IIRC, Luxembourg once declared its 1.4 MW station as "unusable" at night on 
account of "interference" from Israel (or was it Turkey ?).

The relatively low-powered ND station (10 kW ?) in Asia was sending a nice 
skywave into central Europe which caused an area of several hundred kms radius 
to be unusable on account of such skywave.

Haven't these Bozos heard of DAs?

Or, even easier, selecting the ND radiator height such that the departure 
angle minimized such skywave?

IIRC, Radio Luxembourg is on a relatively high frequency, 1440 kHz, so a 
Franklin-type radiator, one which would minimize skywave towards Europe without 
reducing local coverage in Asia, is technically feasible. One would have to do 
some simulation, but I would guess that 120 over 120 would be a good choice. 
Such a radiator would be "only" 450 feet tall, and could have an efficiency of 
about 430 mV/m/kW at 1 km.
