Not any mentioned in this group - a web search should turn up something.
I did get a

It works, but I never got its usage figured out, for making sense of the X5105's I.F. passband display.? With some development work, it might be able to show you what frequency you're on, but I couldn't.? It did seem like the I.F. passband display shown by the Nano had the spectrum 'reversed', with the higher listening frequency at the left end of the spectrum display.? I think that there must not have been enough signals on the air, at the time I was trying it, to see any useful indication of active stations along with the background noise.? I could see some signals, and see them move when I tuned the radio, but I could not tell which visible signal was the one I was hearing.? I don't know the I.F. passband width,either, to see how wide the spectrum display bandwidth would be, and how much of a ham radio band would be on the pan display.
Since then, I got an RSP1a, but I haven't tried that with the X5105.? It shouldn't make any difference, though - what I (or someone) should try is to use a cheap SDR dongle with the nice programs meant for use with the RSP1a type SDRs - they're based on the same basic TV receiver chip.? Hopefully I'll have a chance (that means "get around to") trying the software like HDSDR and SDRSharp to see the X5105 I.F. output.
For anyone else trying the SDR panadapter, don't forget to order an SMA-to-MCX connector adapter to fit the radio's I.F. output jack.
