Did some moving of equipment and so the feed has been down a while.
Everything is back up. Note: KPXE changed their freq from 122.7 to 122.725. I made the change in the Pi... but now it seems that the KPXE feed is missing altogether on the LiveATC.net website.
Hope to set up an on-field KPXE receiver next quarter. Right now the receiver is 5 miles away (at 5A2), so don't get anything once aircraft get below 750 feet AGL.
Happy holidays everyone!
