2-Band Transmitter Schematic Updated

[NZ0I]

I just uploaded a new version of the 2-Band ARDF Transmitter schematic. The main changes are the addition of connectors to allow the transmitter to be built on three separate interconnected boards arranged in sandwich fashion.

1. The bottom board of the sandwich is the SWR Bridges and 80m Matching board. This board is optional. 

2. The Transmitter board is the middle of the sandwich. This board can be plugged into an optional SWR Bridges and 80m Matching board below. This board will accept an optional Power Supply board, and a (mandatory) Digital Interface board plugged in from above.

3. The Power Supply board is the top slice of the sandwich. This board is also optional, but if omitted you'll need to provide some other source to power the transmitter.

Layout of the boards is still in its beginning stages. So far it looks like the entire transmitter, including its LiIon battery, will fit inside the same waterproof box used for the receiver - easily held in the hand. Still targeting double-sided boards, but can switch to 4-layer if need be.
