Windows Doesn't recognize Your HackRF device? Wrong Drivers? Try ...

 Mostly for me to remember, but Windows at times has a lapse in judgement with certain devices, DIY gadgets, peripherals that you maybe trying to connect to- for me, it was my HackRF( I have since stumbled upon a better way to start for the HackF if having driver woes- which I will cover in another post- but keep reading, since this is still good knowledge to know regarding driver issues )- no matter what, my PC could not recognize the HackRF/ or would recognize it, but as a keyboard. I required Windows to apply the correct drivers to the device so that it could be recognized for what it is... a...SDR. A HackRF.  Guessing What's Right... Making Assumptions. Getting it Wrong. So, really what we see here is that when connecting that never connected before thing into your PC, Windows is making an assumption on what that thing is, and then applying the best driver that it thinks suites that thing... From experience, and a general rule of life... "assumptions" aren't the b...

Maximising RF Range as per Texas Instruments

Making electronics such as semiconductors and pioneering advances in integrated circuits. Consistently Texas Instruments brings us innovation - in their "about me" they state this mentioning advancements "to make technology smaller, more efficient, more reliable and more affordable" – "Engineering Progress.", that is what Texas Instruments are about. Wireless/ RF Texas Instruments  or TI with their many product offerings and solutions, many of which fall into the category of being wireless- that is what our modern world is now- involving many technologies, but today we are talking more in the area of RF or Radio Frequencies. Though these technologies have advanced, and our knowledge has grown in said technologies- still, limitations exist. One of them, when talking about RF is the range that your solution needs, and realistically, the actual range possible with the technologies being utilized.  How Far Can My RF Signal Transmit? Receive? Sorry to burst you...

RTL-SDR-MANY-MUCH-ALL-MORE-EVERYTHING-BEGINNING-END-ALPHA-OMEGA

  History and the discovery of the RTL-SDR , which started out with a comfortable life as a RTL2832U , or RTL2838 - the latter, though mentioned in many components, not truly existing, rather, being named a RTL2832U (might be the reverse...). In attempts of  demodulating DAB/DAB+/FM a fella named Eric Fry put the above into the mix which further brought us the RTL-SDR More on the discovery and history of  the RTL-SDR.      Apps for the RTL-SDR Many applications and libraries which are using either librtlsdr directly or some part of the gnuradio source which is also considered as gr-osmosdr: Name Type Author URL gr-pocsag GRC Flowgraph Marcus Leech https://www.cgran.org/browser/projects/gr-pocsag/trunk multimode RX (try first!)
