Re: SNR meter, bandwidth and gain adjustment for transverters


Conrad, PA5Y
 

Hello Max, not quite at least I don’t think so. Does this affect the metering? But thanks, I will have a play around when I have time later. I was thinking of something that allows calibration to a known input level. So I put -30dBm in and can read that directly on the meter as -30dBm.

 

Regards

Finally, as a feature request would it be possible to have some manual gain adjustment to compensate for transverters and LNAs?

Hi Conrad

I am no expert..... in fact very far from it, but have you seen the Visual Gain setting? It's available on all the rigs I use with SDRC (HL2, RSP2Pro, RTL-SDR V3). Not sure if Simon has implemented it for every radio that can be used with SDRC as it's in different place depending on the radio? Here it is for HL2 and RSP2Pro:

   

Can calibrate for zero signal (i.e.antenna disconnected). Is the feature you are alluding to?
