One for Brian???

I was wondering back when men were men and Libby Purves worked on the other
side of the mic, radio transmitters used valves.

Are there now solid state devices (big MOSFETs??) capable of producing the
necessary output power? Or are valves still used?


For VHF transistors exist around the 1500 watts mark made be Freescale
but they are put into modules the modules are connected together to make
higher outputs!..
