| Title | Letter from [Alan Archibald Campbell] Swinton, to Sir Henry Jackson |
| Creator | Swinton; Alan Archibald Campbell (1863-1930); British electrical engineer |
| Date | 31 March 1921 |
| Description | Returning Jackson's notes of experiments with a shielded D. F. coil, commenting on his interest in the topic [enclosures not present]. Does not understand Jackson's explanation of the heterodyne effect as he does not see how incoming waves of any given frequency can excite waves of another frequency, even in a circuit which is out of tune. |
