51  I purchased 5 rt21 radio's and the disk to program them with the cable; but it does not work with windows 10. can you send me a link to the correct software?
Please download RT21 usb driver and RT21 software from Retevis official website: http://www.retevis.com/resources-center/ Attached a photo for you reference:
52  I just purchased 20 H-777 radios, to add to the already 30 I have. Of the 20 new ones, only three would open into programming mode. I have 17 little bricks that I can't program. I'm using the cable you provided, along with the same computer and software that I used on the other 30 H-777 radios. I'm using the same programming steps as the other 30, yet only 3 of the new ones would receive the new program flash. Do I need to return these? I need another 50 next year, so I'm hoping there is a simple solution.
Hello Chuck Marsalisi, Please download H777 usb driver and H777 software from Retevis official website: http://www.retevis.com/resources-center/ Attached a pic for you reference, then try to program in H777 software

55  I bought 6bay charger C9042A no instructions inside, can you e,mail to me please? Marty

56  Is the firmware update still aviable my firmware isD003.008 and cp ver vo1.30 can not find update
Hello Paul, What's wrong with your RT8? The situation is if the firmware is not well-operated ,the radio will easily die completely, it'll be a useless radio. Then the radio should be back to China Factory to be fixed. But kindly note customer will afford all the shipping cost. So if the radio has been used normally, we don't suggest any update on it . Just please you know the risk in advance.In addition, relative blog for your reference:http://blog.retevis.com/firmware-update-rt3-rt8/ for getting the step, and getting you radio version. Thanks.
57  when programming in frequency like 270.600, or 127.800 when i push the last 0 it says "cancel" is it possible to fix this? cheers steve
Please note: RT5 frequency is 136-174MHz and 400-520MHz, you can programming in this range
58  ho acquistato coppia di rt-5rv e usa solo lingua inglese e chinese , non italiano su menu14. Come si puo' cambiare lingua ??
Mi dispiace per ora che abbiamo solo l'inglese e il cinese, ma lo faremo in futuro.
