Hi all,
I’ve just been playing with and adapting the jocover plug-in for SDRSharp and have got it mostly working with the Lime Mini (a few aesthetic and UI related bugs).
Anyway, I’ve been testing by listening on the commercial FM radio band and have chasing some spurious signals. These appear to be worse around 100 MHz (possibly at other frequecies, I’ve only been focusing on the FM radio band).
The original and my adapted plug-in code is closely based on the code fragments in the “LMS API, – Quick Start Guide --”. As such, I’m slightly at the mercy of “LMS_Init()” call (provided by the Limesuite.dll) as at the moment I’m not up to speed on exactly what low level configuration it puts in place.
Here are two screen shots of the spurious signals, one with an attached antenna and one without.
Any ideas?
I don’t see these signals on any of my other SDRs, so I’m pretty sure that this isn’t a local source of interference.
