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

The device worked very well for 2 months, and outperformed my previous SDR, however after 2 months of use, it no longer receives ANYTHING. The receiver has gone completely deaf. Ive tried it in 2 different PCs with the same result. It appears that something in the hardware has failed. Ive tried multiple antennas, and settings, but it hears nothing at all.....just static.

This RTL is alot better than the first evolution. It does get slightly warm during hours of use but does not drift in the least.

Using 5 of these to broadcast p25 phase 2 traffic using OP25. Works like a charm.

Performs perfect for running DSD-Trunk listening to Motorola trunked radio.

This kind of bandwidth, all kinds of decoding, tuning, and demodulating software out there, for <$25? Back in the day something that could do this would run you thousands of dollars. What interested me initially was receiving image data from NOAA satellites etc. ( I still need to build the QRP antenna). What sold me on it was everything else you can do with it. Update: Ive built a few different antennas for this and got a ham it up plus for it. Tons of fun. I added some NOAA satellite images I aquired from NOAA 19, 18, and 15 recently. I was using a Quadrafillar Helix antenna I made from refrigeration tubing (Booming signal, I dont even need a low noise amplifier. I bought a cheep one but it make no difference). Im using the HDSDR program. I set to 137.1 MHz for NOAA 19, 137.9125 MHz for NOAA 18, and 137.62 MHz for NOAA 15. I set my demodulation to FM mode and my Bandwidth is set at 96000 (have to make sure you get the whole thing or it turns out grainy if set too narrow). I set my sound output to VB virtual audio cable (its a program that twitch and Facebook streamers use to pipe audio out to other programs, in this case to your image decoder) My image decoder is WXtolmg. I set its sound input to the VB virtual audio cable and presto (Theres a few more things like setting up what satellites you want it to hunt for, updating keplers, telling it what your lattitude and longitude are so it knows when to auto record for a satellite pass and stuff). Ive decoded some really nice clear NOAA weather photos with this, Im still surfing the web to find some other cool stuff I can do with it. Track airplanes? eeeh, maybe. Observing the hydrogen line with my dish antenna? (Radio astronomy stuff) ehhh, maybe but I need to buy a Saw filter, FM trap, and a VLNA for it.... Im trying to keep the cost down but its an option for later since I have the dish for it. If you have that equipment, you can also pick up GOES satellites. I tried to lock on to one with my crappy LNA and dish, no dice... you need the good LNA and saw filter for that. The most fun Ive been having with this thing is the lower frequencies using my Ham it up plus, 40 meter band, decoding really odd conversations in Morse code. then play around in the VLF bands picking up atomic clock signals (60khz from Fort Collins) and who knows what else...

When received, one of the two units i orered was inoperable. I opened it up and found L4; part of the input power filter to the RTL2838 , missing. One solder pad showed signs of minor solder with the outine of where L4 may have been, the opposite end showed no sign of solder. I took the inductor off an old dvb rtl dongle i had and repaired the unit. Once working i couldnt be more pleased. Much better stability and sensitivity than my old dvb dongle. The units both are perfectly on frequency with no correction factor needed. After running for 8 straight hours, still perfectly on frequency. Solidly built and the sma connector aids in solid connectivity.

Really cool radio. Works well with most SDR Software. Get it!

as described, neat little receiver has many applications

Great Product when added to a mag loop litening antenna & Ham it up, up converter I can listen to broadcast stations, shortwave, Ham Frequencies, & even ULF long wave stations.

Works great for my purposes. I am using it as a panadapter connected to an IF tap in my HF transceiver. Great bit of technology. The SMA connector is way better than the tiny MCX connectors on some of the other RTL-SDR dongles out there, particularly if you are experimenting with different setups and need to disconnect and reconnect the antenna a lot. The aluminum case is nice as well. The TCXO appears to be very stable. The radio does not appear to drift from startup.
