[AMRadio] Transitron T-R switch

[BUDW2GLN at aol.com]

I have a Transitron Model T-R-3000 T-R Switch made by Transitron Inc. of  
Manchester, NH
but I have no paperwork on it..........It has a rating (as marked on the  
label) of 50-1000 watts  (?)...........Does anyone have any information or  
operating information on this little box ???..........I'm sure.that it's 
quite  old maybe made in the 40's or 50's....
