I am fairly familiar with Steve's issues. I have thought jumper/pigtail for a while, but pretty much ruled that out when then did the unidirectional tests and both links jump to 12M. Any thoughts on which cable may be the issue? They did realign the antennas recently. I know they were supposed to do both azimuth and up/downtilt alignment.
