Were the answers to clue numbers 10 and 12 hidden in the clues?

[Shenco]

Never saw the anagram, thanks Fiction Factory. :-)

Fiction Factory, are u looking for 10 and 12A
I have Under The Radar.

[fiction-factory]

No, i'm not doing the crossword Shenco- just trying to help out.
The RTE is definitely one crossword I would never choose to do myself. Clue 11a is intriguing but I think when I see the answer I'll probably groan.

FF. Cryptic = hidden, + under the radar = hidden
