It definitely has my radar up

This was heard on Morning Joe on May 17, uttered by Mika Brzezinski discussing the missing SARS reports and Ronan Farrow’s story.  It is a nice mashup of “on my radar (screen)” (considered important) and “has my antenna up” (curiosity or interest).  “Have my back (or dander) up” (get someone angry) might also be in the mix, but I doubt it considering the context (although the whole Cohen affair might be ticking her off).  A big thanks to that Malaphor Extraordinaire, Frank King, for hearing this one.  He certainly has the ears of a hawk.
