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.

    • Definitely plan on doing some pulling by hand ealry ice so I'm thinking the cabin it is then. Thanks for the tips and info on the otters and equipment it's been a very big help!
    • Yep, I've contacted 4 or 5 campgrounds in the last couple of days. One has gotten back to me, the rest have not yet.   We will be up that way over the Labor Day holiday so we can check out a few campgrounds while we are there. We actually checked out 2 or 3 while we were up there last year at that time.   I'm not too sure if we are ready to take the plunge yet or not but we are close.
    •   If you are start talking to the owners of the campgrounds now about letting you know when there may be an opening. Ours fills up during the summer but at the end of the season the owners will start hearing about those that will be moving out at the end of the year. Lot's of relatives will tell their families as soon as they hear someone is moving out. Good Luck.
    • Thanks guys. Looks like there are a few lakes to checkout.
    • I really hope the wolves aren't seriously considering this. You take LeBron James off the cavs, and Irving leads them to an 8 seed in the east, at best! This is going to be KAT's team for years to come, so if Irving is looking to be top dog, it certainly won't be here! Personally, I don't think he'll be traded. If the lakers show any sign of improvement in this upcoming season, LeBron will be leaving to go there anyway, so Irving just needs to be patient and he'll be he top guy again.
    • We're definitely checking out our options in a couple of areas we like but I'm not sure if it will happen as early as next year or not.
    • Definitely something to be said about parking it an leaving.  My fees are nothing except the bills I help pay for at the family cabin.  Would hate hooking and unhooking all the time.
    • Still have my old sno-boat. Best portable shelter out there for pulling by hand. You scored a heck of a deal! I feel mine is irreplaceable! I don't use it much, but when I do, I'm so glad I have taken care of it and still have it 16 years later. I've had 1 zipper replaced on the D-door and some patching done at Canvas Craft years ago.  I think the other zipper is on it's way out, and will definitely get that repaired when needed. 
    • If you planning on doing any hand pulling at all then do not get the lodge she is a tank and would not fit in a short box. As long as your not 300+ lbs you'll be perfectly comfortable with 2 adults in the cabin. Also a cheap alternative to Hifax are a set of old downhill skis (normally $7-15 @ goodwill) I pull mine across parking lots all the time behind the wheeler and they hold up really well. An added bonus is if you cut them off at the end of the sled then they work great for loading and unloading the shack from your pickup box by yourself because the steel sides dig into the ground a bit keeping the bottom from sliding out.
    • tip to a couple good friends   Len,
      Thank you for the stream recommendation, Len! I love the layout of this stream. Fished it from 3pm until 6:30pm.  My brother threw panther 9s and I threw 6s. We scored a brookie/brown/bow trifecta.
