Gulf Coast Avionics GCA-24 Portable Intercom

I purchased this intercom for my 46 Aeronca Champ. Operationally it does the job very well. Battery life is quite long. Considering that I only use it for a couple of hours per week, battery life is measured in months. Audio is clear, and operation of controls is straighforward. The only reason I have not given it 5 stars is its lack of mounting arrangement. It would benefit from a dedicated bracket for mounting on either the side wall or the panel. I was able to make a mount from a modified plastic container that works well for the forward left side wall.

I am glad I bought this! I don’t have and airplane but I use this intercom for an off road vehicle, and it works great. I am happy with my purchase

Good

Amazing clarity and great battery backup which last a long time
