I recorded the attached clip last night on one of the known test frequencies for the R-4807A air space, 375.800MHz between 9:48pm and 12:37am. The test article, an F-117 from TTR, callsign Night 20 was doing a number of test runs using different modes referred to as "Tango 1-6". The term "Tango" was also used in a test last year attributed to the B-21 program. The test controller at TTR used the familiar call sign "Ramrod". Air space controller is Blond Girl. Refueling was provided by a tanker using callsign "Sierra 98" (tail #62-3568) on a different frequency.
