FYI : Loss Of COM3 Radio Control AND FIX
For some reason, my PC stopped talking to the 101MP, yet device manager showed the Yaesu com ports there.
So, I deleted the 2 Yaesu COM PORTS in the device manager. Then I reloaded the Yaesu COM PORT files. Just make sure the radio is OFF.
I checked to see if the files reloaded into the device manger and it did. After that, software controlled radio again.
Hope this helps some one .
