I have also ordered one of the RA25 units along with the programming cable. Retevis said it would take 4-5 weeks to get to me under regular shipping. I have been playing around with the software and here is what I have noticed: After extracting the files, you get 2 default files along with the program itself. One default file is for the VHF/UHF version of the radio the other is for the GMRS version A9198A-RA25-Codeplug-210116.dat A9198B-GMRS-Codeplug-210116.dat Loading the VHF/UHF version, you can enter the frequencies you want. Loading the GRMS version, the GRMS frequencies are already entered and you cannot change them. You can add a channel name, the CTCSS/DCS codes and most other options, but not the frequencies. Also the FRS only channels (8 - 14) are not listed. ScreenShot 1 shows the VHF/UHF version. Double clicking the” MORE >>” on a CH number will bring up the Channel Edit window. When you type in a frequency, you will be able to edit all the info in this window. ScreenShot 2 show the GMRS version. ScreenShot 3 has the Channel Edit window. Notice that the Frequencies are already there and are grayed out. As far as VFO, in the GMRS version you can't add frequencies. The CTCSS/DCS codes in the GMRS version are the same in any other Retevis GMRS radio. I have been using RT76 portables from Retevis and did change the codes for my situation, but if you are using the radios in Simplex mode, it's “out of the box” communications. Once I get the RA25, I will do an update to the forum. ,,
