Digital readout for the original TS-520 by Mark Mohrmann, WA2FXM

Mark has written up a terrific document detailing how he added the Digital Display to his non “S”  TS-520.  There was a kit for the TS-520 back in the day to add the CAR/VFO/HET signal outputs, the TS-520S came with this option built in. Mark details how he built the interface, including the buffer amp necessary for the HET signal.  Thanks Mark!
