On today's menu: DRM

Stumbled across some stuff, making me think I'd need to design and build a DRM-receiver. First ideas evolved; the design will be using (pulled) crystals and logic ICs.

Frequencies the receiver should be receiving, standard crystal frequencies provided:
  • 3995 kHz (BBC/DW) - 4.000 MHz
  • 6130 kHz (BBC/DW) - 6.144 MHz
Other frequencies be reached by standard crystals:
  • 3965 kHz (RFI) - 3.9321 MHz
  • 5995 kHz (Radio Australia) - 6.000 MHz
  • 6015 kHz (TDPradio) - 6.000 MHz
  • 9850 kHz (Radio Prague) - 9.8304 MHz
  • 11995 kHz (RDP Int.) - 12.000 MHz
For the fun of it, frequencies reached by standard crystal frequencies divided by two:
  • 1008 kHz (Economic. Ch.) - 2.048 MHz
  • 1548 kHz (DW) - 3.0721 MHz
The plan, for now, is to build something for the first list provided in this post.
