Re: Poor WFM and zero NFM Demodulation Audio

Got it working on all modes now. I think the problem was the SDR# sound card driver or dll not correctly/completely installed. Deleted and re-installed SDR#. That fixed the NFM issue but caused my PC earphone jack to be dead. So I went back to Windows 10 settings, deleted and re-installed that drive...

Re: rtl-sdr help coach wanted

I think your problem is not setting frequency correctly. Pay attention to the big frequency numbers in upper left of spectrum display. They are in Hz. In your first screenshot you are tuning to 1 GHz (1.000.047.000 Hz) and there are some signals showing peaks. In that band, near cellphone frequencie...

NFM audio in the 2M ham band is either quiet or sounds like a buzz saw. Maybe heard a slight bit of very distorted human voice once. No ...

Re: RTL-SDR Device Not Found by SDR# or HDSDR (Intermittent)

Problem solved, I think. I noticed that when it wasn't found by the programs, the temperature of the dongle was much lower than normal. I had either a printer or a couple joysticks also connected at the time. Disconnecting those, the SDR works now and the temperture is back to normally hot.

RTL-SDR Device Not Found by SDR# or HDSDR (Intermittent)

New RTL-SDR V3 USB device intermittently cannot be found by apps. Windows 10. Re-installed drivers. Installation looks good, same indications as on the RTL website. But neither SDR# or HDSDR program finds the SDR. Disconnected dongle, reconnected, no luck. When it did connect today, I was able to he...
