A few recommendations and suspect others will chime in too....
Load the ARTCC (FAA Centers) Freq for Indy and Cleveland Centers
Look up the Radio Reference Military Air (Mil-Air) Wiki for Norad, AWACS and TACAMO freq' and also you might load in USAF Tanker freq too as migh have Air Refueling in the area or to/from your area. All freq are in "AM" mode with few exceptions (SATCOM is NFM)...
I posted the Dec 2013 AR Tracks in the Military Forum as USAF Air Refueling... so you can see whats AR area are near and likely pick up...The Tankers/Receivers will call the ARTCC to start AR work as will Norad as deconflicting airspace.
If AWACS is up you can clearly hear them vector fighters and call "NOR-TRACKS" at times to ident a specific target.
Load Civil Air Patrol Freqs as sometimes they fly the Low & Slow profiles for Air Intercept exercises too...
Check NOTAMS for both above FAA Centers for AR Tracks, MOA and Restrictions within ARTCC Zones.
Hope this helps and please advise what you find...
