It could be 10 watts or as I suggest 100 or more. Depends on the range you
want to cover and what you can afford. Thats why the AM broadcast stations
are attractive, the infrastructure and power consumptions being taken care
of in the normal course of the business. Granted the CS ref and its power
Essentially it could be a national frequency distribution at very low cost
if satnav went away.
However if satnav did go away, I suspect I have other more serious concerns.
