Are you sure you are not referring to line A  which limits use of 420-430
within a certain distance of Canada?

Finding a common frequency in the 430-440 segment is more likely than
440-450.  However, if you put the backbone on the 219-220 band you would
have greater range and much less competition.

I do have to put a plug in for the UDRC-II which can provide two radio
connections one for the backbone and one for user access (or two backbone
radios if desired).
