The amplifier is the black widget mounted to the board with screws, above the metal can. ( The RF module)? Other than a really awful short circuit of some kind, it's unlikely the 2.5mm serial port jack could prevent the unit from powering up. I suggest you send me your MTT4BT, power/serial cable. and USB-2.5 cable, and I will check everything out and do my best to make them run according to Hoyle! My shipping address is:

Allen, ???? Thanks. I have been using the V3 "Hershey Kiss" antenna that Byonics sells: Nagoya UT-108UV.
The antenna is placed on a piece of sheet metal for ground plane.
Have not touched the blue potentiometers inside either.
Any reason this would impact the unit not powering up when the 2.5mm connector is plugged in/connected to the computer?
Honestly I'm feeling like I got a bum unit here. All power sources have been fused, no fooling around in the programming, ect.
For the test, I assume the amplifier is the silver rectangle on the right-hand side in my pic below?
