New Stryker 497hpc interfering with my omnitracs eld GPS

I know when I have my gps too close to my HP40 and key up it will make the gps go haywire.

 

You tried swapping the CB with another one ?

 

I doubt he has. After spending a few hundred dollars on a nice radio, he probably wouldn't want to either. If he hasn't done it already, I would recommend that he turns the power down to its lowest setting. I would think that would be easier than swapping radios, and it would give him the same results. Then key the Mic and watch the truck lites and GPS. I think it's just putting out too much RF for the trucks electronic system. But I could be wrong. Plus with these newer trucks, bonding is the first step to make the antenna system work properly.

 

I am sticking to what I said, this sounds like a Leakey coax or common mode current. the cutting of the coax without confirming the multiplexer is in place and just the leakage in the radio could be the only issue ==== but what do I know??

 

Yes sir, I agree. It's definitely a CMC issue.

Edit: I need to correct my first post. It looks like the 90 - 100 watts peak power is in FM mode. This radio doesn't have SSB, my mistake.

 

I'm thinking about trading my 497hpc to a radio with less wattage and see if it fixes the problem. I would probably try it out first before trading it in. Or i can just replace my eld to motive. I'll keep you guys updated.

 

So i went to a different cb shop and let them run a direct wire to the battery and they put the coax cable to where it was from a T split to now a single coax with dual cables. But the problem is still there gps on my eld still losing signal. downgrading my radio to a less wattage or replacing my eld are my next option. I'll keep yall posted.

 

Okay tnx for the update. I don't think you need to down grade radios, unless you want to. Your radio has an RF power knob. Since you were just at a cb shop, that would have been the perfect time to test it. The tech could have put a power meter in line and with the Mic keyed, lower the power on the radio down to its lowest reading. If you lower the power down to 4 watts (the radio should go that low), and it's still interfering with the ELD, than a different radio won't help. Unless your new radio has a loud and proud tune (basically a splatter box), than that would be a different story.

 

OK this happens when your radio is TURNED ON, Right?

What model of Omniracs do you have? MCP110?

 

Yes, the radio is on when you turn it off everything's fine. The unit is omnitracs IVG
