Audio output on Circuit board to solve latency?

Is there a point on the RSP1 circuit board to sample analog audio? If there was a way to directly grab audio before it get converted to digital and sent to the USB port, that would solve the latency issues.

Re: SDRuno 1.22 Released

Thanks. I'm having a lot of fun with it. I keep learning new things as I go. Still using the RSP1, so I hope you keep supporting her. I do wish SDRUno was a bit lighter on memory. I have 6 GB and it doesn't seem to be enough to use the higher bandwidths.

Re: SDR Project

Use it to test different antenna and feedline configurations for satellite reception.

Re: IF GAIN

You can move the position and width of the notch in the EX control window of SDRUno. I set mine to go on either side of my receive bandwidth filters.

Re: SDRUno instability

That sounds like a loose USB connection or bad cable, but you're saying it happens on two different systems?

Re: IF GAIN

One disadvantage is that your gain will not vary to match the signal on your precise listening frequency. You could solve this problem by using a notch filter and notching out the nearby offender.

Re: Erratic RF Gain control

I think you are going to figure it out after you play with it for a while. Maybe you have figured it out already. There are several variables that influence the RF gain control and the AGCs (yes, there is more than one). Look for them and experiment. One major factor is the level of RF noise at the ...

Yes, I've been seriously considering building a filtered and regulated power supply.
