Depending on your location in WV you may not pick them up. The P-3 flights are in support of work being done by the Sierra Nevada Corporation facility at the Hagerstown Regional Airport (KHGR) located near Hagerstown, Washington County, Maryland. The tracks the P-3's fly, at least in the last several years, are from roughly Martinsburg WV to Chambersburg PA. Typically they arrive in the 8:30 - 9:00 pm local timeframe and depart for PAX usually around 03:00 - 04:00 local but have on occasion stayed until 06:00 local. I believe I have had them on 134.1500 (ZDC Sector 6 Hagerstown Low) enroute from PAX to the local area. They show up on my ADS-B setup.
Oops! Looks like your location is one of the local area zip codes. They are certainly not chatterboxes but do check in with ZDC arriving/departing the area
