Marty, Jerry, Dan,
It appears to me that on the page linked by Jerry above (Reply #2), there are two distinct parts, not clearly identified as such there:
First part: There is a section above the heading "Amelia Earhart's Short-Wave Radio Never Failed" that was written and posted in January 2015, after the appearance of the Smithsonian article cited therein. (The author of that section was unaware that the Vega plane and radio equipment described in the April 1935 article were not the ones used by AE in 1937, so his comments are pretty much worthless.)
Second part: The heading "Amelia Earhart's Short-Wave Radio Never Failed" and the text and 3 photos below it are intended to reproduce the article as it appeared in the April 1935 issue of Short Wave Craft. The text and photos there necessarily pertain only to the 1935 Vega flight, not at all to the 1937 attempts in the Electra.
I'm guessing that no one has yet searched all the later issues of Short Wave Craft and other such publications for any comparable coverage of the radio equipment in AE's Electra?
