HackRF One


In general, the HackRF is a very universal SDR to learn about all the different possibilities in RF. I chose this SDR, because it is also able to transmit with little power. Perfect for discovering the fascinating world of RF-communications.

So, here we are, my HackRF One & me… but what shall we do now? 😉
First of all, I wanted to address the known little issues of the HackRF:

Improvement of SNR (Signal/Noise-ratio)

The HackRF doesn’t have the best SNR in town, but I think, there is potential to improve this.

For a few bucks, there is a case available to shield the RF-unit of the HackRF:

The shield fits perfectly and with a few basic soldering skills, it should be no problem to apply it.

And finally, after pushing to case-top onto the frame…

I also want to replace the original plastic-case with an aluminium one, but the new case hasn’t arrived until yet.

 

Frequency drifting

To improve the accuracy of frequency and minimize thermic drifting, I plan to add an TCXO (temperature compensated oscillator).
But it’s still a plan, because Ali hasn’t delivered until now. 😉

 

….more to come….
