“Hello operators A few operators have left comments with concerns about the reported USB clicking on the Yaesu ft-891. Apparently one or more operators has had issues with sounds interfering with RX, while the radio is connected to a computer using CAT control. To take the issue a step further, some operators have said digital mode operations with this radio are impossible.
Let’s call them out to see if that’s true! https://youtu.be/HwmZzOrUkP4 As you’ll see in the video, the closest I was able to come to replicating the USB clicking problems, was by using the worst possible USB cable that I could find. That cable came from China via eBay! Moreover I’m also using this radio with PCALE, wsjt-x, fldigi, FL rig, aprs messenger, and have not been able to find any reason why this radio would not be less than magnificent, for digital mode Communications on HF. This really makes me speculate about ARRLs “thumbs down” of this radio. what I’ve seen so far, this radio has a magnificent receiver, excellent filtering, and comes in a form factor much smaller than the Icom 7300 or 7200, making it a viable field radio. I hate to ssy it guys, but this radio is truly amazing! 73 Julian oh8stn”
