compass problem... - Striper Talk Striped Bass Fishing, Surfcasting, Boating

My radio is causing too much compass devation for me to compensate for. (I think it is the magnet in the speaker) Moving it lessens it somewhat but not enough. Anywhere on the console is pretty bad. Also, moving it would be to a place that is not as nice as it is now and would be a pain to do (A weekend job involving milling a new starboard piece, and hacking a rather large hole in the console and all this for not much improvement.)

Is there any way to physically shield a radio from the compass?

been surfing the net for a solution...looks like there is none.

Hmmmm. looks like I have another project this summer. I could buy a T-top, install an electronics box, and put the radio in there and re-do the dash. (jezzz, it would be easier to buy a new freeekin boat)

I might play with some magnets and if it looks possible to correct this, if it does, I will call in a compass guy to do it. I would like to have zero deviation but right now I have 30 deg.

(this is why I have 3 gps's on board, my compass is worthless as it is now)

Jim you sure you don't have a compass problem? Electronics can add deviation depending on where they are, but how much you talking about? Is it having problems with accuracy in some directions?

Sorry I just re-read that and saw 30 deg...I would have the compass changed first...unless moving the radio away by hand is causing the compass to move too?

keep the radio in the same place and just relocate the speaker?

Salty, I remove the radio from the CC and the compass is within a degree of my hand bearing sighting compass. Put it in the dash and it move 30 deg. My GPS is with inches of the compass and has little to no effect on it. I pulled the radio out, and moved it all around the console to find a better spot...it is going to be tough to find a sweet spot...for the heck of it, I put it next to the compass and it set it spinning like a top.

Raven, while in the shower this evening, I thought the same thing

..what about an external speaker? I am headed over to the ICOM site now to see if something like that is available.

thanks
