### ⭐⭐⭐⭐⭐ Nice bit of kit

### ⭐⭐⭐⭐⭐ Good price vs quality
*by P***S on 3 October 2025*

Work very well for the price.

### ⭐⭐⭐⭐⭐ Much better on the HF bands than the V3
*by S***E on 18 June 2024*

I purchased the RTL-SDR V4 to upgrade from the V3 which I've had for over a year. I usually listen to the HF amateur bands and the V4 seems to be much better in this regard - less noise and interference and better sensitivity. I don't have a great setup - just a long-wire antenna about 13 meters long in the back garden but have heard contacts from all over the world. The unit does get very warm in use and, even though they say this is normal, so as not to shorten it's life I have attached an extra heatsink so that it now runs much cooler. I have tested it on the air bands, marine bands and commercial bands and all work just fine with clear reception. If you already have a V3 for listening to HF and are thinking of upgrading I'd suggest this is a good purchase especially for the price. There is less benefit to UHF, VHF etc so if this is your usual listening range the V3 is probably already more than adequate.
