Hey, Evan. So, two answers:
1: The wall wart says 2A. To be honest, I just assumed 2Ah, I think I just learned something. Thank you!
2: OMG...you got me a step closer!! I get about 5 watts displaying on my analog power meter that is part of my dummy load. This is the first time anything caused the needle to move!! Saying that, I'm still not getting any power out from within WSJT-X and I am still getting two flashes on the QDX' LED. I'm thinking I am still fighting an audio problem. I have no way of telling if I am receiving any audio via the QDX. I'm connected to a dummy load. I don't have an antenna here where I work.
