I think Wes is using RSP Duo Joanne but same may apply with RF gain set so high? Although Wes says he has tried many different gain settings. Like you, need to see the screengrabs to go any further as I don't feel we are seeing the full story?jdow wrote: ↑Sat Dec 23, 2023 9:31 am PS: Back of the napkin analysis.
8 bits sampling is about 50 dB of dynamic range for the raw sampling.
At 2.4 Mbps (the one true usable sample rate) and a 100 Hz RX bandwidth you get another roughly 44 dB, So there is a total 94 dB of dynamic range. So it is very likely that being able to receive a weak signal in a system with perhaps an effective 30 dB noise figure, depending on operating frequency, means reception down to about 124 dBm and an overload signal well above -34 dBm has hte rtl dongle overloaded badly on transmit. It has quit sending useful or accurate data to properly trigger mute on a 1W signal with 60 dB isolation, -30 dBm.
Wes already posted some screenshots before back in February:

First thing I noticed was running very old SDRC v3.1, but he since says he has updated to 3.3 Beta and same thing. Odd.
Actually Wes I wonder if a complete uninstall and fresh reinstall of 3.3 Beta might do the trick.
