Re: [chirp_users] offset precision
Greetings,
The error of 110 Hz doesn't seem very significant but the 1,550 Hz error could cause some operational problems. Do the two different error levels relate to different shift directions?
I recently programmed some channels into a UV-5R+ manually and read the memory bank back with Chirp. There was no error in the offsets as read by Chirp. However I cannot use menu 26 to check the offsets in /Channel Mode/ as it always reports zero. I confirm the proper offset by using the reverse function which displays the shift but of course with 1 KHz limited resolution.
My firmware version is BFB927. I wonder what firmware version you have? (Easy to determine by holding the #3 key pressed during power up.)
I also wonder if there is a list of known problems with different firmware versions posted somewhere?

Hi,I've just set up CHIRP and downloaded the memory channel list from my Baofeng UV-5RV2+. I notice that the offsets on my saved channels are not exactly what I expected to see.
For the channels where I have set the offset to 000.600 in the radio, it's showing 0.601550 or 0.599890 in CHIRP. For the channels where I have set the offset to 005.000 in the radio, it's showing 5.001550 or 4.999890 in CHIRP. My question is, do I need to make any changes to these offset entries before writing the image back to the radio?? Should I fix the entries to show the exact frequencies that I entered in the radio, or are the shifted frequencies correct? As a side note, I see that the default offset for channels that I have not set up are exactly 0.600000. I'm afraid to write an image back to the radio that could cause a problem so I thought it would be best to check first.
Thanks.Ed

Unless your radio is about 3 years old, it is a safe bet that your radio does not have BBF297 firmware. Ever since BFB299 firmware (the version after BFB297) was released, all UV-5R radios (and its many variants) since then all report BFB297 in the [3] key + Power-on message (well all except BFS-313 which reports BFS297).
So pressing the [3] key while powering the radio has been of no value for determining a radios firmware version for quite some time. The only way to determine the "real" firmware version of these radios it by using CHIRP (Settings -> Other Settings).
I also wonder if there is a list of known problems with different
firmware versions posted somewhere?
A list used to be maintained on the miklor.com website. Its maintenance was pretty much abandoned because there were became so many firmware version variants and Baofeng was making changes to the firmware without bumping firmware version.
For example soon after the N5R-20 firmware was released, a BEEP bug was discovered. this bug was fixed but the firmware version continued to be N5R-20.
