The audio amp Transistor is most likely going out. when you have full wattage on a dead key and no or little af output.

Trying to find the right size linear amp to hook up to my Galaxy dx 949. I want max in/outputs. tired of being talked over. I have a Golden Eagle 150w amp, but have not connected it


That linear will be good for 100 watts of clean power. It has two MRF455 transistor which are 60 watts a piece. The cb will drive it with the carrier or dead key reduced to about 1.5 to 2 watts but i suggest that you read the linear's power while adjusting dead key not exceeding the 100 watts pep with voice. An NPC mod would be a good addition to get the modulation up with a low dead key.

Before you start the projection make sure you antenna system is in good condition high SWR will smake you linear in a hurry.

In factory condition 949 galaxy with a 3.8 carrier it will drive a 667v TexasStar. It is a low drive linear that will end all disputes as to who has more power. 8 out of 10 birds that escape will die of cancer withiin 72 hrs. Ok could not help myself. I would not suggest that unless you just want to damage other peoples receive. The v is for variable power. Hope this was of help.

Need a good setting on dead key for connex 4300hp for both low and high setting....its putting out almost 130 watts, thanks


put it @ 1-5 on low and max of 10-15w on high so it doesn't kill the transistors 130 is too high.

Can a 19 ultra power be turned down to 1 watt? If so where?


Yes it can, but it requires the addition of some components. It isn't really a straight forward install. It needs some reworking. In my opinion, not worth the trouble.

Sounds like you want to run a linear amplifier. If you really want to run an amp, get a better radio to do it. There really is no other reason to lower the dead key that low. Also, 1 watt might be too low. May not drive the amp well.

If you just want to make the radio swing, 1 watt is way way too low. You will have barely any carrier and the radio will sound like ****. That radio stock dead keys 2.5 watts. That's perfect for swing. Now you just need to have more modulation. Find DM1 and unsolder 1 leg and pull it out of the board. Now you will have full modulation. You will deadkey 2.5 and swing to about 15 watts.

If you want to run an amp, get a good radio. If you like cobra, get a cobra 29. They are fairly cheap, and sound amazing. As well it is real easy to lower the dead key in that radio.

SSB off frequency


Hi, my name is John. Welcome to FixYa. It will take a tune-up that involves some expensive meters. The tune-up should be only about $35.00 to $45.00. The 148 is a great radio, I have three myself and they are great. Only your local licence tech. can do it, or any CB shack. Good luck and thanks for choosing FixYa...John

Galaxy saturn tubro 100 watt power is sticking after key up.


Not sure what you mean completely. If you mean, when you key up, it keys at 100 watts and stays, then this is probably not a problem.

If it doesn't swing, it is either the watt meter you are using, or you have the power up too high, or both.

I usually key my saturn turbo around 80 watts. You have to be careful with these radios. they get hot fast and when they do, they get whacky. Make sure you have a PC fan plowing on the heat sink on the back.

The higher the dead key, the less swing you will see.

Now as for the watt meter....

There are a few types of meters out there. The 2 most common are ones that read AVG, or average watts, or PEP or Peak envelope power, which in short terms is your Peak wattage. Some meters do both.

An AVG meter will not read peak wattage, or swing. So if you meter is an AVG meter, or is set to AVG, then it will not read swing, and will show you your dead key, and that's it. Some times the needle will move a little, but it is not showing your true swing.

All in all a PEP meter is a loose representation any way, because you really cannot get an accurate reading when there is modulation. But it's close enough. You would need a spectrum analyzer to really see what you are putting out with modulation. AVG with no modulation is a more accurate reading however you cannot see swing.

Now PEP while transmitting in SSB with modulation, would be accurate. Just not AM, but like I said, its close enough and is what every one goes by.

I don't know if your Saturn turbo has been modded or peaked and tuned but, you should see a max of about 170 to 200 watts swing on that radio if its been done right. But you will need a PEP reading meter to see that.

I wouldn't run it past 80 watt dead key for long. With that radio you should really only run what you need. For instance, when I am using mine, I start at around 70--80 watts, and do a check, and if it's not strong enough I bring it up a little, until the audio sounds good to who I am talking too.

Like I said, you have to keep it from getting too hot.

Does anyone know the pod too turn for lowering the watts on my connex it is too high and i would like to turn it back also the modulation thanks


You have to adjust the high key first so make sure you're rf power is on high, hope you have a meter set it on the 20 watt scale, key up and turn vr 13
located in back of radio infront of where you're coax connector is until it keys around 12 watts, thats where most connex 33hp should be set,now go to low power and key adjust vr 16 right net to the otherone down to about 3 watts, now you can drive a liners. Mod is Vr 2 right below them two. whistle in mic and turn to get the mod you want.

Tunring up a cobra 150 gtl/dx


Um... What?? This is hooked to a switch? CB radio by FCC regulations is only supposed to have a max of 4 watts total output. If you can flip it to 7 watts dead key, you are doing really good. It won't do much more then that. It sounds like its set up to run on a linear amplifier, which cannot have more then 3 watts dead key transmitting into it.

Dead key, and modulation are different. You may have a meter that only reads dead key, and won't see the modulation. This radio is probably swinging close to 15-20 watts. you need a meter that can read PEP, Peak envelope power. Cheap meters only read AVG, or average power, witch will only show your dead key.

7 watts dead key is really good for that radio.especially since stock only has 4 watts. you cannot get any higher then that without changing finals.

at 3 watt dead key, or 7 watt dead key, your modulation wattage is still swinging much higher.

Also, you will get more swing with a lower dead key any way, which is better if you want it to be loud.

Leave it alone. its probably set just right.
