What tone on the VHF?? 99% of CBP has gone P25
The UHF is suspect, as that is generally Military Airband and AM - thinking it maybe an image from something local that you can match the tones back to...
It's been awhile, but I've heard the OMAHA aircraft here before.

Yes, using the Mil "AM" band - 350.0250 AM - Blue 3
My log shows NFM, not P25.
I did a search on-line today and found this, and much more:
In addition to these VHF digital frequencies, don't forget that the CBP Office of Air and Marine (OAM) use a variety of VHF and UHF air band frequencies:
136.3750 MHz
282.4250 MHz
308.3500 MHz
350.0250 MHz
376.0750 MHz
These frequencies are all AM mode, and not encrypted. Operations on the UHF frequencies can involve the OAM operations center at March AFB, in California, call sign HAMMER. CBP air operations have also been known to use military UHF satellite frequencies for interdiction flight operations.

Generally the CBP Air 1-9 are always $293
the likely comment about other NAC's is for/when other agencies share the same frequency., but then that makes it NOT CBP Air #
ie" 168.8375 in FLA had three different confirmed users/tags.
168.8375 $293 - was CBP Air 1
168.8375 $003 - was TSA in Melbourne
168.8375 $0CA - was TSA in Tampa
I had well over 10,000 hits on 163.6750 NFM (CBP) in the last few days.
