Main Board Temporary Power Connections

Figure 24. Temporary 9v power connection and connections between switching supply and main board

Here a temporary 9v power connection is made to the main board, and the switching supply is connected
using four short #26 gauge wires. The 9v battery clip has extra wire added to it (white = +9v, black =
ground) in order to get the 9v battery further away from the main transceiver board.
Install the following parts in the following order:
- Attach the temporary power connection for the 9v battery clip as shown below. White = +9v,
black = ground.
- Attach four 2" #26 gauge wires between the switching supply and the main receiver board.
Details shown below.
- Install D1 part number SL44. Pre-tin leads for D1. It does not seem to take solder very readily.
- Install C4, C5, C6, C135 0.1 uf
- Install C136, 100 uf capacitor. Double check the black stripe polarity as shown below.
