Hey guys, A fellow-radio collector from a Russian forum contacted me asking if I could provide infoprmation about the highest possible frequency America radios used before the WWII (those made before the US entered the war I think would be correct interpretation as this was the event that put some radios on hold and then changed some technology once the war had ended).
Let's make it 1939-1942 divide between pre war and 1945 post war.
The exact question is: was there 30MHz or 50MHz band before the WWII?
And when exactly we started using those?
Even more exact: could pre-war radios gop into 50MHz in principle (was the technology available, like proper tubes and such), and where there 30MHz radios before the war?
I am not that good with hostory of the US tube radios, but I am sure many folks here are.
