[Hackrf-dev] Sensitivity

[Tom]

Thanks Tony,

 

That was one of the first things I looked at, I have just learned to live with it now.

There is an annoying tendency of the ANT500 to lose connectivity internally, if not outright convert itself to an attenuator and short. Hasn't damaged the radio and fiddling with the spring/loctite have done wonders for reception.

Thanks Stefan,

 

Just needed to confirm this with others.

 

Completely understand that they are two different devices built on different hardware etc.. etc.. but at the end of the day receive performance is the one thing that really counts when using SDR and if i can barley pick up a community radio station on 151mhz that is only 10km away from me using the hackrf with the ant500 but the signal screams in using the $12 dongle and the same antenna then that's not on.

 

If Mike ever considers a HackrfTWO please put receiver sensitivity/SNR at the top of your priority.

 

Cheers

Am I correct in saying that a rtl dongle is more sensitive then the hackrf?

 

I have done many tests with different software, sdr#, gqrx, sdr console and have tried every different gain setting, samplerates, bands, but my conclusion is that the SNR is better on the dongle. 

 

Can other members please confirm their findings comparing the two?
