Turns out that swapping the coax, changing the CB antenna mount for a new (MUCH beefier 1/4" stainless one), moving the antenna 12 inches to the left, and adding my dual band antenna made absolutely NO difference to my CB SWR. After I dialed in my SWR meter, I was immediately at an SWR of 1.1 on channel 10 (where I tune)
Now I can start programming the various channels into the 8800. Unfortunately the cable that I picked up from NTF didn't come with the CD-rom for the software
