[Elecraft] Re: radios on networks

[Larry Phipps]

I have been controlling my radio, rotator, SteppIR, and a commercial 
relay/ADC board over my LAN and internet for 5-6 years now. I now also 
control/monitor my own LP-100 wattmeter and LP-Remote relay/logic/ADC 
board over the network. I wrote an article several years ago in QST on 
how to do this, and there is more info on my website about the process. 
The hardware is  not very expensive, especially if you pick it up on 
eBay, and the software programs are mostly free downloads on my website 
and others.
