It is important to distinguish between TSA and the FAA. The TSA is in charge of airline security but the FAA deals with rules concerning what equipment can be operated on board the aircraft. Since the 1950's the FAA says FM receivers are banned on aircraft in flight. The rule still stands and has nothing to do with the TSA. Bottom line: By all means bring your scanner or ham radio just don't operate it. Don't argue with the crew. Yes, I know that modern synthesized radios are different from older receivers but the rule still stands.
If you fly a lot with radios get TSA pre-check or a Global Entry card. Saves time and trouble with the TSA. I have cleared security in 60 seconds at major airports. No taking off your shoes or belt! Some credit cards will reimburse the fee.
