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

Post by waterman46 » Sat Oct 17, 2020 5:51 am

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 hear many FM broadcast stations and some 2M repeaters (144+ MHz).

Could be a USB problem.
Try other ports or even a hub.
Or maybe another USB device is conflicting. Experiment.

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.
