Re: Strangest thing with my antenna!

My theory is that since I was only using the center conductor, I basically used the 30 or so feet of vertical coax as an antenna (bypassing the TV antenna entirely.) What do you all think? Is my theory correct? No, your theory is wrong. The problem here is that when you connect your antenna complet...

Re: ExtIO_RTLSDR_u8.dll with HDSDR 2.76 + dongle

I am noticing that it looks like the noise floor has moved up almost 30db compared to normal levels using the RTL2832 extio. No, noise floor is exactly the same. The difference is that ExtIO_RTLSDR_u8 uses float 32-bit sample format, while classic RTL2832 uses byte 8-bit format. Software can show d...

Re: R820T3 ?

reception quality is limited primary by RTL2832 chip, so better tuner chip cannot significantly improve quality.

Re: ExtIO_RTLSDR# - custom ExtIO for RTLSDR

1.22 was the first and only version with ExtIO capability but don't hold me to that. You can install SDRuno 1.22, copy folder with exe files to another location and then update to the latest version. In such way you can start SDRuno 1.22 ExtIO (from copied folder) with no need to uninstall the late...

ExtIO version of SDRuno is available here: https://www.sdrplay.com/downloads/

Re: Add on LevelMeter plugin

you're don't need such plugin. Just use HDSDR, it already has level meter and allows to select RMS or Peak mode. Also note, that level depends on selected bandwidth, so when you measure level in CW mode for 500 Hz bandwidth and in AM mode for 20 kHz bandwidth, these levels will be different. Also no...
