The Phil-Mont Mobile Radio Club has existed since 1949. I can usually hit it using my Diamond X50A. Sometimes propagation gets weird though, and then I can access it via Allstar using my Clearnode. I enjoy checking in to the Drive Time Net weekdays at 05:00 PM local time. Philadelphia ARES also has their net on Sunday nights at 09:00 PM.
