Anyone have any experiance with real time software audio processing on a PC. Seems that if it worked as good as advertised everyone would be doing it. I'd like to try it using some kinda free or very cheap software and the PC soundcard. Ever use anything like that?

Anyone ever make a keyer circuit that just rectifies some of the input RF to drive the relay directly. That would eliminate keying transistors and associated circuitry. Would be handy to operate a remote keyed amp too. Shouldn't take much power from the input signal and most have to reduce...

Anyone have any info on this M400 linear, Class AB, 400 watt? I'm looking for the MFG info & schematics.

Anyone have any experience using just the coax shield for antenna elements? I have lots of 3/4" dia cable TV SEMI-RIDGED coax that would physically make good antenna elements for 10 & 11 meters. I don't intend to use the center conductor connected to anything (unlike in the "velocity...

Anyone thought about adding 3 or 4 diagonal radials (like on a CB starduster) 22' 9.5" long to a 5/8 wave CB antenna. Seems like you would end up with a vertical extended double zepp antenna. It would look like a giant sized StarDuster. I have been trying to figure out how to make a self...

Anyone have any experience with the Wilkinson Divider / Combiner? It seem that one divider could be used to drive two linears with one radio and then combine both amplifier outputs with another one to feed the combined power to the antenna. A few lengths of scrap coax, two resistors and...
