If the communications to/from them is in the CENELEC A band (or
similar), one may have to go to great lengths in order to have
60..77.5kHz clocks/receivers working.

I am only 500km from DCF77 (Denmark), and since they replaced the meter
with a 'smart' one, none of the radio clocks have been able to sync.

Only the phase tracking receiver, having a noise blanker, still works.

So I do not like 'smart' meters.
