My KX3 cuts off input if the mic gain is set too high. Maybe same issue for your K3?

One thing I can say is that you must have 4 bars of ALC showing with the 5th bar flickering. If you have no indication on the ALC meter, that means the K3 is not getting enough audio from your software application, and you will have to find out why - perhaps the "power" slider in the FT-8 application is set too low. You might want to take a look at the data mode setup on my website www.w3fpr.com. In the left column scroll down to the last entry and click on it to get to the article. 73, Don W3FPR On 1/20/2018 12:12 PM, Larry Libsch wrote: > Group, > > I am unable to get my K3 to TX any RF when set up for FT-8. > Hardware is K3, Behringer U-phoria UMC202HD USB sound card running on > WIN XP with most recent version of WSJT-X software.
