Default Antenna for receiving WWV/10MHz: am I asking too much?

But again - this is probably not what you're really after :-)


A totaly different approach occured to me when I found that there
were no time signals readable here. WWV, CHU (if it is still around)
and their European equivalents never seem to be readable here.

The 60 kHz WWV coverage map puts me almost a 1000 miles beyond the edge
of their "weak but occasionaly useable" (my words) propigation. Someone
on another list claims his clock syncs about 30 miles north and at sea
level, but he never answered a question of too what and how often. :-(

What I thought of doing was sort of an radio to NTP interface. Access
the time information via NTP and then modulate a signal with it. 10 mHz
would be more difficult, you might be able to get 60kHz with a sound
card, or something like it. Obviously, you would not need or want
anything very strong and you may be able to couple it directly to the
antenna socket.

I know it would be cheating, but it seems like a fun hardware/software
project. You probably could get a magazine article published about it,
and maybe even sell enough boards to to offset the cost of making them.
