Question about UV5R TDR...bug or change?

[LordKaos]

Hi!

Well, I'm new in this forum, I read many very useful threads here, so at first thanks for sharing.

I'm a question about my UV5R (Ver BFB297).

I read in some sites that when TDR (menu 7) is ON, the radio should Tx on the last A or B that received transmissions, so to avoid that, we can set a fixed A or B for our Tx in menu 34 TDR-AB.

...well...mine doesn't keep in the last A/B that received...always remain in the one I select....either if I set OFF - A or B in menu 34. No matter what menu 34 option, always transmit in the one I select with the A/B key.

Is that a change in BFB297 or a bug?

Also I take advantage of my post to ask to be sure....the "recovery" images to reset my version are these?
- BFB297 Reset.img
- BFB297(factory).img
...both downloaded from: Index of /uv5r/programming/CHIRPrecovery

Are them the correct?

Thanks in advance.

I didn't find the edit post option, but I wish to add this info:

Chirp says that my firmware is 1FB297 - HN5RV01, but the radio (power on+3) says: BFB297.

Thanks

BFB297 probably isn't the real firmware version.
You need to use Chirp to view it.
Go to Settings/Other Settings read the version shown in Firmware Message 1.

If you load an image from a different firmware version in the radio you can mess it up.

In the past several years there have been several firmware changes that affect how the TDR-AB function works. There is no way to fix that and no way to upgrade or change the firmware.

Hi Tom, thanks for your response.

Chirp confirms that my firmware is: (line1) HN5RV01 and (line2) 1FB297

Having in mind that the radio says BFB297, should I have for backup purposes the ones listed in kc9hi site? (he only has BFB297)

I can't find the HN5RV01-1FB297.img file.

Thanks again.
