BI6OIE Jason I also experienced issues with A/B band hopping, where the FT8 transmitter would suddenly switch to a different band... After updating to the latest firmware in September, the problem was resolved.
Jason BI6OIE I also upgraded the firmware later, but I forgot which month it was. Also, I added a large magnetic loop, mainly because the antenna was out of tune, and I used a GP with an active antenna. The large magnetic loop really worked!
