Nooelec NESDR Smart v4 Bundle - Premium RTL-SDR w/Aluminum Enclosure, 0.5PPM TCXO, SMA Input & 3 Antennas. RTL2832U & R820T2-Based Software Defined Radio.

Scanners and 2 way radios are much more expensive than I imagined. I've owned them for more than 20 years. As so many departments in my region have migrated over to P25 digital communications, the price of multiple scanners has just become out of reach for me! I know precisely how much I have to spend, but what do you think? NESDR is here from NooElec! SDR Console w/DSD+ and the antennas it comes with made it so easy to hook up to a tablet to listen to police and fire. I can listen to six frequencies simultaneously on this little sdr compared to my $400 and $500 The device does get warm at times, but the frequency doesn't drift, the sound is decent, reception is excellent in my area, and it does everything I ask. This device is a great value, too. This product has really caught my attention and I plan to buy at least two more to play.

A dream come true for engineers. Having these available for RTL-compatibility is a big plus You can use SDRs. Moreover, they provide you with a set of 3 There is also an email link via NooElec that instructs you on how to setup the Windows version of this SDR. I really appreciate the price on these as you can play around with them if you want to look at the RF spectrum or check signal levels for your new scanner antenna! A (SMA male to F female adapter) is also helpful for hooking up an outdoor antenna setup for better signal strength and less interference (noise floor) from your computer, etc. It is also fascinating to see how big the signal is compared to the noise floor level. Getting that kind of accuracy would cost you thousands of dollars if you bought a high end device, but the SDR (with the free software) will keep you within striking distance. The only drift I encounter is after an hour or so, when I have at least one running all the time! A P- has been assigned to me There are 25 control channels, but the carrier peaks exactly at the same frequency since the whole day is spent at that frequency. There is no drift in it. There are no better specs to ask for. About the CB band (27Mhz) to about 1GHz is the range that it receives radio signals from. The 7Ghz band. This is great for "pirate experiments" of the radio type, as well. The software lets you listen to or examine any signal, however the chip will only decode audio on Analog signals if you point it at that. The P-type of digital photography 25 and similar signals will only be heard as brief bursts of noise. The digital signals P- have the following characteristics If you want to test two of these SDR units and other software, you will need to use advanced computer skills as well. Also, you can use it to look at FM radio broadcast data, as well as RDS data. As well as those, you can hear them. Additionally I own the NESDR mini 2, but I find this package deal to be better value. In spite of the fact that the case gets warm, it does not block other USB ports, so the designers did a good job. A toy cannot be compared to this. RF Analyzer Tool NooElec is the best radio receiver with a low price and delivers all the goods as a full-fledged advanced RF Analyzer with its reasonable price. They don't realize what a fantastic device it This particular device is something that I have longed to own for nearly You've got a great product here,.

(Originally, I wrote this review for the standalone dongle without the antennas. Due to the fact that it applies to this package, I am remaking it I'm posting it here for your information as well).

So far, I have been having a blast playing with this and have combined it with NooElec's "Ham It Up convertor to receive signals of under Software such as SDR Sharp does an excellent job for me. In all honesty, the three antennas you get are mostly useless, unless you're on top of a mountain without any other electrical devices nearby. In a modern household, there is a LOT of noise from electrical appliances. Almost every appliance can be plugged into a computer Whatever the size, you can count on us It's even possible for LED lights to emit their own buzz as well. Good quality coaxial cable needs to be fed to an external antenna in your attic, or out in the open. This old RG was finding its way back to me I have had excellent results with coax 6 TV. Using the "Ham It Up" converter will enable reception of signals in the lower 25 MHz range, but long wire antennas or tuned dipoles out of phone lines and out of the way of any other house noise sources are ideal. It will take a 9 to do that A balun (or unun) to link the antenna to your receiving system See if you can find it After purchasing one online, it didn't work at all (probably faulty),.
