Baofeng UV-3R+ Repeater Offset Broken

I was recently in search of a small, low power HT that has dual band (2m/70cm) capability. A bit of interwebs reading pointed me in the direction of the now discontinued Baofeng UV-3R+. For less than $25 each, including slow boat shipping from China, I grabbed a pair from Ali Express during the recent 11.11 sales.

The form factor of the radio is just right for my XYL’s purse, so she will carry it as an emergency radio. She also has a tiny Puxing PX2R purchased years ago via eBay, but it is UHF only and we wanted dual band capability so that she could hit KC2GOW’s new machine near her work QTH.

However, programming via software was quite difficult. It turned out that both the native software and CHIRP fail to adequately handle repeater offsets. A bit of reading came up with a couple of references to using .006 MHz rather than .600 as the VHF offset and then using .05 rather than 5.0 as the UHF offset. As you can see, the value has been shifted two decimal places to the left. Anyway, this is how it works with CHIRP.

Even worse is Baofeng’s own software, which requires entry of separate transmit and receive frequencies, rather than an offset. So, for a repeater which transmits of 146.76 and receives on 146.16, the Baofeng software needs a transmit frequency of (146.76 – .006) or 146.754 MHz.

OK, the radio is cheap. It is worth what I paid. But it is no Yaesu or even Alinco. Caveat amateur!
