ABOUT RTL-SDR
What is RTL-SDR?
RTL-SDR is a USB dongle that can be used as a computer based radio scanner for receiving live radio signals in your area (no internet required). Depending on the particular model it could receive frequencies from 500 kHz up to 1.75 GHz. Most software for the RTL-SDR is also community developed, and provided free of charge.
The origins of RTL-SDR stem from mass produced DVB-T TV tuner dongles that were based on the RTL2832U chipset. With the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) it was found that the raw I/Q data on the RTL2832U chipset could be accessed directly, which allowed the DVB-T TV tuner to be converted into a wideband software defined radio via a custom software driver developed by Steve Markgraf. If you've ever enjoyed the RTL-SDR project please consider donating to Osmocom via Open Collective as they are the ones who developed the drivers and brought RTL-SDR to life.
Over the years since its discovery RTL-SDR has become extremely popular and has democratized access to the radio spectrum. Now anyone including hobbyists on a budget can access the radio spectrum. It's worth noting that this sort of SDR capability would have cost hundreds or even thousands of dollars just a few years ago. The RTL-SDR is also sometimes referred to as RTL2832U, DVB-T SDR, DVB-T dongle, RTL dongle, or the "cheap software defined radio".
There are now many other software defined radios better than the RTL-SDR, but they all come at a higher price. Currently we think that the Airspy ($169) and SDRPlay ($99) SDR's are the best low cost RX only SDR's. There is also the HackRF ($300USD) which can both transmit and receive.
What is Software Defined Radio?
Radio components such as modulators, demodulators and tuners are traditionally implemented in analogue hardware components. The advent of modern computing and analogue to digital converters allows most of these traditionally hardware based components to be implemented in software instead. Hence, the term software defined radio. This enables easy signal processing and thus cheap wide band scanner radios to be produced.
What are some RTL-SDR Radio Scanner Applications?
The RTL-SDR can be used as a wide band radio scanner. Applications include:
- Use as a police radio scanner.
- Listening to EMS/Ambulance/Fire communications.
- Listening to aircraft traffic control conversations.
- Tracking aircraft positions like a radar with ADSB decoding.
- Decoding aircraft ACARS short messages.
- Scanning trunking radio conversations.
- Decoding unencrypted digital voice transmissions such as P25/DMR/D-STAR.
- Tracking maritime boat positions like a radar with AIS decoding.
- Decoding POCSAG/FLEX pager traffic.

Note that not all the applications listed may be legal in your country. Please be responsible.
What is the RTL-SDR frequency range?
This is dependent on the particular tuner variant used in the dongle, and the particular implementation. Some dongles, like our RTL-SDR Blog V3 also utilize the direct sampling mode which can enable reception below 28 MHz.
TunerFrequency rangeElonics E400052 – 2200 MHz with a gap from 1100 MHz to 1250 MHz (varies)Rafael Micro R820T/224 – 1766 MHz (Can be improved to ~13 - 1864 MHz with experimental drivers)Fitipower FC001322 – 1100 MHzFitipower FC001222 – 948.6 MHzFCI FC2580146 – 308 MHz and 438 – 924 MHz (gap in between)
Table Source: Osmocom
As you can see from the table, the Elonics E4000 and Rafael Micro R820T/2 dongles have the greatest frequency range.
What is the RTL-SDRs sample rate?
The maximum sample rate is 3.2 MS/s (mega samples per second). However, the RTL-SDR is unstable at this rate and may drop samples. The maximum sample rate that does not drop samples is 2.56 MS/s, however some people have had luck with 2.8MS/s and 3.2 MS/s working well on some USB 3.0 ports.
Dropped samples are okay if you are just visualizing the spectrum, but will cause problems if you want to demodulate/decode signals.
What is the RTL-SDR's ADC resolution?
The native resolution is 8 bits, but the Effective Number of Bits (ENOB) is estimated at ~7. Decimation in software may raise this value.
What is the RTL-SDR input impedance?
Since these dongles are intended for TV, most dongles will have an input impedance of approximately 75 Ohms, although it is unlikely to be exactly 75 Ohms over the entire frequency range.
Remember that the mismatch loss when using 50 Ohm cabling on a 75 Ohm input will be very minimal at less than 0.177 dB.
The 75 Ohm impedance for the R820T can be checked on the datasheet which can be downloaded here.
However, newer dongles that come with SMA connectors will be 50 Ohms.
What are the minimum PC requirements?
Generally, at least a dual core processor of some sort will be required for most general GUI based software defined radio software. Command line tools and ADS-B decoders may work with less powerful hardware. Single board PCs like the Raspberry Pi 3, and Android mobile devices can also run several applications.
What dongle should I buy?
The cheapest, most common and generally best performing dongle at the moment is the Rafael Micro R820T2. It can be bought for about $20 USD.
The Elonics E4000 used to be the most common, but Elonics has closed and ceased chip production, making the E4000 rarer and much more expensive these days. Note that there seems to be a misconception that the E4000 is better than the R820T2 because it costs more - this is not the case, the increased cost is only due to its rarity.
The R820T2 is generally regarded as having better performance and sensitivity for most interesting frequencies compared to the E4000. For ADS-B, the R820T2 is much more sensitive at 1090 MHz. There are now also the R820T2 dongles, which offer increased sensitivity over the R820T. For these reasons, the R820T2 is currently the recommended dongle, unless you need the higher frequencies that the E4000 provides and are willing to pay a premium price.
Be careful when buying a dongle as certain sellers tend to misrepresent their devices (knowingly or unknowingly) as having compatible tuners, when in fact they may send out a device with an incompatible tuner. Also be wary when buying E4000 dongles from auction sites as there are many dodgy sellers incorrectly advertising R820T2 dongles as the rare E4000.
See our RTL-SDR store page for more information about where to obtain dongles from reputable sources. We now sell our own "RTL-SDR Blog V3" dongles which come with several key improvements for the SDR crowd and we recommend these for users who want to mainly use their dongle for SDR.
I already have a USB TV Tuner, is it Compatible?
If your TV tuner contains an RTL2832U chip it is probably compatible. If it does not contain this chip, it is not compatible. A list (somewhat out of date) on compatible and incompatible tuners can be found on this reddit wiki page.
Who owns RTL-SDR?
No person or company owns RTL-SDR and all it's supported software and hardware in it's entirety. However, it was the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) who first discovered that certain TV dongles could be used for SDR. Osmocom in particular developed the first RTL-SDR driver which was released as open source.
Since then RTL-SDR has become a community based phenomenon. Certain companies such as us at RTL-SDR Blog have taken it upon ourselves to produce our own flavor of RTL-SDR dongles that perform better than the standard TV dongle. But none of it is possible without the wider community development behind all the free software.
People Behind RTL-SDR:
Original pioneering discoverers: Antti Palosaari, Eric Fry and Osmocom. In particular Steve Markgraf from Osmocom who developed the first driver.
Hardware Sellers: Chinese factories producing and selling generic TV dongles. Sellers of RTL-SDRs improved for SDR use like RTL-SDR Blog.
Community Software/Hardware Devs: Anyone who has created software for the RTL-SDR, or has discovered and documented a hardware hack for the RTL-SDR.
Community Bloggers: RTL-SDR Blog, and other bloggers/content creators who write and popularize RTL-SDR applications.
Wider Community: Anyone using RTL-SDRs.
What is RTL-SDR Blog?
RTL-SDR.com (RTL-SDR Blog) started as a place for us to upload our RTL-SDR tutorials and to curate all other RTL-SDR related content onto a single blog. Since its inception we have continued to expand and have written many tutorials, written a guide book and started the signal identification wiki.
A few years ago we decided to create our own RTL-SDR dongle hardware that has significant improvements that benefit SDR users. Since then we've continued to improve our RTL-SDR hardware and are now at the V3 dongle.

How to receive weather satellite images
HF Weather Fax Schedules
Introduction
It's possible (and quite easy) to receive weather charts and satellite images, using nothing more than your computer and the appropriate radio. This short tutorial shows you how to do this using your Macintosh computer.
I also have apps for the iPhone and iPad as well as Android
Surface Analysis Chart from NOAA/NHC
This first image is a Surface Analysis Chart. It was transmitted from the NOAA/NHC from the USGC in New Orleans, Louisiana. Five USGC stations transmit weather fax at various times throughout the day. Take a look at the HF Weather Fax Schedules further down in this document for time and frequency information.
Weather satellite image re-transmitted over HF
This is a weather satellite image that was re-transmitted over shortwave radio. It's much easier to receive these re-transmissions than it is to directly receive the image from the satellite.
How Weather Fax is transmitted over HF radio
A fax is transmitted line by line, typically at a rate of 120 lines per minute, or half a second per line. For example, to send a weather chart, you would start in the upper left corner. You would send the value of that pixel (dot), black, white, or perhaps a shade of gray. Then you would move over one pixel to the right, and send that pixel, and so on, until you reach the edge of the chart. Then you'd move all the way back to the left edge, and move down slightly, one line, and repeat the process.
Each pixel is converted into a certain audio frequency or tone. By convention, a tone of 1500 Hz represents black, 2300 Hz represents white, and frequencies in-between represent shades of gray. So if you listen to a fax transmission, you'll hear the different tones as each pixel is present. For example, listen to a chart with mostly white background being sent. You'll hear mostl the high pitch 2300 Hz, and some lower (1500 Hz) blips as each black pixel is sent. When a horizontal line is sent, you'll hear a long half second burst of 1500 Hz, since the line is all black.
(A note for the purists: OK, The above was a simplification. In reality, the transmitting station frequency modulates the carrier. That is, when a black pixel is transmitted, the carrier shifts down 400 Hz. When a white pixel is transmitted, the carrier shifts up 400 Hz. For a medium gray pixel, it stays on the assigned frequency. This is how most fax transmissions are actually made. But, since we're tuning it in with a SSB receiver, it sounds to us as if the station is transmitting a variable frequency audio tone. Actually, the two processes are identical. But, this accounts for the confusion regarding what frequency to tune the radio to in order to properly decode the fax transmission. Different stations list their frequency in different ways. It is important to remember that what's really important is tuning the radio so that a black pixel produces a 1500 Hz tone, and a white pixel produces a 2300 Hz tone. )
How to receive weather fax images
In order to receive and decode fax images, you'll need an appropriate radio and antenna, and a cable to connect the audio output of the radio into your Macintosh computer's microphone jack. You'll also need appropriate software to display the images - such as MultiMode. MultiMode decodes weather fax and satellite images on your Macintosh, without the need for extra hardware.
The only requirements of the radio are that it tunes the frequency ranges of interest. A general purpose communications receiver tuning 0-30 MHz is ideal, SSB marine radios may also be used, if they can receive the frequency bands of interest. The radio must be able to tune in USB (upper sideband) mode. Inexpensive portable radios are not as satisfactory, although higher-end units can work well. The radio must be able to tune in small steps (10 Hz), or have some sort of a fine tune adjustment.
A good antenna is a must. It should be located away from the computer, to minimize any pickup of radio interference. Good quality coax cable should be used to connect the antenna to the radio. Proper grounding will also help reduce interference and improve reception. An outside antenna (dipole or active antenna) is recommended.
Connecting the radio to the computer can be as easy as getting an audio cable (from say Radio Shack) with the proper connectors on each end. Often you can just plug a cable from the speaker or headphone jack of the radio directly into the Mac's microphone jack (which uses a 3.5 mm plug). You need to carefully adjust the volume on the radio to not over-drive the Mac's sound input, you don't want to blow anything up.
In a pinch, you can use a Mac microphone, and set it on top of the radio's speaker. You'll need to watch for outside sounds that can get picked up, and create interference.
Tuning in fax stations on HF (Shortwave radio)
There is a great deal of confusion on how to tune in fax stations. This is partly caused by the non-standard ways that stations state which frequency they transmit on. Some give the carrier frequency. Some give the center frequency. All we care about is making sure that when the fax station sends a black pixel, we hear a 1500 Hz tone, and when it sends a white pixel, we hear 2300 Hz. That's it. When you keep that in mind, tuning in a fax station is extremely simple.
First, make sure MultiMode is set up correctly. You'll want to be in fax mode of course. Set the speed to 120 LPM (unless you know otherwise), and the mode to GREY and HF.
Next, tune in the station. You don't need to be precise yet, just make sure you can hear the fax audio. Make sure you've really tuned into the correct station, not a nearby station that may be sending RTTY or some other mode. Make sure you're not getting interference from other stations, and that the signal is fairly strong and clear. If it is noisy, your fax picture will be noisy as well.
When properly tuned in, the station should sound like this
Now, make sure the volume is appropriate. You want the volume indicator in MultiMode (the green bar in the upper right corner) to be around half-way, maybe more.
Finally you need to properly tune in the station. There is a small frequency graph display in the upper middle part of the MultiMode window. It shows what audio frequencies are present, typically this looks like a small bump or hill. There are two small ticks on the bottom of this, to indicate 1500 and 2300 Hz. You want to tune the radio until the bump is between the two ticks. Usually it is the same width, if the fax image being sent has shades all the way from black to white. If not, it may be slightly more narrow.
If you're decoding something, but it doesn't "look right", it's possible the station is using a mode other than 120 LPM.
At this point, you should be receiving something that looks like a proper image. Now fine tune the radio, in case some areas of white background look gray, or black lines look gray. If the audio tones are too high, the image will look too light. Likewise, if the audio tones are too low, the image will look dark. With practice, tuning will become natural. If your radio has digital readout with enough digits, you can note the frequency, so the next time you tune in the station, it is much easier. Just tune back to the same frequency, and you'll be all set.
If you're decoding a chart or other image that is only black and white, you can set MultiMode to LINE mode. In this setting, received pixels are converted to either pure black or white, with no gray. This sometimes produces better images.
If the picture looks correct, but is slanted, then the timing is probably slightly off. All computers run at slightly different speeds, this can cause this problem. It's easy to fix, just adjust the timing delta in MultiMode. This is typically a small number, 0 if everything is perfect, otherwise ranging from maybe -10 to 10. Decimals are allowed, such as -5.7 or similar.
