Having just got back into PRS radio after a two year absence I noticed a couple of the old Auckland PRS repeaters seem to be missing and one seems to have changed site. Whitford Channel 7 and Awhitu channel 4 seem to be no longer available and Bombay Channel 8 appears to be transmitting from a new site. On top of this Waitakere channel 5 appears to be only available for a few hours per day. Does anyone know what is going on. with them?
