My QDX is dead. No transmit and no receive.? I had a problem with my
coax connector at the antenna and it was seeing high SWR (about SWR 5)

it at 11v to be on the safe side. But it still got fried.
Most probably you fried the finals (and maybe the driver chip). It's cheap
to repair, you could give it a try.
I won't be repairing this one not because the unit didn't perform well
when it was operating but because 5w on FT8 from VK is not enough power
for reliable DX contacts on 40m, which is where I like to operate.
Have you tried the QCX PA?
Here's how it performs in my QTH -- multiple contacts across Europe and
a few DX-es -- not bad given that I work it only occassionally (1 hour
a week or so):
