When they ask me, "Why don't you use DATA-USB?" -
My answer is:
It is much easier to setup everything in the SETUP MENU, and thanks to these settings you can easily work with other digital modes RTTY, PSK, CW in the DIGITAL MASTER 780 from the HRD "package". If you want to switch to voice communications, above the 40m band you don't need to change anything except the frequency.
The only difference I noticed is that in the USB mode the filter width is from 200Hz - 1800Hz (narrow) and 1800Hz to 3200Hz (wide), while in the DATA-USB mode it is 50Hz to 500Hz (narrow) and 500 to 3000 (wide) .
