Hi James, I have had similar problems with RX sensitivity on a genuine HackRF.
These are just my views, but from the posts I have read (here & elsewhere), some of the genuine HackRFs have substantial RX sensitivity issues. I found myself in this situation - I have been trying to use the HackRF for narrowband VHF RX & found it was being outperformed by the cheap dongles. Convinced there was an issue, I did side by side testing using an RF test set (HP8920) & found there was about an 8-10db difference in RX sensitivity (measured by the receiver's ability to detect an unmodulated carrier above the noise floor). I have been able to significantly improve the performance of the HackRF with an external LNA with a low noise figure (~$30-$40 US) . This works as the first amp in the RX chain has the most significant impact on RX system noise - well it is working out so far. If you don't want to go to this trouble, I suggest the Airspy. It is RX only, but its performance is very good. Another alternative, I have found the RX performance of the clone HackRFs is substantially better than the genuine one (in my case).

Maybe it just has a really poor receive on the device. Thanks Guys James
