Thanks, Joe, for spec'ing out an excellent radio - I'd like one of those!

now for one additional nit...

Clocks should be RADIO-CONTROLLED (and operated independently from
radio and powered via 2 AA or AAA batteries). Two times zones should be
available, one of which should be UTC. Local time should be adjustable
for daylight-savings time (via radio control) if required; UTC should
NOT be affected by DST change. One of the clocks (including seconds)
should ALWAYS be visible, radio on or off.


Regarding the clocks, I suggest making it possible for the user to disable
the automatic time-setting based on the radio time signal.

Every once in a long while, radio-controlled clocks can mis-read the signal.
I had a radio-controlled clock radio misread the DST information, and it was
exactly 1 hour off for the next day! If you're relying on the radio to wake
you up in the morning, this could be a problem (not likely, I'll admit, but
I've seen it happen). Alternatively, design the radio controlled clock
logic so that it makes a couple attempts to read the signal, and only update
the clock if the results are consistent.
