I recently tried my new RTL-SDR Nano 3 "dongle" connected to the I.F. output of my X5105.? It worked out nicely, and I could see at least 1 mHz of bandwidth.? I was looking at the AM Broadcast Band and could see carrier spiked on just about every 10 kHz channel.? And I could hear the audio too, slightly delayed compared to the sound from the radio's speaker.
The Nano 3 came in a "kit" from Nooelec, and I got it from Amazon for about $35.? The kit includes a short cable with SMA connectors and an MCX adapter for the dongle.? I had to buy another MCX adapter for the radio end.? It also comes with adapter cabling for connecting to a phone and to a charging system at the same time (there's a USB "Y" adapter too).
The little sdr dongle is hardly larger than a postage stamp.? But it does get very warm - it comes with a small, stick-on heat sink!
I haven't found enough other band activity yet to get a good idea of what it might do for ham band operation, though
