Thread: Rf Interferance

I seperated the trolling motor cables away from the transducer cables.

Here's the latest update. Now I'm more confused than I was before. Humminbird sent me a tmc1 choke and two ferrite rings. Installed the tmc1 and it made the rf interference worst. Now I'm down to buying a new trolling motor and replacing the transducer. I can set the sensivity on 9 or below and not have any interference. If I go higher it gets worst. Right now it's useable. I'm going to take it down to Ranger this summer and get a couple of cosmetic things done to it. I'm probably going to have them move all of my Tm batteries to one side. I also found some 14-2 twisted and aluminum shielded wire. I already ran new wire straight to the battery already but it's not aluminum shielded. I hope I can get this lined out. I love the 1199's and the 360. My buddy has 2 1198's and a 360 it's a deadly fishing system. So getting Lowrance electronics is out of the question for me!

You've already determined the RFI is getting into the xducer or its cable ...

There is 20' of xducer cable ...

Somewhere along that 20' ... The RFI is encroaching ...

Use the same scenario of removing the xducer and its cable away from the TM to where the RFI goes away ...

Then start experimenting with that entire 20' until the point of RFI encroachment can be determined ...

I'm guessing you have a small nick in the xducer cable somewhere ...

I will have to check in to it. This Rf issue can drive a sane person crazy.

it's definantly a process of elimination. A giant puzzle!

Can it drive a crazy person sane.....If so, I'll have to introduce some on mine.

I found this video on you tube with a bow mount transducer bracket. I've been thinking for better and more accurate SI and DI this would work better any way than having it mounted permanently to the Trolling motor. https://m.youtube.com/watch?v=4sI6gd4RMz0
