universal qrp transmitter enclosure

I finally put the universal qrp transmitter in its own enclosure. I cut down the board to fit inside an altoids sized tin. The actual tin came from a cheap arduino kit that I picked up on discount during the final days of radio shack.


The circuit diagram for the transmitter can be found here. I made a small change from my original design. I remove the 60pf trimmer cap and the 47pf ceramic cap from the collector of the 2N2222 and added an old variable cap for tuning. The red tape on the lid is to keep the variable cap from shorting on the tin.



I added binding posts to one side of the tin and a bnc connector to the other. I also removed the original switch that I was using as a key and added a 3.5mm socket.
