Fix my connex 3400 hb sideband button


Hi there, if you are talking about the Connex CX 3400 HP there is no sideband or SSB on this radio. It is only AM and FM 10 meter Ham radio. Many people do modify these radios to include the 11 meter frequencies which is the CB band. Maybe knowing the actual bands and their frequencies will help some too this radio does have 6 different bands ranging from (Band A. 28.015 thru 28.455) (Band B. 28.145 thru 28.585) (Band C. 28.115 thru 28.555) (Band D. 28.085 thru 28.525) (Band E. 28.055 thru 28.495) (Band F. 28.025 thru 28.465.) I hope this will help you. Bob

Ihave a gargeled recive sound


Check the position of the mode selector switch. You may be receiving a SSB (single side band) transmission that is not on the exact same frequency as you or, your radio is in AM or FM mode. You will need to select either USB or LSB (upper or lower side band) and vary the clarifier knob until the sound becomes intelligible. If the sound does not become clear, try the other side band and repeat varying the clarifier knob.

Conversely, if you are in USB or LSB mode and there is a transmission on AM or FM, it will have the same garbled sound. Try changing the mode to AM and the FM. If it does not become clear, it is likely a SSB transmission and you are not on the exact same frequency of the transmission you are hearing. Vary the clarifier knob until it becomes clear - or change to the other side band if needed and try the clairfier again.

The short story is that you must be in the same mode and on the same exact frequency. When in AM or FM, this is less of a problem as these are much more wide banded signals than SSB signals.

The 2990 is really a 50 watt 10 meter amateur radio - but is geared to CBer's as it is easily modified to work in the CB frequency range and the so called "free band" between USA's CB (11 meters) and worldwide amateur 10 meter bands. Be careful transmitting this radio on CB frequencies as it violates FCC rules for power output there - and transmitting in the 28MHz - 29.7MHz requires a valid amateur radio license. Fifty watts on ham frequencies is tiny compared to the 1500 watts permitted. Why not get your ham license (here's how) and leave the "Chicken Band" (and all it entails) behind. You won't miss it!

I hope this helps and good luck!

I have a Midland CB Car with no mike or a car power pluge, the model # is 70 - 336B and the serial # is 760408


Your midland CB will use a standard 4 pin wired CB plug which is most common for most mics sold today. Your power cord will be a standard 3 pin CB power cord which again is most common with CB's today. You need not purchase a "radio specific" cord or mic. Cobra, Uniden, Midland all the same mic pin out and power cords. Good luck.

NEED TO KNOW HOW TO FIX A RAIDO UNIDEN GRANT RAIDO NEED TO DETUN MY RAQDIO


Probably VR 10 on that radio. You are not really de-tuning the radio, just reducing the carrier power on AM. If you're driving something else, You may also want to adjust VR 11 for a reduction on SSB

What frequency do these run?? am or fm??


CB or citizen's band is in the 27 MHZ band. Its 40 channels long, AM typically, and on some models side band, or SSB.

It is only legal in the US to have a radio that operates in the 27 MHZ band on the designated 40 channels using AM or single side band only.

The MCB-30 is an AM only radio.

Just want to know if i should use my ll203 amp in am or ssb mode when running with a cobra CB radio?


What radio?? Does it have single side band(SSB)? If not, then don't use SSB.

AM - amplitude modulation
SSB - single side band.

If you have SSB, there would be a switch on it to transmit in SSB. If not, it is AM only.

Second, Has this radio been worked on to be able to run on an amp? If not, you will blow the amp.

A CB radio transmits dead keys with 4 watts of power, and transmits with 4 watts of audio.

a 4 watt dead key is too much for a linear amp. You will smoke the transistors. Also, 4 watts of audio is not enough to drive it properly. You won't get full power.

The dead key needs to be around 2 to 2 -1/2 watts,or what ever makes the linear dead key half its peak wattage., and the modulation (audio) turned up all the way.

It doesn't sound like you know too much about CB radio's. Not a big deal, you can learn. For right now you may want to take it to a cb shop and tell them you want a peak and tune, and set up to run a linear.

You can find CB shops usually at truck stops. Some area's they are other places. Check the internet for local shops.

SSB radio


If you are using the radio on a boat, then no, the grounding does not matter that much. However, an SSB transceiver would be hassle to install on a boat because of the amount of power they use to transmit. If the transmission is bad, try using the radio's internal tuner instead of the separate tuner. This may help improve the quality of transmit, however, some radios have a tough time clarifying incoming and outgoing signals and create a garbled sound when it receives a signal or when it transmits. If that doesn't work, then you can try grounding. But if you want a radio that doesn't require all this nonsense tning, you might want to think about investing in a Yaesu. They are pricey, but are one of the best HAM radios.
