Make sure your Antenna SWR reading is 1:2 or better, also have your antenna as hish as possible with a sufficient groundplane and remember that indoor antennas will not be anywhere as efficient as an outdoor one. If you have lots of surrounding buildings or trees this can effect your TX and RX.

if you post on this site the wiring for your mic I'll tell you how to get more modulation. there are a number of people looking for this wiring and I don't do wiring unless I really have to. Now if you open the radio and look at the components side you will look for a transformer with a variable real close to it. Thats the modulation transformer .now you will need a modulation meter for this part. look at the needle and turn the variable to the left as you talk on it. If the modulation goes down then crank it the other way and watch the needle go up . Simple??

Looking to buy connex4300hp for 150.00.think its a good deal but dont know that much about it.gonna run 18ft coax to wilson 2000 w/astatic do i set-up for best performance?=bands,knobs on...

A new unit goes for $280 range
then conversion to run cb freqency $30.
Tune-up $50 you should get 70 watts older units 90 watts newer units

As far as the knobs go
Band D with channel 19 selected this is 27.185 citizen band if you radio has had the channel expansion done other wise it is not accessible.
Select AM
10 khz switch should be off
mic gain know depends on the tuning of your radio and mic choice.
rf gain full clockwise best reception you will just have to play with this knob and the squelch to your liking
Make sure the thing is working properly before you buy capacitors dry out and the connex radios are know for problems with their pcboards. good luck

Dont know how to use the swr meter on my radio

With radio turned on

1. Switch the first switch (S/RF SWR CAL) to CAL setting
2. Key mic up &
3. Turn SWR CAL knob while still keying mic until the needle is on the red CAL arrow at the far end of the meter scale. Unkey mic.
4. Switch the first switch back to SWR setting.
5. Key mic up again and record SWR reading and adjust as needed.
6. When done adjusting put switch back in the S/RF setting for normal operation.

Do not flip the switch with the mic keyed up.

Cobra 29 ltd classic needle doesn't work correctly

Don't worry about the meter in the radio. They are only close to actual reading any way. Just get an external meter. you are better off in the long run, and you don't have to mess with anything inside the radio if you don't know what your doing.

If you must have the meter working correctly, then take it to a truck stop CB shop, or any other cb shop and have it aligned. It should cost about $30. There is equipment needed to align a radio properly and the cost for it far exceeds what an external meter, or having a cb shop align the radio.

I can hear people talking, but they can't hear me, or they say I sound like an alien

Check to see if the meter needle is swinging backwards when you key up. If it does your final may be bad. If the needle goes forward and others say they see your keying up but no sound your audio chip may be bad; especially if you have tried so many mics and antennas. If your radio has a swr warning light and it comes on this could extremely limit your range and others may not hear you and contiued use will damage your radio. Good luck!!!

When i talked no one can hear me but it move move the meter.

This may be a simple and very basic problem with all Cobra models. Honestly I wouldn't ever choose a Cobra, they're cheap radios. Instead buy a Galaxy or Uniden. But have you tried the Mic Gain? If not, turn the Mic Gain knob fully clock-wise and try asking for a radio check, if this doesn't solve it, you also might want to check the microphone's connecting ports, the connecting ports may be damaged or corrupted, if so, you can replace them by buying a new connecting port. If this doesn't work, your transmitter may be damaged or corrupted, this can be fixed, but it is expensive, you're better off getting a new radio. And don't forget, some truckers are dipshits (no offense) and ignore a lot of people.
