Hi Peter,
You may find more activity on HF, but I'd encourage you to take a 6m antenna for intrastate QSOs. A few of us here are always interested in activating new AK grids on 6. BP64 to AP74 and AP74 should be easily achievable (ft8 or msk144), and you should have a path down toward Anchorage and the Kenai Peninsula as well. The Koyuk Airport would work well for a path to Fairbanks. I've scoped out good portable spots in Nome as well during recent visits there. If you have the time for a little adventure, you can also drive to 3 other grids from Nome - AP64, AP65, AP75 (wx and road conditions permitting).
Earlier this summer, I traveled to Fort Yukon in BP76 for a work trip, and took a radio and 6m 3-el yagi. Worked one station, John KL7HBK, but it was worth it. Lots of rare grid opportunities in AK! I think a dipole or even halo would be adequate. If you do decide to try 6m, let me know.
For HF, Donn KL7DG lives in Kotlik, AP83, and is very active. He might be a good contact.
Have a good trip!
