XTAL FILTER IN to XTAL FILTER OUT || 12 Volt to 12 Volt || Connections to BLT

____Connect the 75 ohm coax that comes from XTAL FILTER OUT on Board 1 and connect it to XTAL FILTER IN on Board 2.

At the Xtal Filter IN I used an RCA Phono connector. When doing a lot of testing, the RCA Phono connector made it very easy to move the board out of the way.

Also, small coax cable can be soldered to the loops at both ends. Use a little extra length so the board can be flipped back out of the way when needed.

____Connect the 12 Volt and the Ground BOLD squares on Board 1 to the 12 Volt and Ground BOLD squares on Board 2.

Connections to the Blue Lightning Transceiver

____Connect the 12 Volt and Ground BOLD boxes on Board 1 to a connector for a 12 volt power supply. I used an RCA Phono connector at the side of Board 2 to connect power.(Connector not provided in the kit) Board 2 has an open ground plane to solder on.

____Connect the Antenna BOLD square on Board 1 to an Antenna connector. If a transmitter with an Antenna switch is used (like the WA2EBY), the Antenna will be connected to the switch. (Connector not provided in the kit)

____Connect the Speaker BOLD Square on Board 2 to a Speaker connector. A connector can also be soldered to the side or back of Board 2 on the ground plane. (Connector not provided in the kit)

If the transmitter is placed on a bottom board, having the connectors for the 12V Power and Speaker placed on Board 2 makes more room for the transmitter and Low Pass Filters on the bottom board.
