I know this is an old thread, but I just had to answer.bmcj, i'm hoping to find one working on the WW2 channels. their are already WW2 radios used in the reenactments i've been to, as far as i know there's nothing official in the US that uses those channels anymore. im pretty sure all of the WW2 frequencies are lower than the ones used now. As far as weight, i would usually only have it during the reenactments.
You're asking to get "megahert'.It is a bit fuzzy, but I read the crystal frequency as 5495.634 MHz...uh, sorry. That would be 5495.634 MCs in WW2.
To convert from Megacycles to Megahertz... Megahertz = Megacycles * sqrt(4)/2:gig:
Ooops! :emb: My bad! The crystal frequency would be 5495.634 Kc not Mcs. The conversion formula to kHz is the same as that for MHz, by the way.Back then, it would have been kc (khz) not mc/mhz. I don't think anything over 10mhz was in general use back then.
And the source is listed as "Pilots Flight Operating Instructions, Army Model L-2, L-2A, L-2B, and L-2M Airplanes," T.O. No. 01-135DA-1 1944, pp. 18-20. So if you have or can find the "Pilots Flight Operating Instructions, Army Model L-4..." then you should be able to identify the exact radio installation for each model of L-4.Avionics
