Review on 📻 Nooelec NESDR Smart v4 SDR: Premium RTL-SDR with Aluminum Enclosure, 0.5PPM TCXO, SMA Input - Software Defined Radio Review by Derrick Milkie

So much bandwidth, all kinds of decoding, tuning and demodulation software for <$25? "Before" something that could do this would cost you thousands of dollars. What initially interested me was getting image data from NOAA satellites etc (I have yet to build a QRP antenna). What attracted me is anything else you can do with it. Update: I built several different antennas for it and got a plus for it. A lot of fun. I've added some NOAA satellite imagery that I recently received from NOAA 19, 18 and 15. I used a quadrafillar helix antenna I made from cooling tubes (strong signal, I don't even need a low noise amplifier. I bought a cheap one but doesn't matter). I use the HDDSDR program. I set 137.1MHz for NOAA 19, 137.9125MHz for NOAA 18 and 137.62MHz for NOAA 15. I've set the demod to FM and the bandwidth to 96000 (must make sure you get all of that or else it will be grainy if set tight too). I set the audio output to a virtual VB audio cable (that's the program Twitch and Facebook streamers use to send audio to other programs, in this case your picture decoder). My image decoder is WXtolmg. I set its audio input to a virtual VB audio cable and that's it (there are a few more things like setting up the satellites to look for, updating the keplers, splitting latitude and longitude so it knows when it should record automatically for a pass-on-satellite, etc.). I've deciphered some really good clear NOAA weather photos with it, I'm still surfing the web looking for other cool things to do with it. track planes? uh, maybe. Watching the hydrogen line with a parabolic antenna? (radio astronomy stuff) erm maybe but I need to buy a Saw filter, FM trap and VLNA for it. I'm trying to keep costs down but that's an option for later as I have a dish for it. If you have this equipment, you can also connect GOES satellites. I was trying to fix one with my crappy low noise amp and cymbals, no dice. You need a good LNA and saw filter for this. The most interesting thing I get from this thing is the low frequencies with my Ham it up plus, 40m band decoding really weird Morse code conversations. then play the VLF tapes recording atomic clock signals (60kHz from Fort Collins) and who knows what else.
