Question about Midland 1001Z 40-Channels Base CB Radio
I receive signals very crisp and clear on all channels. However when I key the mic, whoever is receiving my signal, hears a very loud mono tone squeal. None of the controls have any affect on the noise, yet when I move the mic around in the cabin, the squeal changes tone. Also when I wrap my hand around the mic cord at the top where the coils begin, the squeal goes away, the digital power meter goes into the red, and I transmit just fine. I am using: New Midland 1001Z radio, original stock mic that came with the unit, 3 ft adjustable Firestik antenna and a Hood Channel Mount kit that includes 18 feet of Fire-Flex coaxial cable with the Fire-Ring connector.
I have the power connected to the fuse block under the hood and ran through the firewall using the supplied rubber grommet. I kept the ground wire short and found a nice ground near the steering arm. I have heard that shortening the coax cable affects the whole system so I kept it at the stock length. However since I am short on room, the excess slack is coiled up and stored behind a dash panel.
My guess for my problem is either the coiled up coax, the coax running along the hood channel, or bad grounding.
If it is a bad ground, how would I check for a solid ground? Also the antenna and mounting kit does not mention anything about grounding the antenna, do I need to do that with my set up? (See picture above) If so, how? Thanks for your help!
Comment by Rouge 2, posted on Mar 15, 2008 I have deduced it is not the coiled up excess coax because I stretched it out and still no change. The noise goes away if the antenna or coax cable is gripped by a human while the mic is keyed. Hopefully this helps narrow down my problem for someone.
Try changing you mic and also keep it away from your external speaker if you have one. There are ways to cure this symptom and they are inexpensive and you can do it.

Grounding the antenna bracket is extremely important, if it's bolted into the metal frame or fender it should be OK. The coiled coax cable could be the culprit but that's only a remote possibility.Try running a separate groung wire from the radio mounting bracket (or one of the radio's cover screws if not using a bracket) to the CLOSEST vehicle ground...keep this a short as possible. Your problem is definitely caused by insufficient ground at either end of the coax, with the antenna side being more suspect.

Hi yes it is possible as is anything if your willing to pay for the conversion , it would require new chrystals and resetting of the If system but is possible . However porobably not economical Midland did do The 100 model in an Fm modulation format and you will probably find still available on Ebay or Amazon if not that paticular one a good version at any rate ..I beleive they did actually do an Am Fm model also ...Regards Vortash

soundwas keying up at the same time.s like it could be one of two problems. a loose wire in the mic or some one near you keyed up the same time as you. if the wire in the mic is loose sodder it. If some one keyed up near you you might have blown the reciever chip.
