Where a problem
comes in with this is in the frequency spread. The frequencies of
interest
(as requested by someone else) are as follows (all in MCs):
HNL approach/departure 118.3 269.0
HNL clearance delivery 121.4 281.4
HJR tower 132.6 340.2
HJR ground 123.8 336.4
HJR clearance delivery 121.7 380.5
Maybe a combination of multiple (2) front ends with multiple I.F. strips
would do a good job for you. Divide the needed front end bandwidth
between the two amp/mixer modules to feed the chains. My swag calculator
(scientific, wild amateur guess) divide at 250 MC. Just because HJR (for
example) uses a mid VHF frequency and a UHF frequency doesn't mean you
have to receive them both through the same chain.
Good luck with your project and have fun with it.
