Hi, Ive just bought a HackRF, but I have found RF performance is poor. Compared to a $12 USB RTL2832 SDR, it is deaf by about 32-36dB.
The tests were done with an HP 8922 test set & an unmodulated carrier at 137.5MHz. The test was the generated RF signal required for both devices to achieve the same scale level in SDR#. RTL SDR HackRF Difference Scale1 -127dBm -95dBm 32dB Scale2 -115dBm -79dBm 36dB Scale3 -105dBm -69dBm 36dB The tests were done with max gain on both devices, but with the HackRF AMP off. I have seen from posts that others have had this problem - related soldering of RF switches in the manufacturing process. Can anyone provide further details on the fix or suggest a resolution please? Thanks, Stephen
