one thing I always do to test new RF equipment is to try receive a commercial fm broadcast station. I don't even need to demodulate the audio, but it had better be visible on a waterfall. then I see if weaker signals (eg. a car remote) is also visible. those help rule out a few gross failures.
did someone give you an RP-SMA connector instead of SMA? are your gain settings correct? is your transmitter actually working? did someone add some extra attenuation?
