Screen reader compatible rtl sdr apps
I am blind and recently got myself an rtl sdr blog v3 to use for radio astronomy. Before attempting to set up a proper dish and feed line for it I thought I’d attempt to try out the antennas that came with the kit I got. Unfortunately it seems as though the most popular app for macOS is gqrx which doesn’t seem to work well for me, it doesn’t seem to let me click or select things with my screen reader properly meaning I can’t even select my device on the first screen. I tried out cubic sdr as well but it also doesn’t seem to work, it just freezes up and doesn’t let my screen reader navigate properly.
I tried out the command line tools with some more success. rtl_test reports the device is plugged in and working properly and I can get rtl_power to give me output though it’s in a fiddly csv format that I’ll need to write a script to make useful. rtl_tcp starts the server which seems to work properly but I’m not sure what apps really work with it beyond the ones I’ve tried. And I can get some feedback out of rtl_fm when setting to local radio fm frequencies though there’s lots of static so I can only make out the odd word, and testing am frequencies, with the am option set and -e direct flag, gives no feedback at all, not even static. It seems like rtl_fm also doesn’t document all of its options as I’ve seen reference to flags like -l that don’t give an error when I use them but don’t appear in the help output or man page and don’t seem to actually have an affect on the output.
Are there any other blind rtl sdr users out there and if so, what apps are you using to use your radios?
