      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Trolling motor and AM radio

Recommended Posts

When I fish late I like to listen to the Twins while I chase the elusive exclusive Muskellion. But every time my foot hits that pedal I get a high pitched wheezing sound out of my radio speakers. I don't think that it happens when it plays a cd or fm. Is there anything I can do to block this interference? Its getting pretty annoying and I'm talking about more than Bert Blyleven's commentary.

Thanks!

I have the same exact problem. I put up with it for 4 hours on opener while listening to the Wild in the playoffs, but man is that annoying. Now I only turn on the Twins when I am anchored. Anybody know a solution?

Sounds like you need an RF filter.

The only other solution would be to get a portable radio that runs off alkaline batteries.

Go Twins! Go!

If you are running a marine or automotive type head unit for a radio, there are interferance filters that plug in-line to the antenna cord (check radio shack). If the electrical systems are isolated, there shouldn't be any noise comming through the power system, then more than likely it is simple electro-mag interferance generated by the motor at the same frequency as the radio signal, or being inducted into the power cables, and there is not much you can do except tune into a different frequency or put up with it, short of sheilding the electrical systems, or perhaps an antenna booster?

The best thing to do is to try and segregate the electrical systems the best you can. If possible try to place the batteries on opposite sides of the transom and run the wiring for the trolling motor on the opposite side of the boat that the radio and it's electrical is run(i.e. make sure the trolling motor wires do not come close to the radio and its supply cables). Make sure you tuck all the wires under the boat metal. RF fields are line of sight types of induced current. If you obstruct the line of sight with grounded shielding this eliminates much of the RF fields induced current. Trolling motors do not produce high RF fields therefore it sounds to me like some of the cabling are too close together or the batteries may be to close together. RF currents can back feed down the cable and cause havoc with many instruments. As stated before their are RF filters on the market that can be used but I would make sure you obstruct the line of sight and segregate cabling as much as possible. The fact that you are picking this up on AM frequencies and not FM is due to the frequency of the current being induced onto the ground or +12V power line of the radio. Also make sure the antenna is not close to the trolling motor wiring and make sure the trolling motor cables and wiring are NOT coiled. Coils produce greater EMF's and RF fields. Coiling wires produces an antenna for transmitting undesireable RF fields.
Hope this helps you out some.

is the radio and trolling motor running off the same battery? if so, then the motor is creating the interference you hear. If you can get a separate smaller battery for the radio, it would eliminate it.

Comments from others?

coldone hit it on the head. On the AM side of things you will get noise especially with a magnetic field caused by an electric motor running. AM is suseptable to all types of interference. Take a portable radio and move as far from the source of the noise as possible (while remaining on the boat of course)

    • I will decide if that is true when I get my nills back out. hopefully soon. 
    • Would you be able to post pics of your bed again?  I really like that idea, very smart.  Would you make any changes on the next one.  Should get my firebrand shell this week, lots to do.
    • Beaver Bay sports rents although I've never used them. 
    • There's really no wrong way of doing a roast if ya ask me, it's all personal preference. Crockpot,  roaster, oven or boiled (del) . Although I do enjoy throwing cold smoke this time of year at a roast before it hits the roaster!!
    • 2nd that,  30 years here...
    • oh wow!!!!!  poster too!!
    • Yer gonna be blowin' chunks one of these days, Delbert. Why not just an easy overnight marinade, then in the crackpot on low, and lift that lid a few times to keep the heat low? I always pull mine at 4-5 hours on LOW, not the 6-8 they say. I have about 155* internal and still pinkish at that, and I have 3 different crackpots I use. Never had it fail in oh, ten or fifteen years.....maybe because I always do a top round or rump, instead of an arm or chuck. You DO  occasionally get a tougher one, that has a lot of sinew in it, that's why I eyeball mine so carefully. (working 2 yrs at the butcher shop helped, too) I always let it sit in a covered glass dish for 10-15 mns before I start slicing away....
    • I worked with stainless for 28 years, it's the way to go.
    • Yeah, I forgot to include the LEM, which is basically the Rikon with a different badge. I know that style will cut better and definitely be a better unit. Just not sure if I am going to justify the price at 2x higher for a very occasional piece of equipment.    A wood bandsaw could be used. The saw doesn't know whether it's cutting meat or wood. The difference is that a stainless table and blades would be preferred IMO. Cleanup probably isn't much different between all of them.
