My GS ID 724 was working well, then suddenly while I was a way, It went really bad, Lots of noise in the waterfall. This was caused by the Fake fleebay rtl-sdr v3 which I replaced with an el-cheapo $11 version which was working before. In fairness, I got a full refund…eventually.
Be aware there are many fake rtl-sdr dongles out there. Most of them. If you know where I can buy a guaranteed genuine V3 rtl-sdr please let me know. Unfortunately buying a Chinese product via the US makes it very expensive because of the ridiculous US and Australian postal charges.
