After my 6300 has been on for a day (give or take) the transmit audio on FT8 becomes very distorted. Turning the rig off and on fixes the problem but it shouldn't happen in the first place. I have noticed the problem in the older version of SmartSDR and the latest update as well.
Yea this bug has been around for a very very long time so your not alone, you don't or at least I don't have to turn off the radio to fix it, just kill DAX and restart DAX takes care of it for me. 73's Bret
I have had this problem since I purchased my 6500. The rig works perfect at my base station, and is wonderful to operate. But the distorted audio is a real issue since everyone tells me how band my audio sounds. I wish I did not have to tell people that Flex Radio has not solved this problem. I may need to sell my Flex and move to the new ICOM radio that just came out. Still waiting for reports how it works over the internet. Please, if someone has a solution I would really appreciate any help you could provide. 73, Hank Wolfla K9LZJ, W9VW, VK6AW
