To protect the PrinterPort: Cut the trace to RCI-8719 pin 10 to 16 |
and insert 5 pcs. 4,7kW resistors across the cutted traces. |
Connection to the PrinterPort | Squelch sircuit |

To use the Scan function you need connection to the Squelch sircuit. Use a BC107 or similar NPN Transistor (Not critical) and a 4,7kW resistor and connect it to TR12 Base. Use also a 1N4148 or similar diode to protect the input fron the PTT-Switch. |
Change RCI-8719 with MB-8719.
If pin 10 is connected, cut the trace and insert 4,7kohm resistors
across.
Connect PrinterPort pin 8 to MB8719 pin 10.
Go to Setup and click on MB8719
