In addition to the frequencies above, you can try using the Aircraft service search feature in your 996P2 to find other frequencies that are not listed in the Database. Another frequency that is worth scanning is 123.450 MHz. You might hear anything from chitchat between pilots, aircraft with turbulence reports, to helicopters.
Also 123.400 & 122.750
If there is any activity in the area, 123.3 and 123.5 are used by hot air balloons and gliders.
Those are also used for aviation instruction [flight schools]
TBL 4−1−3
Other Frequency Usage Designated by FCC
| Use | Frequency |
| Air-to-air communication (private fixed wing aircraft). | 122.750 |
| Helicopter air−to−air communications; air traffic control operations. | 123.025 |
| Aviation instruction, Glider, Hot Air Balloon (not to be used for advisory service). | 123.300
123.500 |
| Assignment to flight test land and aircraft stations (not for air−to−air communication except for those aircraft operating in an oceanic FIR). | 123.400 [1]
123.450 [2] |
[1] This frequency is available only to itinerant stations that have a requirement to be periodically transferred to various locations.
[2] Mobile station operations on these frequencies are limited to an area within 320 km (200 mi) of an associated flight test land station.
I'd program these in for "just in case" or "you never know":
123.100 Search & Rescue [probably Civil Air Patrol]
122.900 Multicom
Activities of a temporary, seasonal, emergency nature or search and rescue, as well as, airports with no tower, FSS, or Unicom
122.925 Multicom
Forestry management and fire suppression, fish and game management and protection, and environmental monitoring and protection [I've heard activity on 122.925 when the county north of me has had grass fires, wildfires. etc]
I was born in & grew up in Rochester, I lived off Thurston Road between Brooks Avenue & Chili Avenue, I spent many hours scanning the aero frequencies
The frequencies haven't changed since I relocated in 1992 except for the addition of 127.325
