Hi, I hope someone can help me. I want to swap the active and standby frequencies between the NAV1 and NAV2 radios using an external switch. I know how to make an external switch, and I can swap the active and standby frequencies within each NAV radio. But how do I get the frequencies to swap from one radio to the other? I am using XML programming.Any help appreciated, dek

Forgot to say the major problem is that the radios are written in C++ language, and I do not have a way to get into them. I'm not sure if switching is an easy thing to do in this case.Oh well, I have almost completed a new XML radio stack and will use it instead.Thanks anyhow, dek
