I have a question about a band just above 30MHz

Shortwave antenna too.

Yep the classic kit, I had many.

If my dusty memory recalls correctly, the 5 channel 49mhz radios, had 49.860, .875, .890, .910, .930 and were shared with RC remote controlled toy cars, boats and planes too. Some talkies even had the morse code function.

Yes. That's what I recall. GE made single channel ones on 49.86. They were right where cordless phones were.
