Hi,
I'd like to build a clock radio as a hobbyist project. My ideas are to
get a Galleon EM2S receiver for WWVB time signals, hook it up to a PIC
microcontroller, and also have the PIC control a digitally tuned FM
receiver. (Yes, I'm determined to spend hundreds of dollars, dozens of
hours, and risk total failure, rather than buy a $50 Sony "atomic"
clock/radio. That's what hobbies are for, right?)
My question is, can anyone advise me on how to digitally tune a radio?
I've found lots of OEM, digitally tuned radio modules, and I'd love to
get my hands on one. But the manufacturers only deal with OEMs, and I
haven't seen anyone like Jameco or Digikey selling individual units.
Alternatively, there's several FM radio kits I could buy, but they are
tuned by variable capacitors. Is there a way to replace that with
digital electronics?
Finally, I could buy a cheapo pocket radio, but it's already got an
LCD. I doubt my ability to hack into something like that and control
it.
Any suggestions?
Thanks,
Bob Alexander
