I can not get the com ports to come up when I am trying to program the radio can you help me out with this??
Have you installed and run the USB driver on your computer? You can download the driver on our website https://www.retevis.com/rb89-high-power-gmrs-radio-with-bluetooth-headset-us
I wished that the programming software would allow changing frequencies. This is a real shortfall when trying to match other radios RT21 that were setup for 3 channels only.
When the radio is scanning, is there a way to turn off the channel display so as to save power?
The Bluetooth works very well!
