SdrDx Any Helpful Tips for A Newbie?
« on: November 11, 2013, 2050 UTC »
I've been trying HDSDR and SdrDx with my AFEDRI and I was wondering if anyone using SdrDx has some helpful tips.  I've been reading through the documentation but I'm not understanding some of it.

For example I really do not understand the purpose of or how to use the screen in the lower right hand corner.

Also, I posted a comment on the developer's site asking about scheduled recording. His reply

You can drive SdrDx’s recording facilities from a Python script; any schedule you like. Very simple to do, presuming you know a little bit about python.[\quote] Although I would like to learn Python I would like a more user friendly option.

Thanks,

Kent

The scope screen in the lower right can be used in many ways. I really only use one of them - the CAR button option to show the carrier frequency of a received AM station. So I can't offer any hints for using the other modes.

Likewise, the CAR window is used most.  Sometimes I use the WTF window (Not what you may think...) for placing notches or seeing where some sort of noise is distributed in the audio. I can then taylor the audio settings---LPF or HPF, BW etc to minimize undesirable noises etc.
