Frequency scanner options outside SDR#
Posted: Tue Oct 27, 2015 11:35 pm
You can set up a basic frequency scanner in HDSDR using CSVUserListBrowser and set it up to step through frequencies in the database at user defined intervals. Then with a bit of work in a spreadsheet I can actually back calculate the time/frequency and set it up against the RDSSpy log I've built up.
I have discovered you can use the same program to drive SDR Console - provided you un-tick the option in CSVULB to set the mode. It is just a first look-see and the initial problem is that the scan steps outside the filter bandwidth before jumping to another frequency segment. The really good thing is that SDR-console has a built in RDS data logger - albeit one where you need to save the tmp file before exiting.
The most important thing is that CSVULB communicates with SDR software via a virtual serial port using the CAT protocol - which is supported more completely in SDR console than it is in HDSDR. SDR-console software includes a manual of SDR CAT commands that are supported.
So it should be possible for some knowledgeable soul to get hold of the CAT programme protocol and write a more dedicated frequency scanner that would read the value of the S-meter every time the frequency changes and decide whether to immediately skip to the next frequency or wait for the user-defined interval.
