Nooelec RTL-SDR v5 SDR - NESDR Smart HF/VHF/UHF (100kHz-1.75GHz) Software Defined Radio. Premium RTLSDR w/ 0.5PPM TCXO, SMA Input & Aluminum Enclosure. RTL2832U & R820T2 (R860)-Based Radio

Ive been using UniTrunker software with a cheaper receiver that had the RTL2832U & R820T Tuner. It worked, but drift corrections were massive, the receiver was easily overloaded, and sensitivity/selectivity was not up to par. This little NooElec receiver basically fixes all of those issues for just a few dollars more. Since it uses the same receiver and tuner, it was a simple drop in replacement of my other receiver. It took off and began working immediately. I track a VHF trunked P25 system that has simulcast issues from time to time. It can really whack the receivers while trying to listen to distant towers. I wont say this NooElec receiver is completely immune to the RF onslaught but it is heads and tails above slightly cheaper versions. I also attempted to listen to an adjoining state 800 P25 system. My old receiver would BARELY register a control channel while the NooElec, using same antenna and gain settings, is easily able to hold the tower and provide reliable decode over 60ish air miles. It also comes with a real connector!!!! Those infuriating MCX connectors so commonly seen are completely negated by the NooElec and its SMA connector. Overall, if your software requires a receiver with the RTL2832U & R820T Tuner, it is hard to beat the NooElec with radios even twice as expensive. Very happy with the upgrade.

TCXO is great, no issues with P25.

Great quality SDR. Much better than the cheap Chinese models that are out there, but not so terribly expensive as the top-end SDRs. Very definitely well worth the price.

I couldnt wait to try this. Bought the hookup cable for my usbc port, the antenna, and downloaded SDR driver, and RF analyzer. Got nothing but noise. And Im in a great radio area. Not even FM. Before giving up, I tried it on my windows 11 computer. But absolutely nothing.

I have both the NESDR Smart v4 and the NESDR Smartee v2 (the same but with bias tee built-in) and they both offer equal performance that is notably better than generic RTL SDR dongles from China. The 0.5 PPM accuracy of the temperature-compensated crystal oscillator (TCXO) is great (meaning that it tunes the exact actual frequency you select digitally and stays there) plus the noise level is 2-3dB lower than no-name products. Just as important, the number and strength of interfering signals in the form of images, spurs, and birdies across the bands is substantially lower in these Nooelec products. Well worth the extra few dollars.

Have it connected to my 160M Dipole antenna, 264 Ft long and has NO Receive qualities what so ever! Using with Airspy and HDR Sharp. Great programs that I used with the cheap NooElectric dongle that I broke. Thought Id pay a lil more and get this but VERY disappointed! Dont waste your $$$$

it does everything I need it to. frees up a two way radio that I typically use to monitor freqs. The high the freq you listen tot he hotter it gets. small CPU fan works well to solve that. not a complaint just a fact of life with electronics.

I very much like this particular SDR. It is reliable, picks up quite a bit and has plenty of settings to adjust for the perfect signal reception. That being said I also purchased their e4000 based model and actually like it more for what I commonly do

This worked right out of the box on my Windows 10 laptop. I followed the provided instructions for installing the driver, then installed the rtl_sdr package and tested. Im using it in the 915 mhz band to get data from my utility/electric meter and other small/local sensors. The nice aluminum housing dissipates the heat well. It only gets mildly warm when used continuously at 915 mhz. As others have noted, the typical laptop and computer monitor make a lot of radio noise. Its important to use a USB extension cable to get the radio and antenna at least a few feet away from the laptop and monitor. When too close, its hard to find a signal within all the noise. I tested with rtl_sdr, sdr# (also called sdrsharp), rtlamr, and rtl433 -- all on a Windows 10 laptop. Everything worked well.

Ordered 2 of these for a P25 phase1&2 scanner projects using this with a Raspberry pi 4 and a free program called OP25. My local Leos went digital and we couldnt see spending $400+ for a scanner so we did our research and built our own for less then $200 each
