You might also look at W8JI.com where he has a pair of phased Beverages in a box-like configuration spaced apart by 1/4 wave with the termination halfway across on one end and fed halfway across the

Mike, you suggested a delta loop. It is important that if Simon decides to hang a delta loop between towers that you feed it a the corner rather than at the bottom. This should give you some vertical

An L network with a coil in series and a 500pf variable to ground might do the trick. You impedance of the antenna is to low and you need to bring it up. You can also try extending the top hat wires

Unless you use LMR 600 or Andrew heliax a cap made from standard RG-8 or 213 has its limitations. eBay has a ton of high current fixed caps very close to the value you need. Some are from Ukraine (Ru

Terry, I have learned the hard way that WD-1A, in reverse Beverage two wire mode, is down many db's compared to the forward direction. The only way to make them work equally in both directions is to

That's correct but under these rules, the VI is not DX and counts the same as a W/VE two-pointer. Navassa which is certainly rare, especially on 160, is counted as KP2. Desecheo KP5 is counted the sa

Peter, Not all countries allow FT-8 ops on 1840. JA's work split on 11908. Last night attempts to work a VU2 he was only able to legally TX around 1816 with my FT-8 being on 1844. The agreement came

This morning starting an hour before dawn 34 JA's were worked on FT-8 with a 1840/1908 split. The best path was straight west for me. I don't know how this path existed or what caused this to happen.

Please also give credit for FT-8 occupying only a few Khz'a around 1840 and compare this to a Top Band CW contest where it is at times difficult to find a clear spot from 1800 to 1950 and even higher

This could be explained by a power increase when the station's amp came on after warm up. However, a sudden 20 DB is a lot of increase to explain by any means. Maybe contacting the G station could he
