Josh, another frequent reporter on the SoCalMilcom group, has monitored unid air-to-air activity on another one of my spectrum hole frequencies, 233.650 MHz in Southern California. More monitoring will be need to determine which agency/unit is using this former spectrum hole.
He uncovered the user of spectrum hole 268.050 MHz. That is a VMFA (AW)-225 air-to-air frequency. They are based out of MCAS Miramar.
And he has also uncovered an apparent Navy warship working aircraft on another spectrum hole, 376.250 MHz.
Nice to see four spectrum holes solved in one day.
