+1 to Ed's comments.
I find that during the day time short of the bc band anything below abt 7mc is pretty dead. A little before sundown and thru the rest of the day/night 1.8-7.mc come alive. Conversely from abt 12mc to 30mc is the opposite good during the daylight hours lousy at night. All of this has to do with the sun's effect on different layers of the atmosphere during the day and night.
More than likely the dial has the (then) amateur bands marked on it. 1.8-2mc,3.5-4mc, 7-7.3mc, and 14-14.4mc. The only type of signal your set will be able to reproduce properly is an AM signal. Most amateurs transmit using signal sideband and Morse code both, require separate oscillator to demodulate it to intelligible. SSB sounds like some one talking w/a tight closepin on their nose and Morse sounds like a bunch of hisses w/o proper demodulation. There is a gentlemen's agreement that AM operators operate close to 1.885kc, 3.870-3890kc and 7.280-7.295 but AM is legal to use in any of the phone portions of the amateur bands.
Ed,
Was doing some cleaning down in the basement and found three Nick Park's classics. Grand Day Out, The Wrong Trousers, and A Close Shave. Don't know if you are familiar with them. Early 1990's claymation movies staring Wallace and Gromit. Cleaver bit of animation and good fun to watch after all these years. My now adult kids watched these VHS tapes over and over when they were young.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
