Seems they talk to ZDC center on UHF
From my log
\BOGEY 1 CAVERT UHF (281.40000) ON 12/1/2020\
BOGEY 1 ZDC20 BACKSTONE UHF (235.6250) ON 3/1/2021
Okay I must be confused because you reported this today,,,,,
"1333- BOGEY1 and ZOMBIE1 active on 157.1000 havent heard them on UHF yet today. Trying to get a recording"
ZOMBIE1 was a USCG helo out of Atlantic City
BOGEY1 was a Robinson R44 helicopter N441BJ (USCG Auxilary) as shown in the following link
Track N441BJ flight from Atlantic City Intl to Atlantic City Intl

Neither helo exceeded 4000 feet and both returned to Atlantic City after intercept practice. Both were on KACY 124.600 after 1400 local time requested clearance back to Atlantic City, N441BJ has since departed back to its base at Harrisburg Capital City Airport KCXY.
Intercept comms were on with Huntress 228.900. I could hear the ground side of Huntress on my PA site but not the USCG helo.
I could hear the USCG helo from NJ side but not Huntress.
