Think it's the ISY. I turn the power off by plugging the power cable out of that device. The power supply and PLM are still in their outlets and powered on.

I have been using my ISY-994i for several years now with no problems. I am also a ham radio operator. Recently, I began experiencing a strong radio signal at approximately 146.64 Mhz. This signal is strong enough that the it overpowers (makes it impossible to hear) my club's repeater, whose output is at that frequency. Using direction finding techniques, it was determined that the interference is coming from my ISY-994i. Plugging the device out results in the elimination of the offending signal. Any suggestions as to why the interference and how this issue might be resolved?
