Have worked with Bert and also implemented the same DDS with a different controller but essentially the same scheme. It is working very well. Used it last night to monitor wwvb 60 Khz on the eastcoast.
Using spectrum lab could not detect and wondering of the received signal at the 1 Hz and sub Hz level. There is a DDS offset that is fixed and predicted. The signal sounded very clean. No funny or odd sounds or intermod that my ears or spectrum lab could display. The very hardest part of the project was soldering the AD5932 TSOP onto an adapter board to add real wires.
