UHF Wiring

[303ChickenMan]

Hey guys!

Preface: I’m not great with electrical but am an ambitious DIY guy. I don’t want to burn down my Gren or cause issues for this project.

I have a Midland MXT575. It fits PERFECTLY behind the plastic panel in the footwell right where the Int2 switch is wired. I love the idea of having it wired into that outlet considering it’s in front of an ignition relay with the option to turn it on overhead. However, I’m concerned about the power requirements of this unit. It peaks at 10A and 13.8v. Midland says to run 10 gauge wires beyond 10 feet.

Wiring into this outlet — “go” or “no-go?” Otherwise I will resort to wiring directly to the battery or a fuse box.

I wired my UHF to the Int 1 wires in the footwell. It is a RHD QM. No issues with power draw, and even wired a USB outlet to the same wires. Int ! and Int2 are both fused, so will blow a fuse if too much current draw.

When I first read your post I thought 10 amps was a typo but no, you guys have 50 watt licenced radios that pull a lot of supply power. Australian unlicensed UHFs are 5 watts and fused at 2-3 amps. You're probably ok to run from INT2. The radio can pull 10amps but only under maximum operating conditions. Buy a spare fuse.

I’ve thought for a while now that Aus needs to up our game and move up from 5 watts. But like the fast train between Sydney and Melbourne, I unfortunately can’t see it happening in my lifetime.

I have it running on INT2

I am installing the ICOM 2730E and this model draws around 13 amps, while transmitting, and 1.2 amps in STBY. I am installing it to the AUX Bus, although I am afraid it draws power even if it’s not powered on or I forget to power it off. How are you guys wiring it? Or just to remember to turn it off?
