I have configured satnogs to store the iq file on the ramdisk, so flash wear is no problem.
@kk4yel I am not familiar with linear transponder, but maybe you could check the value of SCRIPT_NAME and/or BAUD and only process (convert, upload) iq files for observations you are interested in?
Edit: you can echo the values of the variables to a file to see what the values are for the observations you are interested in.
