All, Today in the late 1600 hour (EST) caught Omaha 48L (Eurocopter N4048L, New York) working with Philadelphia Sector (165.2375). He wanted Sector to inform A1021 in the Command Post to come up on frequency A6 (unidentified) in the clear. None of the Customs freqs in my scanner banks were active after that.
