There have two versions of Retevis RA25, GMRS and UV dual band version, as we all known, GMRS is only for US users. Today, let us learn how to program the RA25 UV band mobile radio. 

Where to download the RA25 software?

If you set a repeater frequency, it also support to reverse the frequency. and there have 3 power levels to choose.  Low power =5W , middle power=10W ,and high power =25W. 

Here another useful setting which you may want to enable and depending on your usage would be "Busy Channel Lock-out", if you enable this, the radio will not be able to transmit while there is a signal being received, but this is quite useful if you want to ensure that you are not key over anybody else that is talking.

On the top right corner, there have "TX OFF" and "Scan Skip". The Tx off if enbaled will completely disable transmitting on this channel. for RA25 UV band, the transmit frequency from VHF:144-146Mhz, and UHF:430-440Mhz, but can receive from 136-174Mhz, and 400-480Mhz. If you set this is only a receiving channel, you can enable the "TX off". 

If enable "Scan Skip",it will remove this channel from any scans.
