Your best bet is to simply pick up the phone and call the station, assuming they even have a local number.

KPPX is in the process of moving from channel 51 to channel 31. As part of that process, they're installing a side-mount antenna lower down on their tower so that they can continue operating at (greatly) reduced power on channel 51 while their main antenna and transmission system is converted from channel 51 to channel 31.

I have no idea where they are in that process, the station engineer would best be able to inform you if you're able to get in contact with him (good luck with that).
