I understand that alot of devices emit the frequency of 432.000 Mhz, but after a few statements from people that it has been fixed on the newer A4M9 versions, it certainly hasnt.
I did a simple test last night with my radioshack scanner and with the STi XR turned on, the scanner locks on perfectly at exactly 432.000 Mhz with a perfectly clear signal.
Turn off the STi XR and the signal simply dissapear's. Back on, it locks on!
Thought I would share a real life test with you all.
