Minimal activity on 978 now. My understanding is that there is a deadline where all general aviation aircraft will have to have ADS-B. The newer technology UAT 978MHz is an alternative for aircraft that fly only below 16,000 feet. If you are in range of a ground station, there may be weather info on it as well.
The Airspy folks had that same filter made for 978MHz for me. Since I still don't have a decent antenna for 978 yet, the jury is still out on how it is working.
