Re: Bandwidth of the s-meter in CW-U mode
The SDR console s-meter IS accurate. I am lucky to own a good signal generator with a calibrated power output and I tried feeding a signal from-80 to -120 dBm to my RTL SDR and got a very linear response from the SDR console s-meter readings. The difference between th s-meter reading and the known p...

Measuring noise figure of a preamp with SDR Console
Dear Simon, First of all, thanks for witing this superb software. Over these last few days, I finally succeded measuring the noise figure of some VHF preamps I have here. The results seem quite accurate and maybe some users of SDR Console could also be interested in measuring their own preamplifiers...

Bandwidth of the s-meter in CW-U mode
Hi all, I am measuring the noise factor of some antenna preamplifiers by sending a calibrated signal into the preamp followed by my RTL SDR and SDR console. I am using the so-called "gain method". To use this method, I must measure the gain of the system (preamp + receiver). This is easy t...
