[time-nuts] WWV / WWVH / WWVB

[Brad Stockdale]

Hello all,

    Thank you to everyone that has helped (and some that continue to 
help) me with my GPSDO equipment post... I've got a few leads out 
there and hopefully I'll be able to get ahold of some of these units 
soon... I really am looking forward to getting to work with some other GPSDO's.

    Anyway, on to the reason for this post... I'd like to get some 
receivers so I can HEAR and USE the WWVB, WWV, and WWVH signals... I 
know that HEARING them may not be a 'normal' request, but I just 
would like to monitor the audio as well as being able to decode the signals...

    I guess the first thing to take care of is receiving the signals. 
Can anyone recommend decent receivers for these stations? I guess the 
list of frequencies would be:

	o WWVB = 60 KHz
	o WWV  = 2.5 MHz, 5 MHz, 10 MHz, 15 MHz, or 20 MHz
	o WWVH = 2.5 MHz, 5 MHz, 10 MHz, or 15 MHz

    Hmm, I just noticed that WWV and WWVH overlap... How in the heck 
do you differentiate between the two stations if they broadcast on 
all the same channels?

    Anyway, I wouldn't mind a kit type of project that would let me 
receive these signals... Maybe I'll check out Ramsey Electronics, 
Rainbow Kits, Velleman, et al. Surely one of them has kits for these 
broadcast ranges.

    Can anyone suggest a kit, or project listed online with 
schematics and parts lists, or I guess even reasonably priced commercial units?

    If I can't get radios that have built in decoders for these 
stations, I'd be happy just receiving their audio and then trying to 
build my own decoder using a PIC or something...

    Thanks for any advice.

Brad
