10m WISPY

Although both the TX and RX were built, I never got around to boxing and testing the full transceiver version. It should work, but I have not tried it. You may want to use it for your own ideas.

I have been surprised by the WSPR activity still on 10m. Back in the Es season my beacon was widely spotted most days. The same basic idea would also work on FT8. It depends on finding suitable, low cost, crystals.

Please note there was an error on the schematic: the main winding on the inductor in the oscillator collector should have 22 turns and not 9 turns.
