It is economical with components I have spent a little time optimising the design and this is my latest version. The RFC value is 33mH and may be a bit over the top for the job. It was just one that I had in the junk box. An ATU on the front end improves selectivity.
Performance is quite reasonable considering the simplicity of design.
I think other experimenters would be interested in it - perhaps it is possible to get the oscillator to drive a transistor allowing the circuit to be turned into a transceiver.
