The easiest way to check this is to hook an SWR meter to the antenna to see if the cables are ok. If the SWR is low then it would show no problems in the transmit and therefore the receive would be good.

SOURCE: Static and Recieving Problem

Even though cobra recomended this enteana for this radio does'nt excuse the fact that you definetlly need to check and adjust the (swr) standing wave ratio. I would also suggest you placing the enteana at the highest point in the center of the roof. Check the (swr) with an external meter not the one in the radio, and adjust the enteana accordinglly. SWR readings higher than 3.0 can damage your finals and have adverse effects on your receive capabilites.

SOURCE: transmitting and receiving

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.

SOURCE: red antenna warning indicator light stays on

The red light is a warning of antenna mismatch; when you hold the antenna, you are changing the match between the CB's output amplifier and the antenna. Try it with a different antenna or pick up a 'test light' (or test load) for CBs from an electronics dealer, I've also seen them with CB accessories at truck stops. If the test light fires off and the red light on the CB is dark, the antenna you have is junk.

When docking the headset cobra road trip and activate the ptt who hear me get a ring


  • Hi, I can help. When the microphone/earphone set is inserted in the radio itself the control is automatically turned over to the headset. There are no radio adjustment that need to be done. Just plug it in and use the PTT on the cord of the headset or unplug and use the controls on the radio itself.

  • Many don't know that the Cobra Road Trip and the Cobra HH 38WXST are identical radios. The only difference is the antenna sold with the two radios. The one you have come with a rubber duck style antenna and the HH38 WXST comes with a magnetic car mount antenna. So while the manualfor the Road Trip is hard to find the 38 WXST is not. Here is a copy of the manual http://minus.com/mTQOgU0yw

  • Read through the manual a couple times and feel free to get back to me with any questions you have.

  • Hope this helps.

I need the wiring for the mic


Hello,
Here is the wire diagram for several common mics in relation to a 4 pin CB. Most recent 4 pin CB's such as Midland, Cobra, Connex, Uniden, etc can use 4 pin mics. The wiring is actually depending on the mic rather than the CB so long as the CB's are 4 pin as well. Once you go back to late 80's the 4 pin design was a little different. Anything new it is simpler.
Stock Mic 1- Shield (Ground) 2- Yellow (Audio) 3- Red (Transmit) 4- White (Receive)
Astatic - 4 wire 1- Shield 2- White 3- Red 4- Black
static - 6 wire 1- Shield & Blue 2- White 3- Red 4- Black Yellow NC

Daiwa EM-500 Cobra CA Series 1- Shield & Black 2- Red 3- White 4- Blue
Galaxy DC-521S - 4 wire 1- Shield 2- Yellow 3- Red 4- Black
Galaxy CB-660EI 1- Shield & Black 2- White 3- Red 4- Blue
Sadelta 1- Shield 2- White 3- Brown 4- Green

My Squelch on my Cobra C.B isnt working anymore, Does that mean anything or do i need a new C.B?


It means either the knob or something in the squelch circuit has gone bad. Doesn't mean that you cannot use the radio, you will just hear static all the time when no one is talking. If the static bothers you, you can always back the RF gain down a bit. That will quiet the noise, but lower you receive range. meaning you won't hear as far away.

I can not get out on my cb i can hear them but they can not hear me its a cobra


turn the mic gain all the way up. Make sure the antenna has been tuned for best SWR.

Take your radio to a CB shop and have them peak and tune it.

Excessive static equally on all chanels on cb


You should always connect the CB directly to the battery as the accessory socket is full of noise. You also should choose a better antenna as these small glass mounts cannot hear signals well and magnify local noise. AM (CBs) radios naturally pick up noise as it is the nature of AM signals. Use your squelch to lesson this but too much can knock out you reception.

Is it my CB antenna or something else


First off, Midland makes a fine radio. Make sure your squelch is turned all the way down to receive distant signals (down meaning counter clockwise). The through the glass antennas are not the best thing in the world. I personally use a 102" whip and a 6" spring on a modified mirror mount. It is installed on the tailgate side of the tool box. The TX and RX is amazing. Wilson and K40 make great antennas also.

You Need to check and set you SWR on the antenna system. You may also have a bad coax or the ant studs ( mounting hardward ) for the antennas may be bad. It definally sounds like an ant/coax problem Good Luck
