Alongside the RF probe Steve G0FUW provided a build document for a crystal oscillator for testing in the sudden transceiver project. This was a nice simple build and seems to be working well, I used the RF probe to check that it was working then tuned to the signal on my transceiver to verify the frequency.

As part of the QRP build group Steve G0FUW has provided build documents for a couple of pieces of test equipment. I started building this a few weeks ago but needed to get some bits – croc clips, banana plugs and finally some stiff wire. Getting the Christmas decorations last weekend I spotted some nice stiff copper wire and so finally finished off the build. It is simple and uses a multimeter for readings, but does the job.
