After running WSPR on Ultimate 3s, I have been running on 2 QDXs for quite some time on WSPR. One of the significant benefits of the QDX (for me) was running the timing off of my computer versus having a separate gps module on the Ultimate 3s.? I just finished building a QMX and am curious as to why the timing is off of gps versus being able to sync via a computer.? And I really like what I am seeing in the QMX and looking forward to "playing" with it a lot more! Cheers - jeff, AC7IJ
