200 kHz

Recommended Posts

If you have a sounder running 200 kHz and FL-8 running 200 kHz in the same boat, can you hook them to different batteries so they will not dislike each other?

Any help would be great...

PS. Does anybody have any experience with Garmin GPS/Sounders?

Dman I have to respectfully disagree. I run souders with the same frequency with little or no interferance. Vexilars seem to interfere no matter what frequency sounder your using. This is the only reason I bought a Vexilar. I personaly think there junk. My video's and LCR's out perform the Vexilars by a wide margin. But when your in a shack and people crowd you with a Vexilar you either buy on or fish blind. I think Vexilar is well aware of this interferance and use it as a marketing ploy. I cant tell you how much distaste I have for Vexilars. I had to get that off my chest. Good Luck, ST.

When i run my Lms-350 and x-85 at the same time, the screens on both are distorted. They both run at 192hkz. Can i ask what models and what frequencies you run at the same time with no interference?

Yes Lowrance's at 190khz have that problem. with each other. Hes an example of what I have found. Interphase and say Coden at 200khz are happy with other in any combo. Now say you threw a Hbird,egale, or lowrance in with the mix and all is good. Now mix a Vexilar with any of these and you will get interferance. All findings would be with gain set to double echo just to keep a constent comparison. It would be nice if I documented all these findings over the years to have a compatibility list. But I didnt.

This is one of those "laws of physics" that you'll just have to make the best of. Since all sonars use the same principle of pinging a transducer at a set frequency and listening for an echo to greate an electrical pulse back to the amplifier, they will inescapably pick up each others signals. The input circuit will filter out the received signal based on a bandpass filter centered around the pinged frequency. If you have two sonars operating at 192KHz they will pick up each other's signals. On a Vexilar you will see this as a light rotating around the display. The speed of the rotation is proportional to the difference in their actual operating frequencies.

Since the bandpass filter in different brands of sonars will be slightly different, the degree of interference will vary between combinations of sonars, signal power, transducer mounting angle, and other variables. The best way to deal with this problem is simply to adjust the gain of the amplifier by adding supression until the offending signal is minimized or eliminated.

To completely eliminate interference you could design your own sonar that used a programmable, digitally encrypted pulse train type signal like the type used on a garage door transmitter. Wouldn't that be cool?

    • So reviving a dead thread ..


      The "park switch" may be the cause of the parasitic draw on some of the console equipped models, 
      it's an inexpensive switch that sends a shutdown signal to the BCM. When it goes bad the dash lights do not shut off and it drains the battery. 
      Fords fix is to replace the whole shifter assembly at around $650.00, they do not sell just the switch. 
      Here is the replacement switch with an more detailed explanation of why it happens.

    • I leave it behind on purpose at times..........
    • NOT in some of the places i go fishing.................AND most the time i go fishing to get away from said phone!!!!!!!
    • Sounds like a good seminar!
    • After starting out the winter with a lack of snow February is making up for it. Earlier in the week the southern half of the state received 4 to 6 inches of snow and in the last couple of days the north and northwest received from 4 to 8 inches of snow.Snowmobile trails are now open in most, but not all, counties across the state with conditions rated as good or excellent in many counties on the Wisconsin Department of Tourism's Snow Conditions Report (exit DNR). Many state properties were regrooming cross-country ski trails and ski trail conditions ranged from good to excellent. Some freezing rain fell in the south after the snow, resulting in some icy conditions in some locations. Temperatures are expected to warm this weekend, especially in the south where more rain is also in the forecast, while the north is expected to get more snow.With all the recent snow, conditions should be excellent for the American Birkebeiner Ski Race this weekend in the Hayward-Cable area. It is the largest ski race in North America and attracts thousands of skiers from all over the country and world -- skiers from 49 states and 36 countries participated in 2018 -- and draws tens of thousands of spectators to the area. .
    • I doubt it but you can call the DNR and ask. You can pull up the regs on a smart phone anyway.
    • ......The 6 packages from the first round are long-gone, so I am brining up another batch. Ended up buying an entire case of butts (@ $1.18 per #) from Sams. I am going to do 3 butts - one with High Mtn buckboard seasoning and two with another dry brine consisting of Tenderquick, brown sugar, garlic salt, and black pepper. I always like getting to the raw ingredients of spices versus relying on someones "magic rub". If it goes badly I will revert back to the HM cure. As an added note, I also picked up a $20 loin that I put HM cure on to experiment with some Canadian bacon.... Will check back in 10 days or so!  
    • if thats the case i hope there printing water proof versions!!!!!!!!!!!!!! i cant keep mine nice and tidy in the cab of my truck!!!!!!!
    • Have not heard this. Why just a boat? It needs to be in some peoples buckets to so when their 500 fish over their limit they can't say I no know, I no know? 🤷‍♂️
