Some time ago I bought a Pixie kit from China. It was really bought to test my building skills since my stroke. In years past this would have been trivial. The kit was so low cost that even if it had to be thrown away it would not matter.
As it turned out, it worked first time. A QSO with a local a few miles away proved all was well. The crystal supplied was 7023kHz, but a very kind person sent me a 7030kHz crystal, which is the 40m QRP CW frequency.
I see from Southgate News that the Banbury Club is running a Pixie Challenge.
