A few catches from the indoor spectrum grabs

I am enjoying using my indoor spectrum capture set-up for recording endangered shortwave stations. The set-up relies on my earlier work on mitigating urban radio interference, caused by being in a busy apartment building in London:

I thought I'd share a few of the catches I have made so far. First up, some good music. Here's an atmospheric set from the Voice of Greece on April 21st, 2016 at 2340 UTC:

A beautiful set of qawwalis and ragas from All India Radio Urdu service, recorded on May 23rd, 2016 at 0055 UTC. I especially like the song at 5 minutes 30 seconds into the recording:

I have also been fortunate to catch some more distant transmissions, such as Radio Thailand on 13/06/2016 at 1900 UTC:

A nice bonus that I didn't expect to show up in the spectrum recordings was the Voice of Turkey's English language broadcast on 04/06/2016 at 0300 UTC:

Finally, propagation from Cuba hasn't been great lately and I certainly have much clearer recordings of it from indoors than the one below, but the SDR# software did a fine job of pulling it out from the noise:

Overall, this has been a fun little project and given that I can make these recordings regularly (unlike the trips to my local park), there is a steady stream of gems to be extracted from the radio static and explored.
