WWVB reception indicator needed
I recently bought a couple of La Crosse Technology digital clocks that are
designed to start listening for the WWVB signal at 60 KHz at midnight, and
every hour until 6AM. I have a ham transceiver IC-765 that receives down to
30
KHz (too bad they don't mention this fact in the specifications of the
equipment) and I've been able to pick up the signal with a loopstick coil
and resonant capacitor using a source follower interface to the receiver
input, with some success, but I would like to qualify other locations in the
house besides the immediate vicinity of the ham station - - hopefully more
quickly than mounting the clock and waiting to see if it updates its
setting.
Ideally, I would like to take apart a small WWVB sync-able clock and tap
into its wiring with an LED driver so that I could see the LED flash in time
with the 1 BPS carrier modulation. Has anyone tried anything like this, and
is there a website that might show details of the conversion? I'm open to
other ways to do it as well and welcome suggestions.
Thanks,
Chuck
