Good afternoon

I have a Super Jopix 2000 and the problem i have is when i'm transmiting in any mode or frequency, the tx power stars to go down.
Can someone help?

What's the voltage on driver/final when you observe that behaviour?

Hi, can you explain better?
I don't understand much about the matter.

Measure DC voltage on driver or final transistor on TX. Write us it's value.

What brand#/model number of the Power Supply are you using to operate the radio?

Good afternoon, sorry to replay now.
I send a picture from my radio and my power supply.
The power supply sends 13,8v all ways, my antenna its a Black Pirate with 1:1 swr.
"Measure DC voltage on driver or final transistor on TX. Write us it's value." - Can you tell me how do i do it?

Best Regards
