The 2007 Zaon I had wired to my ASW-19 battery did not produce static on my Becker radio. The 2009 Zaon I wired into my LS-8 battery did make static on another Becker radio. As a sanity check I tried the 2007 Zaon in my LS-8 and found there was no static. For what it's worth...

I had a problem with static in my radio with the Zaon connected to the ship's battery (squelch would go off). As a result, I went back to feeding AA batteries to the Zaon. Are those reporting not having problems with the Zaon connect to the 12v bus use some type of EMI filter? Thanks. B
