Setup N1MM logger like this so the correct BCD appears on the YCCC SO2R+ AUX connector.
Unified Microsystems BCD10 and relay switching transistors HSD9. This will automate the system by converting the BCD output from the YCCC SO2R box and switch in the appropriate antenna. The big red switch has been replaced with 2 switches to allow independant switching from either rig when switching from a tribander plugged in on 20m to all six antenna positions on the SixPak.
