Minto,
 
as to DCF77:
my radio controlled Citizen wrist watch receives=20 DCF77 extremely reliably
every night with its built in ~2cm ferrite rod=20 antenna.
Even presently here at the Cote d'Azur field = strength is=20 indicated as "high"
(the watch indicates three=20 grades:high,medium,low).
I find this amazing.
