Checking the obvious here, but does your display indicate "S" when TDR is ON?

[MENU] 007, [MENU], scroll to ON, [MENU], [EXIT]

The display now shows the letter "S" to the left of the display. This indicates the radio is in Standby Mode, monitoring both frequencies or channels. As soon as an active signal is received, the "S" is hidden, and a flashing triangle will indicate the active frequency or channel.

Now, if there is an active transmission on either of these two frequencies, the green LED will light, and a flashing triangle will indicate which frequency is active.

Even if you've toggled the [A/B] button to monitor the frequency on Display B, an active transmission on the Display A frequency will be heard and indicated with a flashing triangle.

When the active transmission ends, the green LED will go dark and the flashing triangle will not be displayed.

Not sure if Menu Item #34 - TDR-AB would affect the dual watch feature. I found a discussion regarding TDR-AB that indicates it simply locks in one specific frequency or channel for transmission, while still allowing dual watch function:

The older radio software included a Menu Item that could "lock" transmission to a specific frequency or channel, even when monitoring two different frequencies or channels with Dual Watch Mode. The older software featured a Menu Item #34: TDR-AB. The option allowed selection of either Display Line A or B as the transmitter frequency or channel. In both new and older UV-5R radios, be sure to turn TDR (Menu 7) off before attempting to manually program a duplex memory channel into the radio. - KG5SQJ Bob Ballard - groups.io/g/w5pc/topic/fyi_baofeng_uv_5r_and/24189497 )

However, Menu Item #34, TDR-AB, does NOT function on UV-5R radios built after 2014! The newer UV-5R radios include Menu Item #34, but it DOES NOT WORK! It does NOT lock the transmitter. Both frequencies or channels are monitored, but the transmitter frequency depends upon the A/B toggle switch.

Good work, Steve! That's good information. 73!
