WAV log 2015-08-01 6 minutes/7.2MHz

A nice opening to the south on the 1st - which lasted off and on for around six hours. I decided to record the entire band in chunks using a 10 Gbyte file size to test out the new fileplayer and baseband recorder from rtl-sdr.ru. I've only run off the chunk that covers 87.5 to 94.7 MHz and it has yielded 48 identifiable stations plus another three that someone may be able to identify. In the list below I've noted two stations were playing "Hava Nagila" at 09:16-09:17 UTC and another station was playing "Mama Mia". The time span was 09:16 to 09:21 UTC.

The FMLIst log is here http://www.fmlist.org/fm_logmap.php?dat ... &omid=2414 but doesn't contain every station as some frequencies had more than one plausible transmitter. When time premits I'll run the mid-band and high-band recordings.

The key features are:

A waterfall that can be expanded horizontally from it's preset position to occupy most of the screen
Frequency/time control from the water fall - which means you can click on an interesting blip.
Ability to loop the file.
It will play big files and the latest version of the baseband recorder will allow VERY big files if you choose the right format - but be warned they will then only playback in the fileplayer that goes with it. So if this is important choose the SDR# compatible format.
It takes less than a minute to load a 10 Gb fileusing the maximum FFT resolution of 65k and with my 6 minute file has a resolution of around 0.5seconds
At the moment if you play back files not made with SDR# the waterfall is inverted frequency wise which can't be corrected although the spectrum can be by clicking on Swap I/Q
