Hello All
I’ve been in the process of installing ‘’a new to me ‘’ GNS-480 as a second COM with an SL-30 and a Dynon Intercom and due to space constrain I was planning to use a switch to select either Com# 1 or Com # 2..
But last night, I read again the installation of my Dynon Intercom and it says that to do so I will need radios with built-in Transmit Interlock.. The problem if I’m right is that the GNS-480 & the SL-30 don’t have Built-In Transmit Interlock ( as per Garmin Support ) but rather a De-Sensor of some kind that reduce one radio’s power when the other one is transmitting....
I’m curious to know because right now when both radios are ‘’ON’’ I get a scratchy noise and when transmitting with the SL-30, the GNS-480 is also transmitting.. When transmitting with the GNS-480, the SL-30 does not transmit..
When either radio is ‘’OFF’’ , the other one is working normally..
The wiring harness is OK as far as I know ( I will check it again ) so maybe I have a faulty Intercom ??
Do you guys know if there is such a thing as a Transmit Interlock that can be added to the intercom to make this thing works..
Any inputs you may have will be welcome as I’m running out of ideas..
Thanks
