Cannot select USB or SSB.Displays LSB or LISB? Very poor reception


On the Satellit 750 you have a button marked SSB. If you have selected a shortwave band then you can press the SSB button. Pressing the button repeatedly will toggle between LSB and USB.

You will need to know the exact frequency and the broadcast time, and the side band. Turn the radio on. Select a frequency which you know carries SSB signal and wait. Those that broadcast on SSB are not radio stations, maybe ham radio operators.

You can also select a short wave band, press the SSB button once or twice to select the side band and launch the automatic tuning system. It will scan the meter band and stop for a few second when it receives a strong enough signal. If you are able to perceive a clear signal on LSB or USB then you found a broadcaster. Some radios just have SSB and you cannot choose the side.
Personally, when I buy a radio I always insist on SSB but I have never been lucky tuning in an SSB signal. I keep trying once in while.

I need more transmission range for free


A lot of people will say that you need to peak and tune the radio to get more range. And it will, but what it really comes down to is your antenna system.

Even with the best peak and tune, if you don't have a good antenna system, it won't do you any good.

You need to make sure the antenna is a good match. If you don't know what that means, then you should refer to your manual on SWR. The antenna has to be tuned so that transmit power does not get reflected back into the radio. If that is happening, all of the RF power is not leaving the antenna, and you are not getting out as good as you can.

Once you have a good antenna system, then you can worry about peak and tuning. But for a peak and tune, I charge.

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.

How do i peak my connex 4300hp?


They probably still have more experience then you do! You should be okay as long as you tell them that you just want a basic peak and tune. Nothing crazy. If you ask for super mod of some kind then you will end up with a radio with problems.

You can also send it out to have it peaked and tuned.

50 watts isn't bad tho. I have never worked on a connex and don't know much about them so I couldn't tell you who to peak it out.
