Here are some little programs that it is said generate 1644 and 2448 J-Test files.
They seem to only run on 32 bit windows, but they seem to run well enough on my VMWare 32 bit virtual machine under 64 bit win 8.1.
Just to make life easy for you, I included the .wav files that result from running the programs along with the program exe files and their source code
I downloaded these from who knows where last year, but google says that they disappeared from the web.
For people who want just the data files in a most compact form, here are 44, 48, and 96 KHz versions of the file as FLAC files in a ZIP file:

It will not always create 96 samples in the upper and lower rows of the square wave.
