[hpsdr] CW sidetone through speakers on PC instead of Headphone on ANAN SDR

[Ken N9VV]

The technique I used to make mp4 movies is to simply attach a line 
isolator from the rig Headphone jack to the Line-Input of the PC. The 
Line-Isolator simply removes any hum caused by ground loops. I can 
easily hear and record the sidetone from the rig with no competition 
from a delayed sidetone in the PC.
