| [title] Install new diode | |
| [* icon_reminder] Make sure to test the new diode before installing it. A working TVS diode will show much higher resistance in one direction relative to the other. | |
| - | [* black] Install |
| + | [* black] Install the new diode. |
| [* icon_caution] Note the marking on the diode which indicates its orientation. The bar must be pointing ***towards the antenna***. | |
| - | [* black] Apply flux to the pads, |
| + | [* black] Apply flux to the pads, then add a thin layer of solder. If solder does not stick to the pads, you can add it to the underside of the diode pins instead. |
| [* black] Hold the new diode in place using tweezers. While applying downward force, apply heat to one pin near the solder until the solder melts and makes a connection. Repeat with the other lead. | |
| [* light_blue] Verify that the connections are good. There should be continuity between: one pin of D6 and a pin in VR3, and; the other pin of D6 and D7. |
