[Hackrf-dev] Duff Samples ?

[Simon Brown]

And the good news - forcing a narrow bandwidth filter clears it up, looks
like I'm being clobbered by military radar from time to time.

 

Panic over, move along please, nothing to see here.

Hi Mike,

 

First - as a developer I must say 'thank-you' for a very easy to use API
with clear, simple examples. It took less than one day to get Stereo FM
reception working, just a shame about my tinnitus L.

 

Anyway this morning I finished the hackRF implementation in my own Windows
code. At 8 Msps sample rate it's absolutely fine, doing a grand job. With
any higher sample rate (even 10 Msps) the data flows at the expected rate,
but the samples aren't as 'good'. The FFT shows this - the same signals are
present but not as clear, demodulating Broadcast FM is very muffled.

 

I've checked my code left, right & center and am sure I'm not doing anything
stupid (I can really screw up code without trying). I tried two hackRF
devices, both returned identical results.

 

Am I losing the plot?
