I assume you mean the dummy load AND your power meter? or are you relying on what the internal meter of the radio says (if it has one?)

Dummy load and sure com meter

Sound like a bad unit to me; return for a swap if none of the suggested steps solves the problem

Come on folks, Oppenheimer didn't have this much difficulty building the atomic bomb. I wonder how he would have fared against a Chinese radio?

Could still be coax, antenna, incorrect frequency or tone. Once @OldJunk2 has finished troubleshooting it’s certainly possible that it’s a bad unit, but giving up now would be premature.

Pardon the intrusion, Question 0:  does the screen indicate the radio is transmitting when the PTT is pressed. 

I know on my KGXS20G when the output went dead the radio still looked like it was transmitting.  Only way I could tell was to put my watt meter on the output to find out it was zilch.

Update:

I'm a dummy. I had the TX tones entered into the RX of the programming.

The radio is performing as good as a 20w should. I'm getting 15.5w on high with a SWR of 1.4 to 1 as tested with my NanoVNA

You did good, son. Generally, these issues are self correcting as the user gets more familiar with their radio. Now you will really enjoy the DB20 as its an amazingly good sub-$100 radio.

Glad to hear that the suggested tips worked for you, so that you do not have to return your DB20-G.

I 2nd @tcp2525's comment that it is a terrific radio. I have purchased two DB20-Gs and my original Anytone AT-779UV.
