Make sure that the mike gain & RF gain controls are turned clockwise & the squelch is counter-clockwise.

I recently bought a Connex CX366CE. I plan to install a SLMM-1 SUPER MOD AND SWING POWER MODULATION kit. I plan to hook it to a Viper 25,000 watt antenna. Is this going to work? Do I need an antenna tuner...


you should be fine, check your swr's before and after.a swing kit only throws the carrier and adds more modulation. the connex is a good radio to start with,you should be fine, with the mod kit and radio you will never reach 25k on that antenna with this setup. just make sure the antenna is tuned rite for optimum operation(low swr).

Handheld Radio Shack CB radio TRC-230 I can hear people but no one can hear me


First, lets make sure that the unit does transmit. Get a power meter and see how much power it transmits. If no power is being radiated, you need to have a technician check out the unit.
If you have power then pick a less crowded time to test out if anyone can hear you. Other people with more powerful equipments can only be a problem when you are transmitting on the same channel and both of you happen to transmit at the same time all the time. Chances are remote that this is your problem. Good luck. es

Bought radio at Hamfest. Hooked it up worked flawless. Great ability to fine tune signals. Let a tech talk me into installing echo board. He tried two new boards. They wouldn't work. Told him never mind ,...


The guy who was really not a tech probably didn't hook the mic wires back to the mic jack correctly. that will cause the radio not to TX or RX.

Next time make sure the tech knows what he is doing, and check on line for cb radio shop blacklists to make sure that one isn't on the list.

This guy owes you either a new radio, or pay to have that radio repaired.

If both echo boards didn't work, he doesn't know what he is doing, because he put them in wrong.

I got one of these at a garage sail for really cheap, i was checking to see if it worked at home. I have a scanner and found a channel that my scanner picked up. Well as soon as the scanner gets about 6...


just because you hear it on the scanner,doesn't mean that the scanner is on the right frequency. You might just be getting RF saturation because you are close.

Most scanners do not cover the 27mhz range which is what a CB is on. If your scanner is no in 27mhz, then you are just getting RF saturation, and its just bleed over. 27.185 is channel 19 on a CB.

The radio probably works fine. You will need another CB to really test it.

set it up in a car, with an appropriate antenna, and a proper SWR reading. (antenna needs to be tuned to get a good swr) and then go on channel 19 while on a highway and say, "Break one nine for a radio check." if the radio is working some one will tell you "Its working." You will most likely hear truckers on the radio before you even say anything.

Low transmitting range on Cobra MRF55


Hi dstrand, sorry you are having a problem. I will need some more info if you can. Is this radio in a base situation or mobile? Have you had any work don recently? Have you changed anything on the system? (Microphone, antenna, coax, etc)

Haave you checked your swr recently/ If yes, did you use a seperate meter or did you use one built in the radio?

Hope to hear from you soon.

Static


Hi,

CB radios use a frequency range and technology that is prone to noises both atmospheric, and man made. The height and gain of your new base antenna may produce more static than you may have noticed before. The question is 1) is the antenna close to any power lines to your home, 2) do you notice any increase or decrease of received signals compared to your mobile, 3) is the static steady or does it come and go.

Codra 29ltd clas. trans and receve only at close range


Try a different antenna. In my opinion, Moonraker antennas are the best. However they are the biggest of all CB antennas. They're smallest antenna measures close to about 40ft long. They're made for long range communication. They are pricey but well worth it. I recently got a Moonraker for my Galaxy DX2517 base station, it has a 50ft metal whip with power supply box which increases the output power. I can talk all the way to canada just using the pure power of my radio, and I live in Virginia. I'm telling you, if you get a Moonraker, you're set for life. And about your radio problem, umm, it might be your antenna, sometimes when you have a dual antenna input, it messes with the modulator and the frequency amplitude. It's best to just have one antenna.

Hope this helps!

Super Star 3900 GHP


Can't help you there. It's most likely that you screwed the modulator up by extending the frequency range. I used to work for Galaxy and I know what happens to a radio when amateurs try to modify them (no offense). If you modify a high power radio such as your Super Star, you're bound to have modulation and SWR problems. In expert advice, never do amateur radio modifications to a high power radio. If you want a more versatile radio, get a Galaxy DX 2517 CB base station. The DX 2517 has PA/FM/AM/SSB/USB/LSB/CW modes, and bands A-F, and a frequency range from 25.615 to 29.205 MHz. The Galaxy DX 2517 has modifications that can be done right at the factory, they are optional however. The only thing I find annoying with the DX 2517 is that it's bulky, it leaves no room for any competition. When it was designed, the engineers left space saving out of the question.
Anyway, Good luck
and
Best Regards,
