Forgive me for resurrecting this thread, but I have been trying to ID this station and still am unable to nail it down.
I have gathered more information since original post. These transmissions are DMR with negative polarity, color code 13, sometimes encrypted but mostly not.
The signals are too weak for me to decode voice but the aforementioned information does appear when using DMR decode as well as DSD+.
Can anyone else copy this signal in the southeast Pennsylvania area?
Maybe someone with a better antenna running a tapped scanner and appropriate software can get a good copy and provide more information on this rogue signal.
