I will make a few good diagrams showing the connection to APM1/2 shortly.

Thanks. I think I've figured it out that far.

I have the two RFD900s powered up and am getting a solid green light. I assume that means the two radios are linked up.

When I jump the UART 0/2 pins from the APM to the RX/TX ins on the RFD (pins 7 & 9) I get a blinking red light, I assume this means I'm sending data.

On the RFD that is connected to my laptop I have a solid green light. and the data/activity light is blinking, but it is very very dim compared to the other modem connected to the APM.
