Hi, I'm looking to amplify a 120kHz signal generated by my SDR by 30dB if possible. Unfortunately, I'm a computer scientist with little to know RF experience so I'm kind of struggling here. I was thinking about an op amp setup but don't really know how to approach this. I found several schematics online, but they all have different values for capacitors and resistors. How are these calculated? Are they dependent on my frequency? I'd love to learn, but I'm having a hard time getting started.

Hi, does anybody know where I can get older versions of nSonic? My CX is running on 4.0.3.29 currently, I could update to 4.5.something I believe but I can't find an older version on nSonic compatible with either. I can only download nSonic 5.3 which doesn't work with my device unfortunately.

Thanks for the help!

So I´ve found a (paid) site that provides sheet music and I´m looking into ripping the full site in their trial period. I´ve got a small bit of programming experience but I need some pointers in the right direction. My current train of thought is:

1. The URL to access the pieces is: url.com/languageidentifier/id/[Unique ID of the piece]/file.aspx Everything except [Unique ID of the piece] is the same for every piece.
2. The sheet music comes in two (embedded) formats. Either PDF or MusicXML. When viewing the network activity using the Firefox Network Monitor the page makes requests to wellknownsheetmusicpublisher-pdf.amazonaws.com or wellknownsheetmusicpublisher-musicxml.amazonaws.com.

I‘m looking at buying a used MB pen but the seller doesn‘t know what model this is and I only know much about Lamy pens. Could someone please help identify this pen?

Thank you all very much!

Edit: The one thing I know about this pen is that it‘s a cartridge filler
