Hi all. I purchased a baofeng a couple of years ago as a backup to my Anytone. I wanted to add some frequencies to it this week, which I haven’t done in a couple of years, and it won’t communicate with my windows PC. It used to work fine with the programming software. The only thing that has changed is my computer has had Window updates over the years and now running Windows 10. I saw some info about old divers or cables not working on newer Window versions? Any thought on fix? Brian W2BRM

First let me say thanks for letting me join this group. I have 2) UV-5R's and 1) BF-R3 (tri-band) and a couple of other Baofeng/BTECH mobiles. They all have their quirks, but for the most part operate VERY well! I bought the BF-R3 as it was CHEAP, especially for a Tri-Band (2mtrs, 1.25 mtrs, and 70 cm). So I went to program it using CHIRP (they don't make OEM software for this radio, so I had no choice), but I found out the the model BF-R3 doesn't exist in ANY of the 3 manufacturers that make/sell the Baofeng products! So then I went back to the CHIRP website and found a paragraph that says to use the "Radioddity" model "UV-5X3". It said UV-5xx, so I tried it and sure enough it read the radio. Then I put in several 2 mtr, 220 MHz, and 440 MHz repeater pairs and uploaded them to the radio. IT WORKED!! So I finished loading all the repeaters/frequencies I wanted, flashed them to the radio for the most part everything works fine. There are a number of 220 MHz repeaters listed for my area in Repeaterbook.com, but as this band isn't used much, a LOT of them are no longer on the air, so I have to continue to hunt for working ones, but that's neither here or there. I then took one of my UV-5R's and read it using that same set up and it read it just fine. It even took the same database. But when I tried to use the radio, 2mtrs and 70 cm worked just fine, but the 220 band wouldn't transmit. So I went back to the CHIRP site and found that you have to go in and change the radio's VHF frequency span to: VHF Lower Limit - 130 MHz VHF Upper Limit to 250 MHz The VHF Upper limit frequency defaults to 177 MHz, or something like that and it MUST be changed. It transmits/receives just fine. BUT, and this is a BIG BUT: You MUST switch to a TRI-BAND antenna!!! Do NOT use the antenna that Radioddity sells as it is NO GOOD!!! I know from personal experience that their antenna is BAD on both 2 mtrs and 220 MHz. It works great on the 70 cm Ham band!! It doesn't work well at all on GMRS frequencies either, just the 440 MHz band!! I inadvertently purchased one through Amazon. Whe I received it, I noticed that it said "Radioddity on the packing (not a company known for quality products). It was NOT what they advertised, so I read the reviews of it and there were NO good reviews. So I decided to put it on my work bench (I'm the Radio Tech for our County) BEFORE putting it on my radio. Sure enough, that antenna was CRAP! The reviews were 100% accurate!! I did some research and fount that Nagoya makes a tri-band antenna (NA-320A), which I purchased and they work GREAT!! I have the instructions on how to convert your UV-5R to a Tri-Band radio, if anyone would like. Just email me @: KC7CJO@... The more Hams we can get on 220 MHz, the more popular it will be come!! Let the FUN begin! 73's! Rod KC7CJO

Some of you may have already attempted to program 220 freqs on your UV5R*3 with Chirp which resulted in permanently disabling the radio's 220 ability. Here's what you must do. #1, You must use the latest version of Chirp requiring Windows 10 or later on a 64 bit machine. You can not use Chirp Legacy! #2, Set Chirp to Radioddity UV5RX3. Download from the radio's it's factory image file and save it. #3, Inter all the frequency channel data you want. #4, Selected "advanced settings". At the bottom of the list read "Range Override Parameter". The factory setting is "default". Change this to "atyourownrisk". You can not paste it in.(see attached) #5, Upload data to your radio. If you have a second radio to program you must repeat step #4. #6, Save as: Radioddity_UV-5RX3 UseAtOwnRisk The "Range Override Parameter" will go back to "default" after every download, and it can not be save. Notes on 220 in other Baofeng UV5's: Contrary to what you have seen on youtube videos, changing the range of a UV5R will not allow operation on 220. While the radio may accept programming on that band, it will not function. Of the 5 radios that I did this to, only one had measurable output power, and it had heavily distorted audio. Earlier UV5RA3 versions specifically built to included 220 do not appear to require the special care outlined above. I have programmed them with Chirp legacy without issue. You will not see the advanced settings menu in Chirp Legacy that you have in the Windows 10/64 version. Dennis Starks Military-Radio-Guy KB?SFP
