Wandersound Stereo Interference - jwasnewski - 05-19-2007 08:46 I recently completed the installation of new rear and side cameras. They work well even at night. I used the same on/off switch and constant voltage power supply as the old camera system. All wiring after the power supply is new 20 gauge wire fused with 2amp fast blow CMA(??) type from Radio Shack as per instuctions.. I installed two 3.5 LCD monitors using the same video cable as the old camera on the rear camera. I used the cable that came with the side camera, 4 conductor S Video. I noticed this morning that my Wandersound stereo signal gets knocked off line with ensuing static when I turn on the cameras. Any frequency guru's out there? Any ideas? The TV's are not affected. No interference before the retrofit. I did not see any capacitors???in the power lines of the old system.

AM radio sound is virtually impossible with all the competing rf and line interference around the coach. Now if you were having interference on your FM signal or a CD, that's probably fixable but not by me.Brad Barton 00LXiDFW bbartonwx@...

Wandersound is above the FM stereo and equalizer. The FM stereo is Kenwood KRC555 with graphic equalizer Kenwood KGC 9400 with LED monitor bars for all the various Hz bass, mid-range and treble controls. I imagine the original units. I figured out a few minutes ago what is happening. When I turn the cameras on it knocks 98% of the Hz bars down to zero, one dot. No music. It does not turn the equalizer off. Weird. Tanks for the response. Leroy Eckert 1990 WB-40 "Smoke N Mirrors" Niceville, Fl > > > Leroy, > I'm not familiar with Wandersound, but I remember my 84 was just like my 00.

It is working perfectly now. This computer must be passing Gamma Rays through me or something. I am way in the boonies, have a strong FM signal and haven't had a cocktail either. Leroy Eckert 1990 WB-40"Smoke N Mirrors" Niceville, FL Communicating off someone's linksys????very low signal Wandersound Stereo Interference - Richard Hayden - 05-19-2007 16:01 Leroy, Perhaps you might have disconnected the antenna lead-in for the radio when you were working on the cctv. If that is the case, it will happen again. Mine was loose and was intermittent till I found the reason. Mine wasn't on the radio but on the equalizer connection.

Matter-of-fact not a guru of anything. 1.) You know for certain that the WS is affected by turning on the cameras. How about turning on the other way, first the cameras then the WS, Problem persists-No problem? 2.)For best results signal wires should cross (+) at a 90º, not laid along side one another. Also, the grounds around the two conductors are beneficial when there is a good ground. Use an ohmmeter, on the lowest scale X1, check resistance on the shell of the S-Video plug to a GOOD, NO! GREAT ground. (Fabulous will work ~(;>)) 3.)With WS on, disconnect one camera S-Video at the camera, turn camera on and off several times to see if WS is affected. If not, replace S-Video on this camera, repeat the process on the other. One or the other may be the cause, just narrowing down the source. 4.)The problem may in fact not be related to the S-Video but to a momentary drop in supply voltage as the camera is turned on.( Usually spikes are caused by the inductive kick of a coil radiating and induced into an adjoining conductor, I don't know of but perhaps there is such a coil in the system?) A voltage drop may not be seen on a meter. You would have better results getting the supply voltage (12V) from another location temporarily to see if the problem persisted. A capacitor across the source may prevent the disruption. 5.Check the voltage source wires of the WS, see if they can, or other wires of that system be moved slightly away from the vicinity of the camera system. 6.)Call the supplier asking if they have heard of their system affecting other sensitive systems in motorhomes. S-Video is nothing more than (2) twisted pairs of wires commonly used for brightness and color.Each signal wire is twisted with a ground wire and includes a sparsely wrapped ground foil on the outside. A better S-Video cable may end the problem if in that area, this one with better shielding and plugs for example. http://www.bluejeanscable.com/store/svideo/index.htm Bob Janes, Greenville --- In WanderlodgeForum@yahoogroups.com, "jwasnewski" > > I recently completed the installation of new rear and side cameras. > They work well even at night.

I drove 6 hours today listening to various FM stations and all worked well. There is a mass of wires in the area so perhaps I need to check the connections. I may have moved them around.Thanks for the suggestion.

Here is why, perhaps. I could not find a pre-made harness at Radio Shack which went from S Video to a standard push in video connector like plugs into the back of a TV. (yellow connector) I wired about 2 feet of harness using 20 gauge wires, ground, video and power to complete the installation. These wires are wound together without shielding. I'm now wondering if the power wire is affecting the video signal? I'll check it out this weekend. The problem occurred in the 92.4----92.7 FM range. I didn't write it down at the time simply because I don't know what I am doing on these things until after the fact. lol Thanks for the input.
