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 are not. 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. Regards Paul WB8TSL
