So maybe you see not only CB or other things have troubles with firmware. Then please let me know.Ī) Emailed Yaesu and asked for an opinionī) Dealer has kindly asked for advice at the importer So 991 owners any ideas? Have you had the same or know someone who did. Just display and buttons around it have decided to stop working. The TX works, A/B buttons, the clarifier, volume all ok. The buttons to the right of the screen do not respond. Reset the radio by switch on with Fast/Lock and remains the same.

Then a DOS like command came from the top left of screen and went around 1/4 way down the page followed by a string like *#ERROR Vertex 1.03#* or similar and the the screen changed to the start up logo of Yaesu. The VFO got slow on change, then the F button and the Menu button didn’t work, or just beeped and did not respond. Programmed some mike EQ parameters into the radio, change the PROC to 8 and some menus in the settings to correspond with the numbers from the supplied list of changes.īut then it started to go bad. Clear, sharp, sounds excellent and nothing appears to be wrong at all. Radio from the box and switched on, all fine and well and receiving across the bands. It appears maybe to be firmware related but when you have an idea then feel free to comment or write directly. If you have any ideas then feel free to send a message and let me know if you have experienced this or know someone who has. When paired with our optional USB-to-radio cable, this software can read, set, and backup settings for a large list of Yaesu models.Here is one for the smart ones, the owners of the FT-991. Our in-house, U.S.A.-based engineers develop a unique piece of software that’s compatible with Windows XP, Windows Vista, and Windows 7, and takes the hassle out of channel programming on the radio’s interface. The lack of intuitive controls on Yaesu’s radios can be easily supplemented by RT Systems Inc.’s amateur radio programming and cloning software. Getting this done with the radio’s on-device interface, however, is quite a headache. These radios can be programmed to function on just a single channel, narrowing communications to just those between a group of professionals, outdoorsmen, or other hobbyists.

The company manufactures one of the largest lines of two-way radios that are used in outdoor environments or on the job in major commercial industries. For radio enthusiasts, Yaesu is one of the most recognizable and reliable brands in the industry.
