I got the same thing when I went to Kapa'au yesterday when I took my Pro-668 (with Whistler Legacy Upgrade) out to test and sounded like a normal quiet day that side of the island, however, I did record the following TG while locked onto the Haleakala Site.
- 6502 - HFD Hamakua
- 6503 - HFD Kohala
- 6505 - HFD Ka'u (which for Whistler scanners is the Dispatch channel that picks it up when coming over the air.)
- 6512 - HFD Kohala 2 (Mainly Lifeguards using for communications between towers)
- 6103 - HPD CID West (Maunakea Ops lately)
- 6105 - HPD Hamakua (I got a couple of transmissions to come over the air)
- 6106 - HPD South Kohala
- 6107 - HPD North Kohala
The signal seemed pretty strong for it being over 43 miles away and improvement from North Kohala only having the Kahua Ranch Site. I'll be back there again this weekend to do another test with the BCD436HP and Unication G5 to see what else I can pick up.
