Re: Help withRTL-SDR & SDR# No Device Selected error

Your "balum" is designed for HF. It's effect at VHF/UHF is probably unknown. Try direct conversion of HF signals and see if you receive anything. If you have a 2m antenna, try that for 2m reception.

Re: Help withRTL-SDR & SDR# No Device Selected error

I downloaded usbview.exe from Microsoft in a zipped troubleshooting package that they offer. I have since learned that .exe files should be scanned for malware before use because .exe files are an easy way for malware to be spread. I don't know about the above URL - it may be safe or not. Sorry that...

For those of us (hams), more interested in HF (3-30 MHz), an up-converter is preferred to an amp.

Re: Extreme noise at reception

What is your noise level on a CB receiver? What is your noise level on a short wave receiver? What is the source of the noise - local or skywave? Are you in direct sample mode?

Frequency range can be extended down to 100kHz or lower with the Ham It Up,..." https://www.amazon.com/NooElec-NESDR-S...

Re: HDSDR and SDRSharp cannot find RTL2832 USB

At one point in getting my V3 working with SDR#, Windows 10 asked for my permission to allow SDR# to receive the data stream from the V3 dongle.
