Re: Audio Breaking up with Rocky V3.7 and RXTXv6.1
- You might also try to shrink the vertical size of the Rocky window. That will help minimize the software processing load for the display. That works with my XP system.
I also found that I could not run a separate logging program with Rocky on transmit. It would chop up the CW signal to be unrecognizable. When I stopped the logging program, the CW then sounded normal. So stop any other running programs if you can.
I am running a dual core ATOM processor with 2G RAM and WinXP Home.

I assume there are processes and services causing interrupts that I can turn off but I don't really know which ones I must have running.
