What's so secret in the 30-35Mhz range?
ITU says: FIXED / MOBILE

There can always be something 'secret' in most any part of the radio spectrum.

One of the things I liked to look for (along with Glenn Hauser) above 30 MHz
were harmonics of various SW broadcast stations when the sunspot cycle
supported propagation.

I'd just use a scanner capable of receiving AM hooked up to a nice hank of
wire.
