Last night there was no high level propagation to Alaska and only the weakest of hets on 738 kHz

Does anyone out west ever TAKE ADVANTAGE of auroral conditions and aim antennas for Latin America?
Or is it mostly gloom-and-doom since only Tahiti 738 registers in the TP sweepstakes?
One area I almost never see reports on is west coast South America ... Chile etc. Impossible except from Hawaii or Down Under or (oddly) Scandinavia?
Is Masset / Haida Gwaii far enough out and away from the Vancouver, Seattle, etc. rabble to have a shot, or would one have to do a DXpedition to the Aleutian Islands to assure enough over water path and a great enough distance from Pacific time zone pests?
On the East Coast the parallel situation is Newfoundland versus East Coast US. Brazil, Uruguay, Argentina, and other deep South Americans do better in NL than in MA, NY, NJ, etc. because the clutter of Eastern time zone domestic stations (and pest Cubans - analogous to Mexicans out west) is down at a manageable (rather than in-your-face) level.
Thoughts?

While on topic - for those of you that hearken back to REGEN receivers (We have all used one...)
Here is a bad boy that puts all REGEN's to shame.

In the pre-SDR days when I tuned my R-390A or Drake R8A to one station at a time, I found that a regenerative preselector ahead of the receiver could sometimes be a valuable tool.
The one I used was:

With those top shelf receivers the improvement was not as great as with receivers offering less selectivity and sensitivity. Car radios, portables, and cheaper communications receivers such as the Kenwood R600 really got a performance boost with the regeneration. The high-Q tuning definitely helped in urban areas where a broadband antenna of good gain would present too many strong signals at once, causing intermod / images / overload.
Users of the Kiwa Loop got similar regeneration benefits.
Now, with the Perseus, I don't use regenerative preselection much.
