This is a low power CW transceiver that I made some years ago. It's a FOXX circuit that first appeared in the G-QRP Club magazine "Sprat". It's a simple Direct Conversion (DC) receiver and 7MHz crystal oscillator transmitter, where the crystal oscillator also doubles as part of the receiver circuit.
If you look to the right hand end of the board, there's a two pin connector for the power input, but I've lost (sorry, temporarily misplaced) the cable and connector that fits. I do have a couple of 2 pin connectors that would fit, but they are the wrong way round, red would be on the negative pin and black on the positive, and I know that I would forget and connect it the wrong way round if I used them. So, either I find the right plug and cable, or I cut back the red and black wires on the 'wrong' type and solder a length of red wire to the black tail and black wire to the red tail, so that I don't get it wrong...
The tin is an Altoids mints tin.
(For some reason, the picture is the right way round in the post, that is the lid is at the top and the connector is on the right, but if I click on the image to enlarge it, it comes out upside down!)
