When using my RadioShack Pro-106 scanner around 50 MHz, it picks up various signals that are basically sequences of repeating whistles and tones. Are these some kind of signaling being used on these frequencies or is it some form of interference? I'm not that familiar with amateur radio, and I wasn't able to identify them. Also, I received similar sounding signals below 6-meter HAM band which makes me question whether these are genuine broadcasts. Besides these, I haven't picked up anything discernible in these bands. There's also a lot of buzzing and other noise from 25 - 50 Mhz, which makes it tough to even scan these bands.
I've attached a few example recordings of what I did pick up.
