I just put on a handheld Midland cb and have been told I have a little squeal when I transmit. Where and how does a filter go on to stop this and where can I get one for this radio for my trike ??

do you have a regular antenna or handheld
most likely the SWR is bad did you set the tune on the antenna

Check to make sure that all your plugs are matching up properly. If there's a mismatch, you could transmit a squeal. Usually a squeal like that means some sort of feedback problem, possibly due to a short across plug contacts in the headset cord plugs or the one that plugs into the helmet. If that doesn't work, give Sierra Electronics a call. They're pretty good at trouble shooting that sort of stuff.

FireEater,
It will help some if you try to isolate the source of the squeal. Remove the CB from the trike and any external wiring and see if you still have the noise; if so it's in the CB not the bike.

If no squeal, start connecting the CB back to the bike (not running) check for the squeal. If no squeal, crank the bike check again for the squeal. If no squeal then try with bike at highway speeds.

If I had to guess, I would suspect that some of your wiring (headset/power) is picking up alternator noise. If you are hardwired for power, an old CBer's solution was to run a shielded cable (antenna type cable) direct to the battery; battery served as a filter.

Good Luck!

I have used the Midland handheld on my other bike and found if the power switch was in the high power position the transmit would squeal. When I ran it on low power I had no problem at all. Range was short, but the batteries lasted longer and no noise. When hooked into the bike electrical system, I always picked up alternator noise until I used a ground loop isolator on the speaker output that went into my headset.

Can you provide some directions regarding the ground loop isolator for the handheld cb?

Thanks for all the advice. I am going to try this one first...and see what it gets me.

I use the Ground Loop Isolator that would plug in-line with the speaker of the headset to remove the electrical whine. The one I use is from Electrical Connection. Also great if you use an MP3 player that charges from the bike. My Lowrance GPS that has 4 Gig of MP3's would always whine when I used my helmet setup. Plugged the isolator in-line and all that whine is gone. :lol:

I do not hear a whine when listening, I send out a whine when talking I am told.

I have not had a chance to try a few items listed above, but will and will report back the results....:thumbup:

Bump!

Hey FireEater,

I bought a Midland CB after seeing yours at the Coney Island lunch. I also have a loud squeal when I key the mike. Rose and I both use Kennedy FRSet4's and patch cables that allow keying the radio through the OEM CB switch (no OEM CB installed).

When either of us key the radio, there is a loud "Thunk" sound from the bike's speakers even with the radio turned all the way off. The radios are on low power. It sounds like feedback of some sort making it's way back into the audio system.

This system works perfectly bike to bike using our FRS radios. I wanted to try CB for when we ride with other Wing riders. I've just about given up on CB at this point... :-(

Do you have the same problem with the engine not running? If you don't, and the problem is only with the engine running, then you know you need some kind of filter and/or loop isolator.
