Thanks to everyones help on here, I have a quiet and clear intercom and all my new radio/GPS units work well together.
I DO have some other issues.
ISSUE#1
I spaced (height) my Garmin SL-30 and Garmin 430W even a bit further apart than the manual calls for when I mounted them in the panel. I wanted good air circulation around them. I have a new cooling fan connected to the 430. I verified excellent airflow into the 430W tray.
BUT the sides of the faceplates on Both the SL30 and 430W are very hot to the touch when they have been on for about an hour. Is this normal?
Would running another cooling hose (I can have up to 4) from the avionics fan to the SL30 help any? Any ideas?
ISSUE#2
I have a panel light dimmer that is from an older aircraft.
It is the style that has two knobs (inner and outer).
I elected to let the entire radio stack use their internal
optical dimmers. They are NOT connected to this dimmer knob.
The only items connected to this dimmer are a
gooseneck panel light with a incandescent red bulb, a LED lighting strip, both the Garmin OBS indicators, and the light up buttons on the autopilot.
The knob and dimmer assembly are hot to the touch after an hour of flying. I feel I do not have much of a load on the circuit so I wonder why this is?
ISSUE#3
My other issue are the comm radios.
They have the exact same length individual antenna cables, and each has their own identical new antenna. I am able to pick up AWOS and Tower from much further away on the 430W than the SL30. I am thinking the menu controlled sqwuelch on the SL30 needs to be setup? The 430 radio just seems to be 20% better performing all around. Any ideas??
