More and more are starting to do so with the Freescale modules - they are certainly *not* linear at 1200W from a single module. Maybe a pair will handle 1500W and be linear - I haven't seen a full se
I have yet to hear about a ham who had 120 buried bare radials underneath his two raised radials. ON4UN's original 80 meter wire 4-square hug around his 160 meter tower came close to that description
It would be interesting to see the same modelling over nonconductive "rock" earth. I suspect once the soil gets bad enough that there is essentially no electron mobility the "ground plane" (elevated

Absolutely! Treating the Sky Needle and the #12 wire as a folded dipole and using 8" for the diameter of the tower, you have a 16:1 step-up with the single #14 wire. If you made a cage of 4 or 6 wir

IMO, digital should go below 1810, AND it should preferably be a narrow band mode such as the superior JT9 mode. Unfortunately, "below 1810" is never going to fly because of the lack of access below
Mike, - Since two-thirds of the world --including North and South America-- starts at 1800, why not consider region-specific band plans? Is digital popular in other places? Put it this way - if you w
Although they do not specifically ask for an allocation on 160 meters, their principle of 15% of every amateur band located the preferred spectrum for common access across all three regions is clear
I'm sure there are some military/commercial systems that will do it but I don't believe that even the Flex are clean enough to handle the really wide band commercial data modulations. 73, ... Joe, W4
