On Thursday 1/7/10 I picked up a CBP Helo running aerial support for ground units on 169.450. I run this frequency for Wireless Mics. Mostly it was coming up as 100.0 but occasionally came up as P25-301. The helo was providing a video downlink for the ground units to record. I couldn't hear the ground units but the helo was on all day."Omaha" was heard often. They started in Edison/Woodbridge and after a fuel stop moved to the Secucus/Meadowlands area of NNJ. I was able to pick up the helo loud and clear from a fixed post approximately 40-60 miles south.
