I live two miles from WWV. I get accurate time on my atomic clock, my

Almost everything in life can be overdone, except for K2 Mojo. I have

I did want a Gee-Whiz factor for the shack. At Dayton last year I bought
my very first MFJ product, a Model 121 clock. This is a large Dual LCD

Yep. Several ops mentioned modes I don't use .
I often use the propagation beacons at 20 meters and down, but my PC clock
is synched to NIS through the internet connection, so it's always "dead on"
for that purpose.
Is it okay if I buy an atomic clock some day for the 'Gee Whiz' factor ?

Ron:
Probably, unless one is using some very exotic mode such as Coherent CW,
millisecond synchronization is not actually required for ham operations.
However, there are some fairly routine operations in which sub-second
resolution is a necessity and not a luxury. These include the

For some digital modes, you have to know the time to the second or close to it,
as some digital sequences are 15 or 30 seconds long. Even for typical SHF
terrestrial work, the common adage is "You call on the odd, I call on the
even." There are 60 and 30 second sequences on that too I believe.

To bad they don't make one that you can interface your existing GPS

I notice that you were associated closely with the GPS system at one time.
Do you know of a source for a GPS clock - that is to say, a clock only,
with a fairly large digital display, preferably 24 hours, settable lo

Why not just use a cheap GPS receiver instead of a WWVB receiver. It should
work anywhere in the world, and give time keeping accuracy better than 1
microsecond relative to UTC. Most of the time location accuracy is around
10-30 meters, so equivalently the time error at a GPS receiver is 35 to 10

Dave my house has aluminum siding and my atomic clocks work just fine.
There are some areas in North America where the signal may not be strong
enough. Anothing thing you might try is to wind a coil around the clock in
behind and run an open lead so that there is coupling to the clock antenna
