I pretty much did everything that Joe VE1BWV suggested for JT65. ? One additional note... one of the purposes of the 600/600 ohm transformers is to isolate the radio ground from the computer ground. ?To do that, ?the common (ground or sleeve ) connection of the 3.5 mm audio jacks that connect to the computer should not be connected to the radio ground. ?Since I built radio in an aluminum chassis, ?I cut out a hole in the chassis and mounted a small plexiglass piece over the hole and mounted the 3.5 mm jacks on the plexiglass to isolate them from the radio chassis.
I intended from the start to use the radio for JT65 only - ?since I only run about 2 W and wanted to get away from the "big rig" since I leave it on much of ?the time and log all the received call signs ?to PSK Reporter even when I am not actually trying to make contacts - sort of a beacon. ? I use the WSJTX software from Joe Taylor.?
Hope this helps
