Installing SDR# on windows …

How to install SDR# on windows …

You will need …

PC/Laptop (Recommended dual core, 4gb RAM)
RTLSDR dongle
(Optional antenna / adapter. *Recommended*)
.NET Framework 4.6

DO NOT PLUG IN THE DONGLE
DO NOT INSTALL ANY SOFTWARE IT CAME WITH
If you have uninstall the software, driver and unplug the dongle.

Goto airspy.com and download the ‘SDR Software Package’
Unzip the files somewhere
Run install-rtlsdr.bat
Plug in your dongle
Run zadig.exe (as administrator)
Click options
Make sure ‘show all devices’ is selected.
In the device drop down select ‘Bulk Interface 0’
Ensure WINUSB is selected in the other drop down.
Click install
Click OK to any warnings
Run sdrsharp.exe
Select the RTLUSB dongle
Click the play icon to start capture.
Tune to a known frequency (FM station)
Ensure WFM is selected
Open the options menu
Increase RF gain, but don’t let the signal distort.
If you can hear distortion try adjusting the volume control in SDR#

Give yourself a pat on the back and get scanning!

Moving on to gqrx and linux in the next video.

Recommended SDR shopping list for up coming content …
RTLSDR – RTL2832(u) DVB-T+DAB+FM Dongle (£10-£15)
MCX MALE TO BNC FEMALE (for connecting antennas) (Approx £2)
AIR BAND (or similar) antenna (usually with BNC male connector) (£3-£10)

Hakology – Introduction to SDR

What is SDR?

S.D.R. stands for Software Defined Radio.

SDR is a combination of hardware and software used to scan/monitor/demodulate/transmit electromagnetic radio signals.

Signals?

Signals can be used to transmit voice or data.
The most common methods of transmission are FM and AM.

FM = Frequency modulation

AM = Amplitude modulation

FM, modulates the frequency of the carrier wave to transmit a signal.
AM, modulates the amplitude of the carrier wave to transmit a signal.

Both can be used to transmit analogue or digital data.

SDR setup?

You will need …
PC / laptop – Laptop preferably for portability, currently running on an i5 2.4ghz 8gb ram pretty smoothly, I did try this on an older atom processor on linux using gqrx but latency was an issue.

SDR dongle  – RTL2832U – If you want to follow along with the next few videos grab an RTL dongle you can always decided if you like the hobby enough to invest in more expensive equipment at a later date.

Antenna – You can use the one provided but its not recommended for the next few videos ill be using a cheap airband antenna I bought from ebay.

Realtek DVB-T+DAB+FM Dongle

RTL2832U – Notes: The dongle was never intended to be used for SDR but two researchers discovered the chip used was able to cover a wide range of frequencies (24 mhz – 1766 mhz) and decided to rewrite the drivers. (Antii Palosaari and Eric Fry of Osmocom) Since then the dongle has proved hugely successful with amateur radio enthusiasts.

So what can you do with SDR?

Voice, ADSB, ACARS, digital voice, AIS, POCSAG, FLEX, consumer devices, weather ballon data, HAM internet, DVB-T, GSM, GPS, spectrum analysis, weather satellites, ISS, radio astronomy, meteor scatter, FM/AM radio, RDS, DAB, RNG … probably much more!

Over the last few years lots of researchers and developers have started producing applications and code for the RTLSDR and hopefully many more projects to come as the community grows.

Keep tuned for more SDR fun stuff!

If you get bored in the meantime try googling some of the stuff I’ve listed above and start your own research / project / experiment / learning / hack / etc.

Hakology Day 3 : Blog Entry

[12.33]
Good morning hakologists, mental note go to bed earlier. Coffee time then on with some research think I’ve decided on doing a really boring video tonight we’ll see. I need more time to compile a decent SDR episode but may well do a little v-blogging today, need to get the garage sorted out. So glad to be back computering.
[/12.33]


[13.01]
Now I’m more awake I’m going to have a look at setting up my SDR rig the question is under linux on an old dual core atom or under windows on an i5 …. urgh windows.
[/13.01]


[13.37]
Major panic over located my SDR, time to get the environment setup and working … oh fun 🙂 will post some bonus twitter / WP content when I can get a decent picture of what I’m working on.
[/13.37]


[14.27]
Tea break, have some defcon vids on in the background, looking for a little inspiration and mental refreshment, realised I wasnt following Balint Seeber @spenchdotnot … well I am now.

[/14.27]


[15.13]

Well I’ve got the sdr working! Progress.
[/15.13]


[15.44]
Taking a breather for a while, need to start noting frequencies and gathering some stock footage. So far my refresher today has taught my its gqrx for linux, sdr# for windows and rtl-sdr gets installed with gqrx, need to also sort out a ‘better’ antenna so much noise in my flat. Anyway …. break time.
[/15.44]


[16.41]
Spent the last hour or so taking a ‘break’ scanning with the SDR made me remember how critical height and position are when transmitting / receiving RF. Also have the ALFA sitting next to my rig might do a little war driving for shits and giggles.

[18.00]
Social, doom4 and insurgency time.
[/18.00]


[23.26]
So my social time over ran, lol, back to the grindstone.

As promised random bonus content for the blog. Here’s a picture of an old swiss army knife and yes its seen better days and is missing a few parts/utilities its a very special one. This was my dads, dads, pen knife who I never got to meet but my dad gave me this a few years ago, dug it out tidying the other day. Will try and keep posting one original picture every so often.
