Question about Midland 1001Z 40-Channels Base CB Radio

1 Answer

Horrible Noise I have recently developed a horrible screeching in my radio. It is not affected by the volume of the unit, and is only heard if the radio recieves another broadcast or if the squelch is turned up. The unit is only 5-6 months old. I know nothing about cb's, so I don't even know where to start troubleshooting. Any suggestions??? Thanks

It may be a cold solder joint on one of the stand up boards. Check all your connections and solder any bad joints.

My Ranger2950 has no sound??

Have a look here for info about the Ranger 2950. This is an Amateur 10 & 12 meter transceiver that enjoy some popularity due to its ability to be modified to work on the 27Mhz Citizens Band.

Make sure the Mode is set to something other than PA. A few of the first things that come to mind is the Volume, Squelch & RF Gain settings. The Volume is straight forward - choose a setting in the middle to begin. Next, set the squelch. Most radios have the squelch open when set fully counter-clockwise. As you move the squelch to this position, sound should be heard from the speaker if a signal is present. As long as there is an antenna connected, the radio should "hear" noise. If you do not hear anything, leave the Squelch fully CCW and try varying the RF Gain fully in one direction. If you still hear nothing, set the Squelch to the fully clock-wise position. Adjust the RF Gain to the opposite direction. At this point, you should have heard something - even if just static hash. If not, the volume control may be dirty. Disconnect power and rotate the volume control back and forth several times to dislodge any dirt on the volume wiper inside the radio, and try again.

Make sure that the Ext Spk jack does not have a plug inserted as it will defeat the internal speaker. Likewise, if using an external speaker, make sure it works.

Good luck!

Uniden uh015sx won't receive or scan

FM Detector/demodulation issue. These radios have a problem in this department. I have had a few come through work that were on mine sites and no longer receive or scan. On the display it will show the signal bars fully lit as if there is a strong signal, but no RF is heard. The giveaway is being able to hear button press beeps and alike but no signal noise is ever heard.

If the unit is still under warranty send it back and have it repaired. If no longer under warranty, then it's spare parts.

Magnum 257 HP , no problem at all on AM or FM , modulation OK. SSB is distorted with low modulation , higher modulation seems to make it better but not consistantly . Used dummy load , BK CB tester w/2...

Nope, your not the only one. Poor power regulation internally and maybe check your antenna swr. Higher wattage with even 1.9:1 i have seen exports have issues.. and then the magnum with there alc mod (compressor) on the op amp..

I bought this from a buddy of mine then my other buddy hooked it up for me and the sound isn't workin and I think the speaker is broke or whatever you know. Are the speakers sensitive?

First, this is the worst radio Cobra ever made. I don't know why they still make it. Its horrible.

You probably have got a bad mic, or a break in a wire in the mic cord. With out a properly functioning mic, the radio will not go into receive mode. Thus you will have no sound.

I wouldn't waste money on a new mic for that radio. Instead save a little more money and get a cobra 29. its a much better radio. Also, if you haven't, when you get the cobra 29, read the part about SWR in the manual.

You must tune the antenna. If you do not, you will destroy the radio over time.

Press the mic button in and get a humming noise... worked for about 4 hours yesterday then started this noise again..

Is it the correct mic for the unit? also play with the volume knob. Some times when they go bad when you wiggle them you get a buzz noise.

I set the swr on my antenna and it keeps moving i have a cobra 19 dx iv and i just installed a net window mount antenna 27" on my back window that has factory tint.

1) if you are talking, your SWR will most likely move. You must take the reading while not modulating, (talking into the mic)

2) Window mount antenna's are GARBAGE. they are worthless. BAD BAD BAD. You wasted your money. Get a mag mount.

3) if you are not in an open lot, your SWR's will be different due to structures reflecting signal back. Always take your SWR reading in an open lot.

4) You could be experiencing Common mode currents. Normally the signal travels on the inside of the coax ground. Common mode current is when the signal is traveling back down the coax on the outside of the ground in the coax. (The biggest cause of this would be the window mount antenna). If you want to keep that garbage antenna, then you can make an RF choke in the coax. The best solution is get a better antenna. Here is how to make the choke. As close to the antenna as you can, take 6 ft of coax and loop it uniformly laying each coil next to the other. use electrical tape to hold it in place. You want 6-8 wraps. You want a nice uniform coil.

Just get a better antenna. Window mounts are the worst. You get horrible receive and horrible transmit. Get a wilson 500 mag mount. It will work so much better for you.

Volume control inoperable

spray some tuner cleaner in the volume and rf gain pots and work them back and forth. Have you tried an external speaker to see if stock speaker is blown? Also improperly installed talk back can cause this

Assuming you have a good SWR, either ditch the power mike or the truck.
