BITX40

Here are a couple of pictures of my BITX40. I was able to get the DDS upgrade kit from HFsigs.com, so I dropped the idea of making my own from an Arduino Nano and AD9850 DDS. The transceiver is mounted in a 1/4 inch plastic and aluminum angle stock frame. The microphone is a small plastic box with PTT switch glued in hole on side and the mic element hole on the end (so it can be used either left or right handed). I found that the speaker I have mounted to the right of the circuit board didn't produce the best audio experience, so I added a socket to the back panel to plug in an external speaker which has very good audio.  73, AL - VE3RRD
