I'm trying to embrace the concept of A Hailing Channel for Packet
Radio, but I've run into an engineering roadblock. I am assuming the
"hailing channel" will be something like 440.800 MHz APRS, and the 56k
data transfer channel will be 430.9 MHz. These are 10 MHz apart. How
can I support this on a crowded site that requires a [normally low
bandwidth] intermodulation suppression panel (isolator / low pass
With the independent TX/RX connector option, is the internal TX/RX
relay preserved? I'd hate to try to implement an external TX/RX relay
with <10ms turnaround time.
