Assume all radio bands, including ham bands, are monitored with at least
12-14 bit depth and recorded. Those with enough power to be heard
auditably with a good consumer or ham receiver, from a considerable
distance, are also likely to be triangulated, in real-time or later (from
the recordings) with a fair degree of accuracy.
This doesn't mean covert wireless is impossible, just that simple narrow
band modulation schemes are out and successful operation also requires very
good personal tradecraft.
All consumer and commercial radios are designed for affordable cost and
maximum interoperability using standardized protocols. Avoiding
surveillance generally requires dispensing with this path.

Or become a ham radio operator or visit your local pub once in a while.
