Eighty-five years ago this month, the July 1941 issue of Radio News featured the plans for this five-tube superheterodyne for hams. The set covered the shortwave spectrum with plug-in coils to cover 1.7 through 32 MHz, and featured a BFO for CW reception.

The circuit doesn’t look unfamiliar, as it’s not that different from a typical All American Five, but has an IF of 1500 kHz, which seems like it would leak through if you had a broadcast station on that frequency and didn’t have it well shielded.
