Question about Cobra 29 LTD CB Radio
I believed i did the swr calibration correctly .i have attempted to use the cb radio,all wires,mic,antenna, are put in place correctly, and yet i still cannot received or transmitt, meaning that when i try to adjust the squelch i hear nothing even after adjusting. I even drove next to the highway to make these adjustment,as the truckers come by and yet nothing,pa sytem works from existing hookup from other cb radio i had.By the way i have brand new cobra 29 ltd classic that i just purchase.i have try 2 different antennas,both are good ones.
RF gain should be all the way up. Turn the squelch all the way down. Turn the ANL/NB to just ANL.
Turn the dynamic up at least 3/4.
Once you have confirm you can receive and transmit, then you can turn up the squelch up until white noise just stops.
Make sure you are on 19 by the highway. Key up and say break break one nine, can some one give me a radio check please.
you should get a response.
Your RF gain is how much you receive. the higher it is the more you receive. In normal operation there is no need for it ever to be less the all the way on.
Squelch is just to knock out fuzz, and if you only want to hear people close not far. A little less then half way is a basic setting.
the ANL switch is the automatic noise limiter. if you have interference from your vehicle, like engine noise, turning this on will quiet that. If it is extreme engine noise then switch it to NB, noise blanker. It is just a more intense setting.
your dynamic is how loud your audio is. if its low or all the way down, you will not transmit audio loud enough for people to hear. If its a stock radio and has not been tuned, if you turn it all the way up, that is fine.

When you key the mic, does the TX (transmit light) come on and does the TX meter swing to the right? When in RX (receive mode) does the needle bounce even though you can't hear anything?
If the meter DOES swing and you get the TX light, plug in an external speaker to the back (there's a spot marked for this, be sure to plug it into the EXT SPKR and not the PA hole) if you can hear now, the problem could be a faulty speaker wire or the internal speaker has become unplugged. A soldering iron can fix it if it's a broken solder joint, you'll have to remove the speaker cover (the bottom radio cover) to see. If it's unplugged or not plugged in tightly, you'll see this too. Gently push down on the speaker plug and see if this does the trick. If the speaker is blown, you already have the radio open, unscrew the speaker from the cover and unplug it from the circuit board and install a replacement speaker. It's quicker and a lot easier to just go buy an external speaker to begin with though.
If the meter doesn't move at all, when you key up the mic, try another mic. You can usually purchase a replacement mic inexpensively, and it's always good to have a spare mic on hand anyway. It is possible to have a brand new setup out of the box with a faulty mic, it doesn't take much to break a solder joint inside the head of the mic.
