so ive been using an RTL-SDR v3 for about a year now mostly just scanning aircraft and some 2m/70cm stuff, works fine for what it is. but ive been wanting to get into HF listening more seriously and the direct sampling mode on the v3 is... okay i guess, definitely usable but it feels a bit deaf compared to what people describe with proper SDR receivers.

been looking at the SDRplay RSP1C, its sitting around $130 which isnt crazy money but its also not nothing. the spec sheet looks impressive, 1kHz to 2GHz coverage, 14-bit ADC vs the 8-bit on the rtl dongles, but i genuinely cant tell how much of that matters in practice for someone just doing casual HF monitoring and maybe some 40m/80m band listening in the evenings.

anyone actually made this jump and noticed a real world difference? not looking for lab measurements just like... does it actually feel noticeably better when youre sitting there tuning around 7MHz at night. also curious whether SDRuno is as annoying to set up as people seem to think or if thats overblown

made exactly this jump about two years ago and yeah the difference on HF is pretty substantial, not subtle at all. the direct sampling hack on the v3 is clever but the noise floor is just noticeably higher and weak signals that are readable on the RSP1C kind of wash out in the mud on the rtl. 14 bit dynamic range matters a lot more than i expected, especially if you're anywhere near a strong local broadcaster because the rtl will get absolutely hammered by intermod.

SDRuno took me maybe an hour to figure out but once its set up i dont really touch it. the workspace thing is a bit different from SDR# but its not bad. only gripe is it does feel a bit heavy on CPU compared to SDR# with the same dongle. if you do go RSP route i'd honestly suggest also trying it with HDSDR or even SDR# with the mirics plugin some people prefer that over SDRuno for everyday use.

the RSP1C is solid but just wanted to throw in — if you think theres any chance you'll want to transmit eventually or get into more advanced stuff, a HackRF might be worth considering instead. yeah its more expensive and the receive performance isnt quite as clean as the SDRplay for straight listening, but having TX capability opens up a ton of stuff. i use mine for everything from playing with WSPR beacons to testing antenna patterns. just depends what direction you see yourself going i guess.
