so ive been using a cheap RTL-SDR v3 dongle for about a year now mostly just scanning trunked systems locally and poking around HF with an upconverter i built. works fine honestly but ive been eyeing the SDRplay RSP1B because the coverage without needing the upconverter sounds appealing and the dynamic range is supposedly way better.

my question is whether the jump is actually worth it for casual use or if im just falling into the upgrade trap. i mostly run SDR# on windows and occasionally fire up GQRX on a raspberry pi when im feeling adventurous. not doing anything serious like decoding weak signal digital modes or serious spectrum analysis, mostly just listening and occasionally logging aircraft with dump1090.

anyone actually made this switch and noticed a real difference day to day or is the RTL-SDR v3 good enough for what im describing. i dont want to spend the money and then realize i cant tell the difference at my noise floor anyway

honest answer is for what you're describing the RTL-SDR is probably fine, but the RSP1B is a genuinely better piece of hardware and you will notice it on crowded HF bands. the 12-bit ADC versus 8-bit makes a real difference when there's a strong broadcast station nearby killing your dynamic range. had an AM broadcast station about 15 miles out that was basically washing out everything within a few MHz of it on the RTL, RSP handled it much better with the selectable MW notch filter.

that said if your main use is 1090 ADS-B and scanning VHF trunked stuff you probably wont notice much difference there. the RTL is already pretty good at those frequencies. id say if HF listening matters to you at all the SDRplay is worth it, the SDRuno software has gotten a lot better too even if it's a bit cluttered at first

i made that exact jump like two years ago and dont regret it but i'll be real the learning curve with SDRuno threw me off for a while. coming from SDR# it feels like someone designed the UI after staring at a rack of vintage test equipment. took me a weekend to figure out where everything was. once you get it dialed in though it's solid and the RSP1B handles MW and HF without any extra hardware which was the main thing for me. no more upconverter box sitting on the desk.
