For reference a fully 1 GIB Ethernet link might make it to about 25 Msps if there was absolutely no other traffic on the link. If it goes wireless anywhere 8 Msps could very well be right up at the li

Tricky drive level setting for SDR Console to Pluto, QO100
I suspect that if you check it out Simon's 2.8 kHz filter is narrower than a conventional crystal filter's 2.7 kHz even at 30 dB down. {^_^}

Sigi = SDRSharp does this, too. SDRC is what happens when SDRSharp grows up and sheds it the GUI library it's using. {^_-}

When bands overlap it would be nice to be able to create horizontal color bands with the primary class on top working down to ISM uses on the bottom. (Warning - snob snarky statement) Any ham who need

Reinstalling SDR#
#sdrsharp
Your first mistake was deleting HDSDR. It has nothing to do with SDRSharp. The second mistake was deleting SDRSharp. You do not have to. You can have several SDRSharp's installed, each in its own fold

Voltage variable attenuators also have IMD. Are you measuring right at the output of the attenuator or is there a buffer on chip? It will also affect the cross coupling within the chip between the out

I'll believe that. But it was possible that the USB 3 port controller was in some data contention issues. RX888 going full speed would prove that. That's why I asked. {^_^}

That REALLY REALLY sounds like a firewall issue. Is your wireless network behind a NAT firewall of its own? (That is a nice secure way to handle it.) {^_^}

Mumble mumble.... USB 3,0 was supposed to be about 500 MBps (BYTE/s). So it should support, just barely, a sample rate of 125 Msps for 16 bit I/Q samples. Is that 24 MHz a limit only for B200 or for R
