Pittsburgh FPS Update

I have been able to confirm a change in the Federal Protective Service frequency for the Pittsburgh, PA area. Previously they had been using 413.8750 MHz, but they have now switched to 409.4000 MHz, 103.5 PL. Reports are that Philadelphia, PA is also using this same frequency & CTCSS tone.

NNSA DC Overflights

News reports are circulating that the National Nuclear Security Administration (NNSA) is doing radiation monitoring flights around the Washington, DC area over the next couple of weeks.

These flights will be using NNSA helicopters equipped with sensors designed to monitor normal background levels of radiation. The NNSA’s Remote Sensing Laboratory (RSL) out of Joint Base Andrews will be performing the assessment for local law enforcement of D.C. area.

As far as active frequencies, the NNSA has assignments all over the federal spectrum, so searching might reveal something new. However, I'm not sure how much radio chatter there will be during these flights. You might catch the helicopter on some of the VHF low-altitude VFR aircraft frequencies, possibly using the ENERGY call sign.
