it but then I would have to nuetralize the.. something , and I have NO idea how to do that I will probably just have to sell or trade...

hi I took this yaesu FT-101F rig in on a trade ...has original box & styrofoam inserts, original hand mic, original tubes, also had a laminated "quick tune up guide".... did NOT have an 11 meter crystal in it...so I put one in the aux slot....... I do not know anythig about these rigs , so...

so how tall is the 7/8 version?? I know the sigma IV is 27'6".... so the 7/8 version would be like....34'10" ???? And you could convert a 3/4 version to a 7/8 version??? so could a penetrator 500 5/8 wavew be converted to a 3/4 or 7/8 by making it longer?? thanks sam missouri 69

hi I am thinking I may want to try a 3/4 wave ground plane... maybe the antenna specialist Sigma IV mod AV-174... anyone had experience with this antenna or know where one can be found? thanks sam missouri 69

well while I agree that my astron 20A should run my 2970dx ...it doe not... I use the astron 50A and it does fine... later sam missouri 69

go to cbtricks .com to get the specs for the moonraker 6 http://www.cbtricks.com/ant_manuals/avanti/moonraker-6_av146.pdf that should help later sam missouri 69

I prefer the 2070, mainly because of the scan feature allowing me to scan up to 10 channels all the time.. and I never use echo later sam

I have springs on both of my predator 10K antennas, so that when going in parking garages I can fold them over.... they would layback when driving down the road but I have guyed them in place....using nylon zip ties and rubber bungee cords.... they are both mounted on vans at the back left...

I have heard that the longer a boom on a beam antenna the better.... so does anyone have measurements [plans] for a long boom 5 element? I have a 31' boom 2 1/2 " dia to start with... does any one have the optimum measurements for a 5 element or 4 element beam I have measurements [plans]...

hi mike forget the "c" on the relay box..forget the "C" on the control box....only the very first SS antennas used the "C"... just run 3 wires A to A , B to B and D to D... I have two control boxes in front of me one has ABCD and the other has AB_D.. just forget about "C".... If you could...

well no, I do not believe that the control box is supplying the correct voltages.. on the readings I posted earlier two of the circuits showed "hot" on each light...activating two relays to deaden 2 of the 3 elements... our readings only agree in the "5 oclock" position... have you checked...

OK sorry I took the thread so far off topic.. working on the problem...assuming you have a 3 wire control box and relay box... when measuring the AC voltage from my control box..across terminals A-B, A-D, B-D all lights on..... O volts between A-B, A-D, B-D 1st light on [5...

I had thought of adding directors and think it is a viable option...BUT it would make it more directional, and would ,I am afraid require a rotor at that point... where as making it a 5/8 wave wopuld just increase the gain and performance... obviously would have to add length to each of the...

I have owned several of these through out the years, and I have always had 3 wire control boxes... now I have heard that the first super scanners [MR-119] had 4 wire control boxes and NO relays they used capicitors and were not very directional... the next generation with the tuning stub and...

I have a friend here in missouri that has 4 of the 6LF6 tubes for sale , new, for I think $30 each plus shipping

thank you very much sam missouri 69

glad you got that problem resolved sam

ebay is so unfair ...the same model radio is pulle and others left to sell.. sam

sorry for your loss sam
