Careful, The format of the transmitted signals is different. A Receiver which decodes signals transmitted by MSF will not decode the signals transmitted from Colorado (WWV?) even though they both operate on 60kHz. Their dedicated Receiver IC are suitable though. They are actually manufactured by Gunter Semiconductor http://www.gsg-asia.com/ic_data_sheet/ak2124.pdf Temic also make (made?) chips U4223B. I believe that they are now part of Atmel. You will of course have to add a PIC to do the decoding. 8-) Regards Chris Carr ----- Original Message ----- From: "zantos" To: Sent: Wednesday, June 13, 2001 9:35 AM Subject: Re: [BUY] Atomic Clock Receiver > Had great succcess with this > > http://www.galsys.co.uk/galmodul.htm > HTH > > ----- Original Message ----- > From: "Michael C.
