Per Cumbria UK Global Tuner remote:
9/2/11, 0020-0035z, 6930-6935 kHz: Loud buzzing reminiscent of jamming heard over some clandestines. But, per wunclub logs, may have been STANAG 4285. When comparing what I heard with various online recordings it did indeed sound most similar to STANAG 4285. Was inaudible here at home and barely audible via Nova Scotia remote tuner.
