Hi. Could someone out there please tell me what frequencies transmit best over AC power lines. Are there any IC's on the market to interface to the AC power lines ? I was thinking of putting together a current carrier modem so I could zap files from a computer in the basement to one upstairs without tying up the phone lines. Any help would be very much appreciated - (no - I can't afford a commercial unit) Thanks in advance /Leonard

I remember seeing such a thing (very simple, but probably slow - "trickle" more than "zap" variety) in an issue of Byte about a year and a half ago, in Ciarcia's Circuit Cellar dept. (not to be confused with a fancy bells-and-whistles $400 modem he described more recently.) Next time I'm in the library, I'll try to find the exact reference. Sorry, couldn't mail the above - your site is not in our /etc/hosts. ---------------------------------------------------------------------- >>>>---------------> khayo@math.ucla.edu
