[Lowfer] VHF Question.

[Warren K2ORS]

Kurt,
       I'm not sure why you are asking - are you looking for 49MHz tube 
gear? If so, there is tons of Motorola and GE land mobile stuff, some of 
it must have escaped the landfill. Also, there were lots of tube type 6m 
gear by Clegg, Gonset, Lafayette etc.

       I think the technology drove the regulations here, when rf 
transistors capable of working at 6m became cheap and available the FCC 
set aside a little used part of the land mobile spectrum for 
walkie-talkies, cordless phones, and baby monitors. It's not the other 
way around - the spectrum did not come first. As John pointed out the 
FCC makes no provision for filament power in the regulation which allows 
100mW total input to the final stage, so tubes were never a consideration.

        BTW, listened on 49MHz, it seems that there are still some baby 
monitors out there, no phones though.
