Includes 1x QO-100 Bullseye TCXO LNB

This is a TCXO stabilized LNB for the QO-100 geostationary amateur satellite and other Ku-band satellites. Manufactured by Othernet. Standard LNBs used for QO-100 require modifications to be made to the circuit as the crystal needs to be replaced with a TCXO in order to avoid frequency drift. The Bullseye LNB comes with a highly stable TCXO which has less than 10 kHz offset even in outdoor conditions.

The Bullseye LNB is the world's most precise and stable DTH/consumer Ku-band down converter. Even a VSAT LNBF costing hundreds of dollars more is no match for the performance of the Bullseye 10K LNB. Each unit is calibrated at the factory to within 1 kHz of absolute precision against a GPS-locked spectrum analyzer. Under outdoor conditions, the stability of the LNB is well within 10 kHz of offset. As a bonus feature, the Bullseye 10K provides access to its internal 25 MHz TCXO through the secondary F-connector. This reference output can be used to directly monitor the performance of the TCXO over time.

NOTE: Requires a 12-19V bias tee power injector, the V3's 4.5V bias tee is NOT for this LNB. 11.5 - 14V enables vertical polarization and 16 - 19V enables horizontal polarization.

Discones are wideband antennas. This makes them ideal for the RTL-SDR as using a Discone will allow you to receive at almost any frequency with decent performance.

A 1090 MHz ADS-B antenna from FlightAware. Is weather proofed and has 5 dB of gain. Uses an N-type antenna connector. See our review post for more information.

Currently we recommend the SpyVerter as the upconverter of choice. Although it was designed to be used with the Airspy, it works perfectly with the RTL-SDR. It uses a 120 MHz oscillator, has excellent filtering and can be powered via USB cable or via the bias-tee on our RTL-SDR Blog dongles. The SpyVerter uses an innovative new architecture that reduces overloading, has better SNR than other options and can operate all the way down to DC.

With the above performance and features, the included metal case and adapters and at a similar or even lower price compared to other upconverters we think this one is the best value. See our review post for more information.

An alternative to the SpyVerter is the upconverter designed by SV1AFN.

It based on the ADE-1 mixer chip, uses a 200 MHz oscillator, has good filtering and works almost down to DC.

Another recommended option is the Ham-It-Up Upconverter.

This one like the SV1AFN is also based on the ADE-1 mixer, but uses 125 MHz oscillator and is based on an open source design. There is also a metal case available on Amazon and eBay. However, currently we would recommend the SpyVerter or SV1AFN over this option.

If you are monitoring ACARS or air traffic signals then you may want an air band bandpass filter if you find that you have lots of interference from nearby stations such as FM broadcasts and Pagers.

FlightAware sell a very affordable ADS-B band pass filter. Many users have reported significantly improved reception when they started using this filter. This is probably the best filter to get if you are interested in ADS-B. See our review post for more information.

We also highly recommend the ADS-B HABAmp for receiving ADS-B signals. This is a filter + LNA combination that works very well and will significantly improve ADS-B performance.

We've tested these ourselves with the activatable bias tee in our units and found them to definitely work very well.

This product is great for if you are using an upconverter together with your RTL-SDR, or other SDR. Contains seven band pass filters that range from 1.6 - 2.5 MHz, 2.5 - 4.7 MHz, 4.7 - 7.5 MHz, 7.5 - 14.5 MHz, 14.5 - 21.5 MHz, 21.5 - 33 MHz and 33 - 56 MHz.

The LNA4ALL is a very affordable wide band low noise amplifier that is very commonly used with the RTL-SDR. Has the ability to be powered externally from any voltage between 6V - 9V, or with a simple modification with 3V - 5V in bias tee mode.

We have tested the LNA4ALL in bias tee mode with the activatable bias tee in our units and found it to work well.

There are also several low noise amplifier circuits that can be found very cheaply for sale on eBay and most will do a good job. Unfortunately most don't provide a bias tee option like the LNA4ALL or HABamp does. Currently we recommend LNA's based on the SPF5189Z chip as they have wideband good performance, and are cheaply produced.

Ideally you want to get the RTL-SDR dongle as close to the antenna as possible. Normal USB cables have a length limit of about 5m before they stop working, but with an active USB cable this can be extended up to 10 to 15 meters.

We recommend these Monoprice cables as they have been reported to work successfully with the RTL-SDR dongle.

We recommend using RG6 coaxial cable for most links between your antenna and RTL-SDR. RG6 is low loss cable and it is also very cheap because it is used commercially with satellite TV installations.

RG6 is 75 Ohm cable. Note that the mismatch between 50 and 75 Ohm impedances is completely negligible for RX applications.

Noise and interference can sometimes be induced in the USB cable itself which can show up in the RF spectrum. To stop this noise use clip on ferrite cores on the USB cable. These cores help to suppress unwanted currents in the USB shield.

A Raspberry Pi is a credit card sized computer that runs Linux, or even Windows. With it you can connect an RTL-SDR, run a server, and then remotely send a signal or processed data such as ADS-B aircraft locations back via WiFi or Ethernet cable.

A USB on-the-go (OTG) cable is required to use the RTL-SDR on Android phones with software like SDR Touch and Wavesink. We recommend trying to find cables that come with power plugs so that you can use it with a power pack. Using an RTL-SDR can increase CPU usage which can quickly drain a mobiles battery.

If you are using a long wire or random wire antenna with a HF modded RTL-SDR or an upconverter you should use a 9:1 impedance transformer to get good SWR.

There are also several other alternatives available on eBay that use a larger iron core.

A wideband noise source can be used together with an RTL-SDR dongle to perform measurements on filters and to measure the SWR of an antenna.

See our tutorial here for more information.

Airspy SDRs have high performance RX capabilities with mid tier pricing. Their units really shine when used in tough RF environments, such as in RF environments with strong and weak signals together. The Airspy is an excellent upgrade from an RTL-SDR dongle. 

See our review post for a comprehensive comparison between the Airspy, SDRplay RSP and HackRF.

Another good mid range SDR is the SDRplay RSP line of receivers. These SDRs are great value for the price and can receive HF frequencies without an upconverter. Previous iterations were behind the Airspy in terms of overall performance, but the RSP1A and newer models are on par.

See our review post for a comprehensive comparison between the Airspy, SDRplay RSP1 and HackRF.

The HackRF One is a relatively low cost TX/RX capable SDR. It is designed for radio experimenters and it has a very wide band frequency range from 1 MHz to 6 GHz, and a wide bandwidth of up to 20 MHz and an 8-Bit ADC. It is probably the most versatile SDR that exists at the moment, but in a compromise it does not have the best quality RX or TX performance. Thus it is perfect for experiments like reverse engineering and testing RF devices, but it is not intended to be used as a commercial radio or ham radio.
