Frequency scanner options outside SDR#

Post by DaveB » 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.

Thanks again, Paul - NN4F

Hi Paul,

SDR console includes a pdf file listing the CAT commands available in SDR console. I found a file on the web that could be useful.

http://homepage.ntlworld.com/wadei/HOWT ... s_v1.2.pdf

the problem for me is that the HHD serial port program comes up with an error message "you need administrator privileges" - I AM the administrator Win 8.1 user panel says so! Grrrr!

It would be nice to have a simple way of typing in a CAT command manually and see what comes back. I'm sure there is scope for someone to write a simple frequency scanner using CAT commands provided that SDR console has (or can provide) either the state of the squelch of the S meter reading - but it's beyond me.

I am using SDR# for scanning because is the best program for me.
Of course there is one of the older versions (1361) because new versions do not support superior plugins from Vasili Beliakov.
Frequency scanner and voice recorder.
On my laptop maximum speed of the scanner is 142 MHz/s and think not many people need some faster.
