Re: Newbie : listening 3Khz to 148 Khz with upconverter ?

24 bit sound card has dynamic range up to 140 dB... well not all, but let's say we have 130 dB dynamic range. With 1V line-in input, the receiver sensitivity will be about 0.3 uV. This is more than enough for VLF band. Because background noise is much higher than receiver sensitivity through 1V line...

Re: ExtIO_RTLSDR# - custom ExtIO for RTLSDR

I saw that you wrote that if needed you could compile one (6bit ExtIO_RTLSDR#). Could you please? :D yes, I can compile it for x64. But I'm not sure that I can test it on this software, it needs time to research what is it and how it works. I can share it here, but I think first version may works i...

Re: distorted FM

try to place your antenna at half wavelength distance from Ground, any kind of building, metal roof or wires. Also add RF choke on the feeder, near antenna feeding point. And it will works fine.

ExtIO_HPSDR# - ExtIO for HPSDR devices (Hermes / Hermes Lite, etc)

So, I decided to share it here. This ExtIO plugin allows to use HDSDR with DDC SDR receivers and transceivers supporting H...

Re: SDRUNO version EXTIO

the only version which supports EXTIO is v1.22 EXTIO version, you're needs to start SDRuno.EXTIO.exe.

If you start SDRuno.exe, it doesn't supports EXTIO and works with SDRPlay device only
