New England QRP Club : The Excitement is Building....

I tried to put the mounted parts so that when a nut is tightened and the part starts to turn, that the part would run into one of the walls of the tin to stop it's twisting. Also added a reverse polarity protection diode though this does cause a voltage drop. The National MF10 will run on 9 to 14 volts, the free sample Maxim MF10's will run on 5 to 14 volts and the National LMF100's on 4 to 15 volts.
