Ok, it sounds like the Raduino isn't providing a signal. Make sure it's correctly connected, there's a wiring color oddity between the two cables.
I'm also assuming you're working on a BitX40 and not a uBitX, right?

The PA voltage is going through the switch as well. I measured from the
DC plug to the base of the positive that feeds the PA. It does double
when I click PTT, but that's it. I'm set on 200ma so I'm assuming I'm
getting like 5.6 - 5.8 milliamps through it when I press PTT and 2.6-2.8
just idle.
Also at 2 feet from the receiving rig, the dummy load is sufficient. No
need for an antenna.
With the antenna, do you receive anything on the BitX?
Vince.
No. I didn't hear anything, but the antenna was on the floor. I tuned my
HF rig to a really strong signal and tried to find it using the Bitx40
but it never picked anything up.
