Antenna is probably not tuned for best SWR. He is beating the final in the radio, and its over heated after about 15 minutes of uses, and if he keeps using it with out tuning the antenna for lowest swr, he will kill the radio.

Connex 3300hp big betty transmits fine on low power setting but when switched to high power hardly any modulation


well fellow truck driver here goes. When you take any radio back to a repair shop they are required by law to set it back to its original settings. I could fix it for you if you ever got to Massachusetts but you need it now so I would tell you this.Take it to a very good cb shop , tell them what went on and that you would like that big radio sound back. thats it.

I have new cobra ltd new antannas and mounts can hear but cant talk


You say antennas,I assume co-phased,as long as they were installed correctly&adjusted for the lowest swr reading,we'll assume they are ok.Next step would be the radio adjustments ,there is a switch next to your meter that must be set to s/rf,another switch for cb/pa needs to be on cb and last the knob for mic gain needs to be set at about halfway to three quarters depending your voice level and mic type used..are you using the stock mic that came with the radio,if so you should be able to transmit..look at the meter when you key the mic and talk it should move with your voice.If your using an aftermarket mic such as a power mic,make sure the battery is fresh and the correct type,this may also not be wired correctly for your radio if bought second hand..next step would be taking vehicle w/radio to a reputable cb repair shop or technician to evaluate.Good luck and hope everything works out.

Vibrations on the small cb's make the internal circuit boards come loose and its intermitted or will not RX or TX.. Check the antenna with another cb. using an SWR METER.. or have someone check it.. SWR should be free if you take it to them.. to check.. Make sure the antenna, mounts, and coax are ok.. if soo then its in the cb itself .. Email us if you need more help or need the radio looked at, the post office has flat rate boxes cheap nowadays. were in Temple, TX at the CB SHop.

what kind of meter? I would go by what is in the radio unless you are using an analyzer.

You may also be getting common mode current. take 6 to 8 inches of coax and make a tight coil about the same size as a spray paint can. Hold it together with electrical tape.

Use the meter in the LX LE to set the SWR then check with the other meter.

Cobra 29 ltd classic side mic


First off I dont believe anyone to peek and tune but anyways. Make sure your mike is for the radio wiring. Next the guy that rigged it up might have gave you all the channels do all your knobs work??? usually you can tall as you get someone to talk with you a few blocks away and start, start turning and flipping switches till you can hear him most likely the guy that did the work on it messed it up. for a filter use a farite choke from radioshack on the mike wire.

How do you put a new connector on a cb cable?


Hi,
1) Get an ohm meter.
2) open the mic
3) unclamp the mic cord at the plug and slide the plug case up the cable to enable you to see the wires soldered to the plug.
4) use the ohm meter to check the wire continuity by checking each color wire one at a time. The meter should have full deflection if the wire is OK, make sure to wiggle the wire to make sure it is not intermittent.

Personally I would just change out the cord. If it is going the rest of the wires are going too.

Cobra 148gtldx low vol squelch on fm


Hi Mate, the problem you are having in not uncommon in the
COBERA 148 GTL. I suspect that the problem lies in low value uF electro caps drying out (electrolite) causing power down and frequency drift. The capacitors are in two forms..tiny blue tantalum, and standard radial base caps that are grey aluminium
cans with a black stripe,it would be a job for a skilled person in electronics to replace all of them. The square metal cans with a screw ferrite slug are what you use to tune the radio, and as there are lot of them ,and you don't have a circuit diagram ,it would be pot luck finding the right one/s. What you realy need to know is all electronic devices age and hence, no longer do their job.
it would cost more than the set is worth to rebuild it,but if you have the skills ,it can be done. am cb with usb / lsb are a thing of the past now and you would be better off buying a used set that is still in top working order. The uhf sets are useless as was the am sets depending on what you want the sets to do, in convoy.... great....in remote country....useless. Having said that the am/usb/lsb sets are the best of the three because on ssb they tx on about 12 watts rms so you have a better chance of making contact, but don't count on it as hf cb is no longer in
common use.
GOOD LUCK flyingfox@people.net.au

Poor TX RX range


Hi,

Since your concern is both on receive and transmit, the common denominator would be the antenna system. The antenna should have a metal mounting to serve as the ground plane. Said mounting/ground plane must be electrically grounded to the rest of the truck. The next area to check would be the PL-259 connector. It should be soldered/connected right with no shorting. Next would be the cable which should be low loss RG-58. Last to check would be the SWR of the antenna. Most mobile antennas could be fine tuned to a specific frequency/channel by adjusting its length. There would possibly be 1 or 2 Allen screws for this purpose. In some cases, it may be necessary to trim off a few mm of the rod.

On your concern re modulation, am afraid that your radio has built-in limiter so as to prevent over modulation and comply with European restrictions. Additionally, the Midland 48 Plus has been programmed to transmit only 1 watt in AM (4 in FM) when the display shows D or D2. Additionally, you might want to consider a power microphone.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
