Signal Strength Displayed by SDR#

[wxgeek99]

I like to send out some signal reports when hear a long distance station. However SDR# does not have a conventional S-meter. The scale goes from 0dB to -120dB. Not sure how to translate that into an S-meter type reading. Any ideas/suggestions?

From the Wiki on S Meter. Might be helpful.

I don't think that you can relate the Y-scale reading in SDR# to an S-meter reading. I suspect that the scale is dB relative to full scale on the ADC. As mbott suggests, an S-meter measures signal strength at the receiver input

There is a SDR# plug-in on the LevelMeter Plugin site which may help. Also HDSDR software has an S-Meter built-in. HDSDR can be downloaded at HDSDR Homepage.

From my experience with it, it does not provide an accurate S-meter reading. I have it installed, but I do not use it.

Still didn't manage to check it against real s-meter, but it doesn't look that bad

Accurate signal level measurement using SDR

SDRuno together with the SDRplay RSP1A, RSP2 or RSP2pro provides accurate signal strength measurement as demonstrated here (an RSP2 example): https://www.rs-online.com/designspark/highly-versatile-rf-power-measurement-using-the-sdrplay-rsp2

You can even use SDRuno as a datalogger for monitoring or charting purposes whereby you can write the measurements to a .csv file https://www.rs-online.com/designspa...ogging-accurate-rf-power-and-snr-measurements
