Hawaiian mediumwave stations on 650 & 940kHz.
KPRP reception was quite weak and noisy on the Kaneohe (about 10 miles from Honolulu) webSDR I was using – probably inaudible during daylight hours – and seems to be running much less than the 10kW listed.
Sister station KKNE couldn’t be confirmed on 940kHz at this time, there was only an extremely weak unidentifiable signal there. Waipahu just too far away perhaps.
Both stations have a chequered recent history with several changes of ownership, according to their Wikipedia pages at https://en.wikipedia.org/wiki/KPRP_(AM) and https://en.wikipedia.org/wiki/KKNE
