81. Re: Topband: Testing FST4 on 160m (score: 1)

I'm not understanding the time setting on FST4. Does the station calling CQ set the time duration of FST4 and the receiving station automatically detect that time setting and mimic it, or do both sta

I would add to the conversation that you must know what type of insulation is on the wire. I picked up about 5000 ft. of 20 ga. wire at a hamfest and I used it to put down about 70 radials on my shun

Jim, I used to go to Crown in Elkart and talk to the (old) owner, I can't recall his name, but this was at least ~35 years ago or more. He would often buy high end audio equipment, try it out, and th

It's quite possible that the addition of a beam at 60 ft. could cause capacity hat effect changing the current flow in the tower. It might be worth modeling this. Jim - KR9U _________________ Searcha

Is your tower detuned for 160 meters when in receive? My first thought is that the shunt fed tower resonance is interfering with your HiZ Vertical array. Jim - KR9U <<<I have 600 ft reversible BevFle

Author: "James Wolf" <jbwolf@comcast.net>
Date: Thu, 7 Dec 2023 15:12:36 -0500
I believe that it greatly depends on if the tower is closely resonant to 160 meters. In my case, the K9AY array is about 150 ft. from the tower. I tried detuning my tower and even though the tower is
