Review: Great little SDR, well worth the price - Very impressed with the ability of this device. I preloaded SDR# while waiting for next day delivery and once the RTL-SDR arrived I ran the batch file to copy the correct driver and then ran Zadig to install the driver. I put one of my HT antennas on the SDR and ran the SDR# software. Once configured it found the RTL-SDR device, but no signal, nothing wrong, just had to turn up the RF gain and viola. Thus far I have successfully tested broadcast FM, NOAA weather channel, and the 70cm Ham band. A disclaimer, I am an electronics hobbyist, licensed HAM, and a software developer, so YMMV...
Review: Nice upgrade from ver 3 - Working great so far although its not exactly "plug and play" (which I expected) .. I'm using a Pi3 with the PI-SDR image. Works great with SDR++ on the image. The one issue I'm having is not being able to pickup AM broadcast bands. I suspect thats antenna related but not sure yet. This has been fun to play around with. Not allot going in my area with uv- vf so cant comment on that yet. I have a MLA-30+ antenna coming soon. Will update here more after that. I can say its definitely an improvement over ver 3 just because of the increased coverage. Looking forward to installing on a android tablet . Update - works great. Overall .. these are cludgy to use compared to a dedicated radio, but fun and allow you to learn and experiment with several spectrums of RF. I was finally able to get AM but ended up installing and using on a Win11 machine. You will probably want to set up multiple antennas to use with one of these. The MLA 30+ works great on HF and lower bands but truly doesnt perform well at all above 30 MHz (expected). For that I'm going to try a simple setup with a DPDT switch and use a long wire (by long I mean about 15 feet strung along the floor). The ability to go lower in the bands makes this a worthwhile purchase. I never went the route of the upconverter before because of the added cost and hassle . Plenty to experiment with and learn. Now that I feel like I have the antenna situation addressed and have a baseline I can start tweaking the software and bookmarking stations. Nice to have good sounding stereo FM radio available on my PC setup as well. I still have a couple things I want to try - like going portable in the camper, completing a comparison of SD# and SD++, things like that. This thing will keep me busy for a while.

### ⭐⭐⭐⭐⭐ Nice upgrade from ver 3

### ⭐⭐⭐⭐⭐ Good Performer For L Band Weather Satellites
*by K***A on November 27, 2025*

This device is used to receive NOAA GOES-19 HRIT enviromental data at 1694.1 MHz. For the price, this is a very decent SDR, well regarded by enthusiasts. However, top end is 1.766 GHz and the V4 is running out of sensitivity at that point. The system here for receiving geosynchronous weather satellites is a 30" prime focus dish with the Nooelec feed system, about 20' of RG-8x cable to the SDR. Using Satdump software the average SNR is ~6.5 dB. This base system uses the SDRPlay RSP1a - at about 3X the cost of the RTL V4. The RTL-SDR produces an average SNR of 4.2. This is fine, as Satdump decodes reliably with 1 dB of headroom. No problem! For the price, the RTL-SDR is hard to beat. I have multiple SDR in the shack and this one is usually the choice for general work. There is a lot of junk out there in the SDR world...for general SWL use I highly recommend this unit. But, do your homework first...know your application. Regarding GOES-19 (EAST), my station sees it at 40 degrees of elevation from 72 degrees W.
