10m+11m Bands Activity 5 SEP 2023 (RTL-SDR V4)
« on: September 05, 2023, 2022 UTC »
Doing a quick upper HF test of the recently released RTL-SDR V4. Using my 31' vertical antenna as usual. 3.2M/s sampling rate, so a waterfall showing ~26-29MHz.

There is some RF imaging or similar right at the 28.8MHz lowpass filter, but that is largely a "whatever" IMO.

The V4 is not really a SDR for serious weak signal HF work, but it has thus far sufficed fine for casual listening. I am not using any extra external filters at this time, either. It is certainly a better situation IMHO than dealing with a V3 for casual HF listening using an upconverter and often needing external filters.

Lowered the sampling rate to ~900K/s and narrowed the RFBW for those perhaps interested.
