20 Most Recent Magnum DeltaForce CB Radio - Page 3 Questions & Answers

If your asking for an internal adjustment,you need to be a qualified technician to do this and the radio's schematics..which I don't know either answer to,so external adjustments would be mic gain knob,you can also gain modulation by lowering the output power knob,both can be adjusted to get the most forward swing by watching your meter swing when am or sideband transmitting.If you are using the stock mike,you could also upgrade to power mic properly wired for your radio.If you are a qualified to do so,there are online sites that have info on upgrading the modulation to this 10 meter radio by adjustments,modifications and add on parts,which does require an amateur license to operate unless modified for cb bands and only transmits on these bands..according to fcc rules.

I have no info on the 5 pin as i know the OmegaForce version has an addition mic plug, i figure yours might also.

Here are the Pin outs for different mics that will work with your radio. If a wire is not listed then you cut it off. It's best to keep the wires as short as possible no longer than a half inch is suggested. Normally the Cobra pin out is standard for most radios.

You can say you hooked it up backwards,it blew the diode inside,this would be hard for you to fix without the right equipment.Please don't change the fuse in line and keep tring it because the more times you do the more chance you're giving it to take out more components.Take it to a shop and tell them what you did,It can be fix so don't let them tell you other wise.I own my own shop.

maybe this will help

i have a royce1-621 is there a way to put a 75 w amp in it ???

thanks [email protected] 708-599-1223

This sounds to me like a bad microphone. there are not that many moving parts in a radio so it is either the PTT switch or the cable to the mic.

hi the easiest solution i find is to keep the ptt pressed remove wires from connector ,then place connector in radio try two wires at a time you will finally get the transmit wires then all you need is the audio ,you can flick over to ssb to sort the audio hope this helps you goodluck

I can work on any radio. How can I help?

hi sounds like wirering problem ,open up the mic casing and check for broken wire shorted wireing tidy up any lose strands of wire all it takes is one strand to cause this problem you can also get switch oil and spray a small amount on switch goodluck

Do you have receive? Make sure the radio is on CB and not PA. It happens. Try a different mike and make sure that is not the issue. Make sure your SWR is 1-1:5 and no higher than 2. You can loose a lot of your signal from a high SWR but SWR will not make it so you have no audio. You may have to replace the final transistor. Try this too. Take an external speaker and hook it into the PA port in the back of your CB and switch your CB to PA. If you key down your mic and hear your voice out of the external speaker your voice chip is good. Let me know if any of this helps. If I had a CB in my shop, this is how I would start the checking. Good luck.

Use a known good external freq counter, and do the tx alignment. that will put your meter back on showing the right freq when you are..

any mic will work on any radio. just need the right wiring or ohm impedance(new mic on old radio)..

Hi. Have you accidently reversed the positive and negative wires?, if you did then a diode has gone short. The rig has a protection diode across the 12 volt input inside the CB. This diode will most likely be short-circuit and stopping the radio from operating. Replacing the diode with the same type will usually cure the fault. If you cannot source a replacement diode, just removing it will let the CB power up again but be warned!, this is not recommended as if it were to ever be wired incorrectly again, the resulting damage to your radio would be catastrophic. Hope this is of some help to you.

sounds like the power to the echo came loose/ shorted ie.

Lower or turn off your talkback, and or lower your mic gain.

Channel 19 is 27.185 Mhz. This can be found online or you can call the good folks at (706) 270 3829 and they will happily email you a chart containing that info for free.

Push the EMERG button and try it, or the CH9 button. hope this helps..
