Re: Feature Request: Customizable Audio Bandwidth Preset

Oh, and yes, I know I can move the bandwidth to just the right place with the red lines in the AUX SP window. This is just a request for a bit more convenience.

Feature Request: Customizable Audio Bandwidth Preset

I find when SWL listening to AM stations, sometimes packed in like sardines, I would like just slightly less than 5000 Hz bandwidth on either side of the carrier - for obvious reasons. Rejecting the high pitched whine of an adjacent carrier would be preferable. The closest preset on the RX CONTROL w...

Re: RSP-1 and SDRUno 1.23 and newer?

Thanks. Once I got it installed and and set up, and if I don't tune it around too much, it seems like maybe 1.23 is delivering slightly better audio than 1.22 on the same stations. Could it be that the phantom signals are just different because of the different internal choices for sampling rates, I...

Re: SDRuno V1.22/V1.23 an observation

Paul,

I've found for my RSP-1 that the LNA control is inverted. See if that might be the issue for you as well with your RSP2.

Re: RSP-1 and SDRUno 1.23 and newer?

May I suggest making the SDRPlayAPIService service demand start and have the SDRuno software request it to start and stop. I don't want an extra service running when I'm not using the radio, so I've coded this workaround batch script. I start it Minimized and set the folder to the SDRuno installatio...

Re: bugs in sdruno

I can hear a change in the cutoff frequency, but I presume that's normal. You'd expect to hear higher pitches of hiss as the cutoff frequency goes farther from the base. I experimented with putting a notch filter at various points and with various widths, and I still can see no way that could affect...

Re: bugs in sdruno

Try as I might, I cannot sense what you folks are talking about with the "ringing sound"...

Can you please be more specific about what settings you're choosing?

If I'm missing out on a way to improve the audio I should love to learn about it.

Thanks.

Re: RSP-1 and SDRUno 1.23 and newer?

Audio quality is poorer with LOW IF at startup with 1.23 than with 1.22. I tuned 10.0 MHz at startup and it sounds like there's a very low (a few cycles per second) beat frequency against WWV when I start 1.23. That's not there with 1.22.

Re: RSP-1 and SDRUno 1.23 and newer?

The LNA button is backwards, which may be at least partially responsible for the above. The display cleans up some with the [ LNA ] button lit up. Note that the IF GAIN / IF ATTEN slider is practically unresponsive if one disables the [ AGC ] button. I *might* be able to live with this for a while b...

Re: RSP-1 and SDRUno 1.23 and newer?

Second bit of feedback: SDRuno 1.23 is useless with an RSP-1 for shortwave listening. Set up the same in every way I could see, with 1.23 I find MW stations are hammering the entire shortwave band. Yes, I know there's no dedicated special MW filter in an RSP-1. However, SOMETHING is seriously wrong....
