Ever since I have been operating the STI R Plus with my Redline simultaneously, I have had four separate occasions where my Redline has falsed strongly on Ka 33.7XX (I donít remember the exact frequency).* The areas where it has falsed, *have all been different cities and these cities do not use 33.8 Ka.* Prior to owning an STI R Plus, and just operating the Redline on its own, I NEVER had one Ka false.* Could it be a coincidence or could it be where my STi R Plus (antenna mounted in the cabin on the dash) is interfering with my Redline?* My Redline is mounted on the driverís side visor.
