Got up this morning and found...

Someone left a RADIO TRANSMITTER BC-459-A on my door step...

Its really dirty, and looks to have been started as a modification for use in th 40M band.

I gotta get to work, and that is a bummer, because I want to play with it


Update to follow later on.

If anyone knows anything about these feel free to start letting me know my starting points. I have always wanted to rebuild an older Mil transmitter and receiver anyway

Awesome!

I just began the heavy tear down of a BC-342N so I will keep an eye on this thread, also we need lots of pictures!

here is some info I was able to dig up

Ok the BC-459A was a 40 meter transmitter and part of the larger SCR-274N radio system. It it the same transmitter used in the AN/ARC5 set I posted links to above. It is T-22 in the AN/ARC5 kit. It appears to be the transmitter used in the P-38 Lighning, and is designed to run off a 28 volt Dynamotor.

There is more info here

Hopefully it will save you some time.

Thanks for the research, I honestly am thankfull.

I wont have time to dig into this till sunday.

Just a quick rundown. It looks to be in OK shape. All tubes look to be there, It is missing a cover that is in the top center, looks like someone nibbled a square hole on the lower right hand side as you look at it. It has a second antenna post added to it, and looks like there is a hole drilled for a jack on the lower left of the face.

I do have an older copy of the amateurs handbook from the 60's so I hope to find something on it in there... just gotta find it.

You might check with the ARRL because WW2 stuff was pretty common in the 50s and 60s.

Is this one of the so-called command sets? if so there should be a lot of dusty files out there.
