[IRCA] WBAL and IBOC hiss from WTAM

I think this is the most flagrant example of iBOC jamming yet. Tens of thousands of people in the Baltimore area depend on WBAL for news, weather, traffic and sports information. What right does WTAM have to jam WBAL? What right do US AM stations have to jam Mexican and Canadian AM stations? What right does iBiquity Corp and the FCC have to force the entire US population to but new (HD) radios? FCC -Wake up and smell the coffee! IBOC (aka AM HD) must go!
