About ASRI® (aka ASR Inc, ARINC) US nationwide VHF network and also local VHF ASR company freqs.
Did a quick check and RR has this list that looks pretty accurate (without digging in my db.

Your best resource will be this map from ARINC or whatever they want to call themselves this week.

This is off a much broader bunch of info and maps page at
Atlantic HF Assignments that you will find very useful.
There are also ASRI company freqs for FBOs and airlines. Some arilines like American and Delta have major nationwide networks on VHF.
These freqs are usually not in public domain. The map company Jeppesen issues a tailored product for each airline. The airlines pilots in my old Navy squadrons were American and Delta so I got to see those maps of each of their VHF company networks. For instance 129.2 is a very popular nationwide assignment for American and their associated commuter airlines.
Best way to see what is active in your area is to put that scanner into search 128.8 to 132,0 MHz, find them and ID them. A lot of the voice traffic is now handled by the digital ACARS system which is in that band and also 136-137 MHz. You will hear and see some interesting stuff in Company sub bands on VHF air.
Sorry didn’t mean to get off on some VHF stuff but have had some experience in these areas thanks to some of my Navy friends, uh Officers. Hope that helps."
Looks very useful. Full kudos to Larry Van Horn!
