[Lowfer] 10 MHz OCXO for W1TAG sound card calibrator

[Laurence KL7 L]

Dog team turned up and Datum 10 MHz OXCO arrived from Paul on the same day as Dexs' - not sure what their feeding those dogs.. -  only complaint is it appears to have a small (apt) Map of Texas on the PCB print :-) Very nice unit
