Interference on AM radio from Sonar/GPS??

6 posts in this topic

I would like to listen to the Twins but have so much interference from my eletronics I have to turn off my GPS. You guys have any ideas?

My first idea is that it'd probably be a lot better if the Twins were still on WCCO (better signal).

What you're getting is electrical interference ---- try moving your am antenna away from your gps and see if that does it ---- try moving the power wires for the radio away from the power wires for the gps and see if that does it. A lot of times moving them an inch or two will make all the difference in the world. Good luck getting it figured out.

I was out in a buddy's boat yesterday and we couldn't get the game on his radio if his bowmount was running or if the boat was turned in the wrong direction --- but I don't think he had much of an am antenna.

I'm with you too on this one. I get interference from my Eagle 640C in the boat, in the winter,(late ice, sunny day, listening to a spring training game is very nice in my book) it comes from my LX-5.

I have to shut off the sonar if I want to hear the game clearly. I fish at Mille Lacs occasionally and can pick up the Twins on an FM station out of Brainerd. That comes through nice and clear. Check you area, perhaps an FM station is close enough. The antenna of my boat is inches from the sonar unit. Not much I can change about that. I hope I locate some fish before the game gets to interesting. On a nice weather day, fishing with the game on,,,,,,,,,,very nice! Makes me glad I do this.

Try putting a sheet of aluminum foil between the antennas if you can't move them. One day out on the water with an old radio it was picking up interference from the trolling motor, so when speeding up the frequency would increase of the noise, and slowing down it was like the cartoon falling bomb sound effect. We changed to a wire loop antenna radio and fixed the problem.

You can add a ground interference insulator to the radios line, that will cure it. Most stereo stores will have them or drop in at Radio Shack.

I just noticed this while using my H20 in my truck. When I unplugged the external H20 power plug from the truck's power oulet, the interference noice on the radio stopped. So, I assumed corectly that it's a power interference issue. I don't use it often enough to worry about it, however.

    • that would be samanthasquatch 
    • It's a female Bigfoot,  silly.
    • You can save the mapping data on an SD card. In order to create a map you will need the Zero Line Card. You will take the SD card and plug it into your PC. Down load the map data into the zero line software. The software than creates the map and uploads it to the zero line card. It is typically recommended to use an SD card for the data as once the zero line card is full of either maps or map data another card will need to be purchased.
    • whats a samsquatch?  lol
    • Nope....don't need friendseyeguy54..... It was a darn samsquatch!
    • Way to get him out MM!  I'm sure he appreciates it.
    • I believe some units come with maps of some lakes but probably wont have any real detail as far as contour lines.  I think most will have a map of the US but when you zoom in you wont get much for detail on lakes and If they do contours will probably be 5-7ft apart.  If you want to put data on a card you will need a zero line card for mapping. About $150 i think.  8 hours should give you quite a bit of mapping.  Best would be to buy from a retailer so someone with knowledge of the product can show you how to run it.  You might be able to take some snap shots of sonar and put on a blank card but don't think you can map with it. I would get a Lakemaster card for the area(s) you want to fish.  Worth every penny.
    • Turkey season is over for my nephew!! It was a long season with many hours spent in the blind. He seen more turkeys then ever before and had a toms close enough to grab. It is going to be nice to sleep in. Until fall turkeys!
    • Heading up to Devils in a couple weeks and again later on.  Doesn't look like a lot of activity on here.  Tryng to get an idea whats happening before I go.
    • I have been out the last two days locally and haven't set the world on fire. Caught a few each day, but fish have been scattered. Lake is loaded with curly leaf mats this year, so that hasn't helped things. Once that starts dying and weather warms up, things should pick up.
