I am interested in building a reciever to sync my computer with WWV. I want to receive the CHU timecode that is broadcast at 30 seconds after the minute. In brief it is a IRIG timecode encoded with a 300 baud modem and placed on the carrier. In short it seems that all I need is a simple superhet receiver and send the output to a modem and then the modem output over the serial line to the computer. Can someone point me to reference sources for schematics of the receiver and to the modem. Simplicity is the rule. The goal is to place the receiver on a 3x5 circuit card and run it off the 5 or 12v supply in the computer. thanks, -- *_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_*_* Malcolm C.

What about the clock with a serial output that heathkit sells? Marty bies@sctc.com
