sdr play features?

I've been tinkering with sdrplay with e4000 dongle. I think I've got it all installed properly. I've also played with SDRSHARP and HDSDR. SDRPLAY seems to be missing an obvious key feature. On HDSDR I can click drag the spectrum to any band of frequencies I want. I can't make that kind of function h...

Re: distorted FM

by click dragging the edge of the envelope so the bandwidth is expanded. My experience is that with most FM the distortion is due to using too narrow a filter, the FM modulation goes outside the filter. Another option, try installing sdruno. Its free too.

Re: distorted FM

Have you tried adjusting the bandwidth of the filter? It looks like there is some clipping of content between the main signal and those 2 digital sidebands?

Have you observed the same problem on other FM stations?

Re: SDRUNO version EXTIO

Sorry for my bad, I forgot how to properly run sdrplay with usb dongle. It requires that I execute SDRuno.EXTIO.exe instead of just SDRUno. Then it works fine.

sdrplay fails -no available rsps

I had been running sdrplay with the old rtl2832 dongle. On a W7 32bit lenovo laptop. The extio2832.dll is in the my documents folder. However, last week when I launch it fails with “no available rsps available”. This same dongle will work with sdrsharp and hdsdr on the same laptop so something has c...

Re: SDR has clear strong signal, 2 Meter ham rig has bad signal using same antenna

Besides possible antenna connection problems something could have blown out the front end receive transistor/fet of your handy talky. I would think even the lowly uv5r would have a better receiver than a dongle.

sdr uno hdsdr how are filters set?

I think sdruno works with hdsdr, right? If so I'm wondering how the programming of all those bandpass filters is managed? Is the desired frequency information sent via usb up to the rsp1 unit that then selects the proper bandpass?

best place to ask sdrplay questions

Can anyone recommend a good forum to discuss sdrplay installation software? I know that the sdrplay official site is shutdown and I am not getting any responses here. My question at the moment is related to getting sdrplay to run under w10. I have it running on w10. I had to put the extio.dll in the...

Re: SDR # Set samplerate error

Its all personal preference, but I like the HDSDR. Just need to get that extio.dll in the right place and launch as admin.

Re: odd dark spot on audio decode with hdsdr

OK, this is , op error. I had turned on the auto-notch filter. I need to figure out how that works.
