SDR Console RDS logfile catches Georgia (and Azerbaijan)
Posted: Sat Sep 26, 2020 10:47 pm
Whilst putting my new PC through it's paces and seeing how far I could 'push' SDR Console I decided to check how sensitive the RDS decoding was by playing back an archived file that includes reception of two FM stations from Azerbaijan. (Previously mentioned in the other forum).
So as per Jim's (G0FE) post on the subject, I was running 10 VFO's simultaneously, and capturing the RDS codes. I had gone through this file (so I thought) exhaustively.
But on the next to last block of frequencies covered - SRD Console logged a PI code of 0951 on 95.1 MHz, as well C201 from Azerbaijan on 93.0 with PS: AZER FM and the same pi code on 94.6 (identified as Azerbaycan in a station announcement).
FMList.org identifies that as a Avtoradio from Tsiblisi in Georgia. (i've attached a screen shot) As an aside - the date stamp is wrongly reported by SDRConsole because I copy/pasted the file to an archived folder on another HDD drive. For some reason Windows puts the original file date in the "Date modified" and the date copied becomes the "Date Created". This is a file recorded on another SDR program. The date was 16 June 2020.
The section of the RDSlogfile showing is of interest. The entry at the bottom showing PI code 0951 was created when 10 VFOs were running.The one at the top was with just one VFO to see if there was any improvement in sensitivity. Both lines on the logfile show that the pi code was captured three times. (The 2nd line up - PI code C201 is Azerbaycan Radyo from Azerbaijan).
I'm busy processing files from the 23rd May 2020 in blocks of 10 frequencies. Multiple VFOs logging RDS simultaneously is the best thing since RDSSpy was released, especially after Simon has tweaked the sensitivity of the decoding algorithm.
