281.400 is a ATC frequency I believeIs A2A 281.4 or 284.1? Hearing weak transmissions on both from my location
284.100 will be the Makos in the CAP over Wilmington using their air/air (well NOBLE callsign while in the CAP).
Interesting comment on ADVICE tanker callsign by Huntress. Their information data for the CAP shows ADVICE callsign for the tanker but Huntress is calling them what shows in their call sign display which with - as Huntress stated "minus the E" so ADVIC.
Sometimes the simplest things change a whole process.
