[Elecraft] Remote KAT500

[Don Wilhelm]

Scott,

*Real* RS-232 ports (those which comply with the +/- 25 volt at the 
driver) would easily drive that 150 foot distance, but the PC based 
drivers and receivers are not likely to work reliably because the 
voltage swing is insufficient to guarantee at least +/- 3 volts of swing 
at the receiver.
The other limiting factor is the capacitance between conductors in the 
cable - that distorts the waveform.   It might work if you invest in 
good quality cable and work with slower baud rates.

I would think the loss through 150 feet of LMR400 would be low enough to 
be practical and allow the KPA500 to live in the shack.
