This old subject may still be of interest to a few readers.
Here is a summary that does not require a subscription to read:
KLCC radio, Eugene Oregon, 90.5 MHz, 14:00 PDT on Monday July 21 2025.
Note, PDT ! In the eastern USA, you will have to subtract hours from your time zone.
I believe the program is repeated at 02:00 PDT the next day.
Of course you cannot get the radio signal where you are.

IF you’re interested, you might want to make sure the stream link works, somewhat beforehand.
At one time, i was very interested in reading about this topic. I think i deserve some of the blame for the “harmonic reception” theory supporting stories of stateside reception
of Earhart’s emergency messages,
as i posted info about the transmitter to the TIGHAR group. At one time, i had the identical model to Earhart’s radio transmitter, and i was thinking, i would do some testing with
a similar antenna and
establish some actual numbers for power radiated on the harmonics of the two channels Earhart was equipped with. But – one person has only so much time, and so i passed the transmitter
on to another
person, who is doing a much better job investigating and reporting this story than i was.
The transmitter, as i recall, has W.E. power tubes with a “side cap” as well as a plate cap. Try to find spares for those !
