Housed in a durable silver brushed aluminum enclosure, it supports multiple devices simultaneously without USB interference. Proudly designed and built by Nooelec in the USA and Canada, it comes with a 2-year warranty, making it the go-to choice for professionals and enthusiasts demanding top-tier RF performance. ## Description This premium RTL-SDR was designed, developed and fabricated by Nooelec in the USA and Canada in order to implement a wide array of feature requests. The integrated, highly-regulated 4.5V 250mA bias-tee is ready to power your RF accessories--no hardware or software modifications are required to activate the bias-tee. The bias-tee is protected by an automatically resetting fuse, to ensure your investment is safe from accidental short-circuits of the RF input.Compared to R820T-based devices, this E4000-based SDR excels at sensitivity at 1500MHz, and is capable of far higher frequencies--up to approximately 2300MHz. There is a small gap in frequency capability near 1100MHz. As such, we do NOT recommend this device for ADS-B usage. For ADS-B, consider NESDR SMArt, also available on desertcart.For full product specifications, please visit our website at nooelec.com Included: βœ” NESDR SMArTee XTR SDR in silver brushed aluminum enclosure SDR Specifications: βœ” RTL2832U Demodulator/USB interface IC βœ” E4000 tuner IC βœ” Integrated, always-on bias-tee (4.5V, 250mA max) βœ” 0.5PPM, ultra-low phase noise TCXO βœ” 2 RF-suitable voltage regulators βœ” Shielded primary inductor βœ” Integrated custom heatsinkβœ” 2 silicone pads βœ” Female SMA antenna input βœ” High-quality silver brushed aluminum enclosure βœ” Frequency capability approximately 65MHz-2300MHz, with small frequency gap near 1100MHzTCXO Specifications: βœ” Frequency stability: 0.5PPM (max) βœ” Phase noise @1kHz offset: -138dBc/Hz (or better) βœ” Phase noise @10kHz: -150dBc/Hz (or better) βœ” Phase noise @100kHz: -152dBc/Hz (or better) Review: Well worth buying in for demanding situations - This is a nice little SDR when paired with a LNA. I use it for Aero and Marine reception from Inmarsat in band L. Works great. Tough too, been outside in an enclosure for over a year. Review: Value for money and excellent quality - The NooElec NESDR SMArTee XTR SDR is a great bit of kit to use and is really good value for you money. Compared to a radio scanner you cannot have a better way of receiving radio signals for a cheaper price. The only drawback is portability. IE laptop, raspberry pi. There are some RTL SDR apps for android that will work with this hardware. Learn to use and setup your software correctly otherwise you may think you have a faulty device with no audio. Search Youtube for NooElec products and how to set up and use with RTL SDR software. Happy listening ! ## Features - Premium software defined radio NESDR SMArTee XTR in a beautiful silver brushed aluminum enclosure - A wide variety of improvements on other designs, including integrated 4.5V 250mA bias-tee, ultra-low phase noise 0.5PPM TCXO, 2 RF-suitable voltage regulators, custom heatsink, 2 silicone pads and SMA female connector - Designed from the ground up to reduce USB port occlusion. Run multiple NESDR SMArt series devices side-by-side with any USB-compliant device, including tightly-spaced embedded devices like the Raspberry Pi - SDR frequency capability approximately 65MHz-2300MHz. Frequency range can be extended down to 100kHz or lower with the Ham It Up, also available on desertcart (B009LQT3G6) - Proudly built by Nooelec in the USA and Canada!

Thank you! **Q: Is it safe to use this with a cheap chinese upconverter? could the bias-tee be damaged or the upconverter without a dc block?** A: The Nooelec designs use automatic resettable fuse. Due to the E4000 chip used this one also has a noise spike right where you tune - so one needs to offset tune, also a gap near the ADS-B frequency. As to up-converter, they add annoying noise and cheap ones even more: this device goes up to 2.3GHz - or did you mean at the lower end? If you want to receive from lower frequencies I'd suggest the Nooelec NESDR SMArt v4 SDR which starts at 25MHz and to go even lower look at the Airspy HF+ Discovery which starts at 500 Hz. **Q: Would i get SDR radio with this on my iphone 13, will it transmit to my iphone, or do i need a connecter ?** A: It is not iOS compatible. Thanks **Q: Can it recieve ham radio frequency’s?** A: The frequency range of this SDR is 55MHz - 2300MHz, with higher sensitivity under 500MHz and over 1500MHz. You can use this device to receive signals below 55MHz, but you would need to use an upconverter, like the Ham It Up, to convert these signals into a range that the SDR can pick up. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well worth buying in for demanding situations *by R***H on 2 October 2025* This is a nice little SDR when paired with a LNA.
