Yes, you are 100% correct about hopping the signal to South Point.
If you look at the maps on RabbitEars.info, the "Longley-Rice" maps actually do account for topography and are pretty accurate from my experience. The Longley-Rice coverage is the shaded areas, not the contour lines.

PBS appears to be back on air. Odd thing is, after rescanning, I now have two channel 10-1s and two 10-2s. For each, the first is transmitting something but it's unwatchable due to a weak signal, the second is just fine!
ETA. Just to clarify because I might not have been clear, one channel 10-1 has poor signal, the other 10-1 signal is great. Exactly the same with 10-2. I don't know enough about digital OTA channels to understand this. I can manually edit my channels to delete the bad ones, I know that, just curious if someone can explain this. I hate it when I don't understand something.

It was doing the double-10's before they went off the air as well. I just assumed it was picking up a second poorer transmitter.

I can explain!
Digital TV stations now use "virtual channel numbers", which means that a station can use any approved frequency (i.e., RF Channel 19) but will show up on your TV as their "branded" frequency (i.e., Virtual Channel 10).
HawaiiPBS actually has 3 transmitters serving this area: RF Channel 19 on the Saddle, RF Channel 28 at Hilo Bayfront, and RF Channel 41 at Kulani Cone. All 3 of those use Virtual Channel 10.
Depending on your location, you're probably picking up RF Channel 28 and also RF19 or RF41.
DId that explain it?

BTW, I'm getting two occurrences of the Channel 10's up here in Mountain View too, but both are coming in strong. I'll see if that's the case after the morning fog clears out.
If anyone is interested, we'll be doing some tests for the new Channel 32 hopefully this afternoon. That's if all goes as planned. We're low power. Signal should be best in HPP. Let me know if you stumble across it!
