В описании плагина:"совместимость по прежнему только с DSDPlus 1.101"

dimaxa213 Посмотрите Touchstone RF Spectrum Analyzer, возможно подойдет.

Signal Identification Help • Re: Huge Noise!

Does it look like Powerline?
The problem is the Signal are there even with the CB antenna who is on the Rooftop.

SDRSharp.1658 + DSDPlus 2p98 - нет звука (Win10, Колонки для выхода выбраны верно, строку пересоздавал, Брендмауер отключал - помогло) Никто не сталкивался? Откатился на старую версию.

Comment on New Experimental R820T RTL-SDR Driver that Tunes down to 13 MHz or Lower by kjstech

Works for me in SDR# but if I put this DLL in the RTLSDR Scanner program files folder, I get an error trying to tune anything lower than 24 MHz.

[R82XX] PLL not locked!
r82xx_set_freq: failed=-1

Using multiple filters with RTLSDR

If I'm using an AM Reject filter and an FM Block filter, I assume they should be in series. Is there a correct order that the filters should be installed, i.e. Antenna-AMR-FMB-Device or Antenna-FMB-AMR-Device? Does one have to be switched out of the system to use the other either by electrically switching with a relay or physically connecting/disconnecting? Thanks a lot for your thoughts on this. This new 'hobby' is quite fun and addictive. I'm loving it! I've got my first up-verter coming next week to try that system so I'm sure I'll have many more questions about IF, etc. I've been a ham for almost 60 years and I think these new technologies are every bit as exciting as the changes I've seen in that time: AM to SSB, Tubes to Solid State, and of course computers being so necessary for modern day digital communications. It's a fun time indeed. Thanks again.

RTL-SDR Sample Rate versus Sensitivity?

I'm relatively new to SDR, thus this question: My desktop supports the highest sample rate which is why I get more than 2 MHz total spectrum. It seems like with the higher sample rate the sensitivity goes down. Is this a 'trade-off' or I just imagining this is happening? It makes we wonder if there are optimum dependent settings for best nominal performance using SDR# that I should know. (Like use the minimum sample rate as you really need, etc?) Maybe I'm just over-thinking this little trade-off device. Thanks for your help!

Done and quite an improvement in performance overall 🙂
