Well, it was time to melt solder once more and this time I decided to build a Small Wonder Labs Rock Mite CW transceiver for the 80m band. I wanted to have a neat little qrp rig of minute power for the upcoming qrp contest.
The kit arrived from the US safe and sound with no parts missing. What a turn up for the books.
I set about soldering in the one surface mount component without problems. The secret is to use flux on the pads.
The rest of the components went in without a problem. The board was now beginning to take shape.
Next I soldered in place the wiring.
Time to sort out an enclosure. I chose an Altoids tin. All good qrp’ers seem to favour them, and for good reason. It was out with the drill for a touch of metal work.
The PCB next fitted in snugly and the wires soldered into place. I used dental floss to tie the wires up nicely.
The smoke test went well – no smoke. I then sent out a test transmission on 3.560 and received favourable reports back from Wallace VK4CBW and Tim VK4YEH. I took a DV voltage reading with my Hendricks dummy load/power meter and calculated the output of this rig to be 316mW. Nice.
