Re: Using full WSJT-X and FLDigi apps on sBITX V2

 

Joe,

Sounds good.

I just got rid of wsjtx .my own preference, and run jtdx. it seems to be easier to configure. might be a line of code describing the interaction of the digi software in a config file somewhere. replacing the the words wsjtx with jtdx or something. BUT, i would do it only after making a copy of your original SD card with software that came with the SBITX.

That way you can hack until the cows come home and dont have to worry about messing up your SBITX settings and such. All this talk about the SBITX, im going to have to pull the trigger and get one later.

I have 6 of the 64gb SD cards with various software loaded with different ham stuff like fldigi, jtdx, logger programs, and such.Dragon OS, Kali linux OS, Bullseye OS,Ubuntu,Fedora,and retroPI. ubuntu is the easiest to get ham distros downloaded from repositories ,unless you use Dragon OS. Dragon OS has a buttload of software for logging,digital modes like fldigi, wsjtx,jtdx,qsstv,and many more already written into the distribution.

I use my PI 400 with all the above software, but particularly like ubuntu,and dragon distros. I run digital modes on my PI 400 with Dragon OS .2 cables from the PI to my Ubitx.Then when tired of hamming and want to Shortwave listen or use a scanner for police calls, i insert the rtl-sdr along with my SDRPLAY receiver and use sdrtrunk, or some of the other many sdr receiver programs built in with Dragon OS.

I also know its not super accurate, like a spectrum analyzer, but i use my PI 400 with the SDRPLAY to analyze my transmitted signal off my QRP and higher powered rigs,using attenuators on the SDRPLAY input. then check for harmonics levels. just old time math to find the harmonics 2nd,3rd,4th and so on harmonics,and look for a signal where it shouldnt be.

?I know, everyone ,its not a spectrum analyzer but my stupid setup seems to work for me. And i have fun learning about filters and such.

Anyway, everyone, enjoy the software.Remember there is plenty of choices for base PI OSes. Im assuming the PI ,with software ,controls the parameters of the SBITX.

Anyway Joe,

Good luck on the SBITX with digimodes and maybe we can work each other. I like to work the warc bands since traditionally there is no contests on them. Just wide open spaces.30 meters,17 meters is my favorites, and non warc bands 80,15,10 meters.

You can also reduce the attenuation of the audio to the loopback. Change
in sbitx_sound.c:

#define LOOPBACK_LEVEL_DIVISOR 8

to something like 4 or 2.
