Re: SDR UNO + RSPduo + Decimation window

Hi SDRplay Support, I gave gone on holiday and am far from the receiver now. However the phenomenon happens when SDRuno is heavily overloaded and the Sys meter goes on the red part of the scale, sometimes the overload would get to the point where you have intermittent audio. This can happen if perha...

Re: SDRUno S-Meter Reading?

Sorry to contradict, but the S meter reading, in SDRplay devices, is tied to the system metered RF input in dBm, according to the universally known "S" rule. In fact, if you watch closely, the S meter indication DOES NOT vary with audio filter bandwith. It varies with input RF intensity, w...

Re: Time domain amplitude analysis?

Picotec manufactures PC scopes that also have a spectrum analyser function in their Picoscope software. For instance the PC scope model 2204A is quite unexpensive and will give you spectrum analysis to 10 MHz, with full recording facilities. You only have to feed your audio to the scope.

Re: RSP RECEIVER LOW NOISE HF OPERATION WITH LONG WIRE ANTENNAS

Please be aware that in the balanced n=6 filter schematic in the previous post all capacitance values were wrong. I have now replaced the wrong schematic with the correct version. Sincere apologies,
