While listening to the new scanner (536HP) tonight, I came across two unidentified talk group. What appeared to be dispatch was t/g 738 and the unit in the field was 33130. I think this was related to a medical transport call to or from Cape Fear and Spring Harbor. As a new transplant to Wilmington it's a bit harder for me to connect the dots. I don't want to submit this for inclusion until I have these confirmed. Is anyone else familiar with these?
