[OZAPRS] Igate to RF

[Jack Chomley]

Darryl,

Does not matter what 2m freq, I just took a guess :-).  Co-siting a "local" digi with one on the national frequency is something I would not do. 
In our case here, the digi on the national frequency is on a very congested site, not unlike an RF garbage dump :-) So for the digi on the secondary freq, I would be looking to a totally different site, not as high, but RF "quiet" 

73,

Jack

We the 145.175 MHz band was allocated, it was done on the proviso that we stay away from 144.39 Mhz as much as possible.
