January 1992 When is shortwave actually FM? Always, as a technical matter, since FM frequencies are in fact very short wavelengths. But in the early days, the high end of the SW spectrum as we normally define it--up to 30 MHz.--was actually home to a group of the earliest FM broadcasters.
W9XTC used to broadcast on 26050 kHz., W9XJL on 26100. And the stations got out. From the All Wave Radio "Ultra High" column of March 1938: "The power [of W9XJL] is only 80 [later 250] watts, but don't let that worry you--reports have been received from 11 countries. At this writing, 20% of the received mail has come from England!" And that's "Shortwave" in the corner of the WMC letterhead. By the way, the editor of the "Ultra High" column was someone who would become a friend to many of us: the late Perry Ferrell, founder of Gilfer Shortwave. |
