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....

Re: RSP-1 and SDRUno 1.23 and newer?

OK, first bit of feedback... WHY don't you have code that adapts the saved settings and workspaces of one version to the next? Even if things in this or that particular window end up off a bit, I sure as heck don't relish the idea of setting everything, and I mean EVERYTHING, up again. Have you cons...

Re: RSP-1 and SDRUno 1.23 and newer?

OK, then, thank you for the support. As I mentioned, one of the selling features of software-defined radio is that the software can (and by implication WILL) improve for the same hardware. I do understand the need to sell the latest hardware, and I will most certainly buy the latest again at some po...

Re: SDRuno NB settings?

I've found the SDRUno Noise Blanker can work - sometimes quite well indeed... For example, we have a washing machine with a motor controller that really lights up the airwaves with RFI that's so nasty sounding I just can't stand to listen to anything when it's on, and it crosses the shortwave band! ...
