I had seen when those factors a long with a full moon or new moon that pulls the magnetic field more, What else helps use here in Wisconsin is the Solar Wind when it comes out of the South. All the o
I will be in San Diego, CA on Field Day weekend. Any good Field Day site to visit with some Top Band operators? I will be staying a few miles form Miramar visiting my daughter and new grandson. -- Ji
Gary you have specs and part number on those cores?? What are the specs for 160M? -- Jim K9TF All good topband ops know how to put up a beverage at night. _________________ Topband Reflector
I think your too close to tell, or just coupling into every thing around there. Knowing you I am sure you have done every thing right. Try calling CQ during day light hours and see what signal streng
Very fine Jim. What kind of gain readings are you getting now? Christman phasing is at 71 degrees? I was thinking 90 degree phasing. Whats the reasoning for this? -- Jim K9TF All good topband ops kno
I have seen some thing like those military surplus mast sections. I believe the ones I saw were made by Shakespear. I think this is the same company that made those good trout fishing rods and reels
Jim Sounds like you have a great 40M antenna for filed Day. QRP sounds like fun. All you need now is brats and beer and something to keep you warm at night. -- Right. There's some discussion of this
Just in from Spaceweather.com *GEOMAGNETIC STORM:* A solar wind stream hit Earth's magnetic field on August 5th, sparking a G1-class geomagnetic storm and auroras over several northern-tier US states
So the general concessions is that 7:5 turns was better. Do is 15:7 turns or 21:10 turns better? Whats best for 160M ? -- Jim K9TF _________________ Topband Reflector
Just try loading the 160 loop. With the other loops inside floating with not feed line to them and leave one end open. Tuning each one may get real touchy. I did this with and 80M folded dipole and w
Here is a different way to look at it. It would be like with stacked J-Poles or a beverage or just a long wire type of rhombic. -- Jim K9TF _________________ Topband Reflector
W8Ji is right with his analogy about the extended dipole. I believe the lobes on 40 and other bands for this antenna was to our advantage for East West propagation. One of our team members looked int
I have an inverted L and using a hairpin coil to match in on 160M. One coil is 6 inches OD the other is 2 inches OD. I have been thinking about making another hairpin with wire wrapped around a toroi
I am sorry, I left this out, the Hairpin is inserted between the inverted L and ground / ground radials. coils were tapped for best match, in my case about 27 ohms is the best I can do. -- Jim K9TF _
Has any one used the MFJ-907 and do what I am trying to do on 160M as a hairpin match? what range. My 6 inch coil with remote tuner in line with the tap on 160m I am getting around a Q of 80. My 2 in
