I lived till last year in Miami which is a s far away from the 60 KHz transmitter. In the 90's Junghans came to test their 60 KHz products for that reason and as long as I lived there in my concrete slab home with steel re enforcement I never had problems receiving 60 KHz on my multiple clocks, for my Lab I used a ferrite bar. Two Junghans watches with wrist band antennas also worked perfectly. Bert Kehren In a message dated 11/10/2016 11:05:25 A.M.

Some on the list have, and I'm sure they will provide the details. Others have mentioned the potential problems with interference to other WWVB users. For starters, make sure you study and understand Part 15 of the FCC rules before you put it on the air, or you could face a nasty enforcement action. (Even if you are Part 15-compliant, you may still screw up other users' reception and get a visit from the FCC when they complain. I operate several very sensitive 60kHz receivers -- if you live in my neighborhood, I'm almost certain to be unhappy about anything you deploy.) Note that the problem with most "atomic" clocks that I've seen is actually not insufficient signal (in the wee hours of the morning, when they try to synch). It is either excessive QRM, or orienting the clock so its antenna has a null toward Fort Collins. Make sure the antenna has a major lobe toward Fort Collins (this may require relocating the entire clock or bringing the antenna out so you can orient it independently), and that it is well clear of the AC mains distribution wiring in your house and any other sources of QRM (wall warts, CFL lamps, LED lamps, etc. (this may also require relocating the clock). The typical clock using a loopstick antenna has lobes to the front and rear, and nulls to the sides. Thus, mounting the clock on the western exterior wall (for users on the east coast) is usually best. Putting it directly in front of a west-facing window may help.
