Question by CG: Shortwave Radio Bands?
I am new to shortwave radios, and I'm curious as to how bands works. I believe I have the basic idea, but I'm wondering when I'm doing an automatic scan, does the the band change on its own as the frequencies change? For instance, if I start out on the 75m band, and the radio continues to scan, does it automatically kick it in into the 60m band when it reaches 4700 khz.? Also when I switch over to SSB it goes through all of the frequencies, from 2300 to 26150, so is it operating on an entirely different system? I'm beginning to understand, but it just hasn't quite clicked for me, I may be over thinking it.

Commercial stations on the shortwave bands such as the 16m through 49m bands all use AM, amplitude modulation. Amateur Radio transmissions in the WARC amateur bands 160m through 10m use SSB and CW. There are other out-of-band services (such as trans-oceanic aircraft communications) which use either AM or SSB.

How the receiver scans is a function of the the receiver internals and without knowing which receiver you have it's difficult to advise you, apart from being trite and telling you to read the instructions which you probably have. Anyways it's more fun to manual tune as an auto tune can easily miss weak but interesting signals.
