This was a WWV simulator for a 2 part article the 2nd being a receiver. 73s Randall ZL2RJP -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bob Clements Sent: Wednesday, 15 September 2010 9:10 a.m. To: [email protected] Subject: [time-nuts] Homebrew WWVB TX simulator? Has anyone built / seen / bought a small simulator for WWVB? I live near Boston, and the WWVB signal is pretty marginal around here. MSF on the same frequency isn't that far away, and local noise is pretty fierce. So now and then one of my WWVB listeners (like my generally nice Junghans wristwatch) gets screwed up. The firmware writers aren't very cautious, and there's no parity bit in the code. So I have the itch to build a micro-power WWVB to set stuff with, without having to wait overnight for one or more nights. Before I dive into such a project, has anyone done/seen such a thing that I could buy or copy? I've got a WWV/WWVH simulator that I wrote (and announced) back when they were about to replace the Audichron drum machines, and I can start from there if necessary. The hardware part seems a bit more interesting, but for this purpose I don't need to derive the carrier from a GPSDO or my ancient Rb oscilator.
