if its new send it back to connex

remove top and bottom covers and locate the resistors on the bottom of the main PCB. Unsolder them and remove them ,thats it. check out cb tricks for a picture of what to do .

should be the standard 3 pin plug for any radio .

first of all if you do not have a ham license then you should even worry about getting on any band other than the AM band .

get a K-30 antenna ist magnetic if that dont work your speaker in the Cb is broken

audio i.c

only the CB band to TX on.. you may RX on any frequency. ch.1-ch.40 am and SSB if it had it.. are the FCC allowed channels. yes there are people on those other bands. user beware.

Your connex should have a know with letters on it A,B,C,D,E,F, Look at the counter and set that knob to C whick should be the CB frequency.

Hello As a general rule of thumb all radios should be connected directly to the vehicle 12 battery. This connection cuts down on vehicle induced noise and allows the radio to have access to the full current it needs to operate at full efficiency. Make sure there are matched fuses in the positive and negative leads going to the radio. Hope this answers your question.

Hi,

Based on your post/description:

1. how do i set the swr
Normally SWR are calibrated on your operating channel (where you usually stand-by). This is to maximize transmit power and receive sensitivity. To set SWR, switch to channel of your choice, switch SWR control to CAL, key or press PTT, while pressing PTT rotate ADJ knob until max deflection of needle on meter, release mic, switch control to SWR, key/press PTT, needle reading/deflection is SWR for that channel.

I would suspect that your SWR will vary from your current 1.4. This is because you have too big excursion of channels (240 channels).

2.reading a 1.4
This reading is good enough and should do. However as earlier stated, you seem to have 240 channels which would mean that your radio + antenna moves in a wide bandwidth and since the antenna tuning is affected by frequency, your SWR will also be affected by channel.

Best if you can further lower it down.

3. some cb cant get me
This is because the standard CB radio is only 40 channels. The next would be a 80 channel and then 120 channels.

4. is it my radio
Yes, you have a wide coverage radio almost an extended 10 meter rig.

5. do i have to set my radio on high or low to set my swr
I will assume you are referring to power output, set it to HIGH when doing SWR calibration

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

Good luck and kind regards.

On the RF Hi Lo switch do you have power? Is the switch ok? That switch regulates the TX power and if it is open, you have none.

Did you replace any components such as the audio chip,the audio cap.near the modulation transformer ? Could be the final or even the driver .Did you follow a service manual as to how to re-tune it ? Eliminate the positives to find the negatives.

i have a 10k on a quad mag mount my radio is a galaxy 98vhp peaked and tuned and i talk every where i key on base stations no problem that antenna is a beast you have some issues goin on over there u need to get that tuned i have a flat 1.0 and i run around 250 true watts and my swr never goes past 1.1 you wanna be loud n talk tune that puppy right biggest thing for them is ground best thing is to run it on a huge magnet best ground there is and you have to have good coax that has alot to do with it just tiny little things you have to check make sure everything is set up correctly

lack of a noise filter on the DC voltage supply to the radio http://www.jaycar.com.au/Sight-%26-Sound-Car/Car-Audio-Hardware/Car-Hardware-Accessories/10A-DC-Noise-Filter-(Improved)/p/AA3074 or lack of grounding maybe https://www.youtube.com/watch?v=dY3gD-j4SVs

unless you have the equipment to do this.. please take to a radio store. have them do it.. its free. or they shouldn't charge to do that service.. unless it needs a major factory alignment. also they shouldn't take out or clip anything in the process if they do find you another place LOL..

pin 1 gnd pin 2 audio pin 3 tx pin 4 rx

Brand new. ? it is still on 10meter... there is a conversion to make them work on cb frequencies. although they should have tuned up and converted when you purchased it.. at no cost...

Yes.

1 ground 2 audio 3 tx 4 rx - exports do not use

That style will get about 60w PEAK.. on older styles.. the newer Mosfets will do about 30-40ish.. Meters, are preference.. most are just RMS styles. and you wont see the Peak reading which is fine. there are alot of meters and brands.. Bird, Dosy, MFJ, Siltronix. they all have pros / cons. if just want simple workman makes some lower end styles. also para dynamics.. there are some MFJ and other brands that have cross needles that show both power and swr at same time. but they will start in the $60ish range and go up from there.
