Thread: U S - 2 terrova rf interference (long winded but may be worth the time)

Ok guys I do understand that the probable source of the rf is the trolling motor . I guess I should have said the rf is coming THRU my transducer and its cable instead of saying it was coming FROM the transducer and its cable. I simply resolved the problem by using an external transducer instead of the internal US-2 , I did this because after a couple of calls to HB support the problem was still there , I was not offered a free noise kit , it was never mentioned and was told to be sure the transducer cable was not routed close to the power cable , but they did exactly that when they designed and built this product.they did send me a pc-11 power cord after I requested it . It did not help.My opinion is that when you manufacture a trolling motor that is a known source of rf and offer it with a built in transducer your begging for rf to end up at the customers depth finder. if the noise kit is free they should put one in the box with each motor they sell.Maybe I got ahold of a couple inexperienced tech support people when I called for help, I've learned more from this thread than I did from them. I realize i could keep working on it and maybe get it to work properly,I'm happy with the terrova and my 2 HB depthfinders but for me the US-2 option was not worth the trouble. Thanks for your help and input I do appreciate it !

x-2 shouldnt even be an option us-2 sux

One note, when I upgraded to the ipilot link on the terrova a ferrite ring came with it to install inside the base of the TM . I had some rf problems when I had a motor guide and went through all the tail chasing. It all works perfectly now. I know it is frustrating but stay after it.

I've got a new Terrova with US2 and a 788 up front....no interference at all...I mean NONE. I think this is the first TM/ FF combo I've had that didn't have at least a little receiver desensitivity on it. My trolling motor does not share power with anything else though.

I have a new US2 Fortrex and the interference is bad (Lowrance HDS), a lot worse than the Maxxum it replaced. I have the choke, ferrite cores and finally made some adjustments to the df to make it tolerable. If I had room on the tm for a 2d transducer I'd put one on it, but the LSS-1 transducer takes up pretty much all the space on the motor. I called minn kota and they were no help. Their customer service is not very impressive IMO.

My US2 works just fine.

I have the same problem. Where did you disconnect the US-2 transducer? In the TM head.
Thanks
