'[EE]: SOT23 marked S4'

Hi Guys,
   Anyone know what transistor this is :SOT23 marked S4. It's at the front
end of a 433MHz receiver which I'm trying to figure out. It's followed by
another SOT23 P2p which I've identified as a BFR92A
I can't track down the S4 - so any help/advice would be good.
Thanks,
John

Probably a BFQ31A or BFQ31AR an NPN VHF transistor 15V 100mA
