Guys, This rational is bogus. The PSK users have to get used to decoding one signal at a time with narrow filters if that's what is necessary. To expect to have 2 or 3 KHz free of strong signals is crazy.
Dealing with this reality puts the burden on the receiving end. No way can you control what the rest of the wold does. This isn't the Magic Kingdom. Given that PSK is a narrow bandwidth mode, why not use that to your advantage? Other modes deal with strong adjacent signals, why not PSK? You bought a K3 for its high dynamic range and high adjacent signal handling capability. Why not use it for this purpose? Of course the argument ignores all the laws of physics and propagation. I suggest you run some VOACAP prediction calculations with 25 watts and look at what you can't work with 25-75 watts. You may not be interested in working the other side of the world, but others are. PSK isn't magic. 73 de Brian/K3KO On 5/1/2012 11:46 PM, Jon Perelstein wrote: > Eric KG6MZS asked why wouldn't you run more than 70w on PSK > > Because with the close spacing of signals in the various PSK sub-bands, a > signal of more than about 50watts will completely annihilate all the other > PSK signals and make that sub-band unusable for everyone else.
