I will answer the question. Figuring that 10 amps is continuous not peak. 10 amp multiplied by 12.5 it should be good for 125 watts. But you are on the ragged edge. I do agree you should lower dreaded key but you did not ask that question. But a swing kit will solve that. That is amusing SSB and the 80 watt cobra 29 comments.
you will need a jumper cable to go from the box to the radio then the antenna plugs into the box at the antenna connection point.Now for DC power you will need at least some 12 gauge wire with a fuse connected to the pos and the neg. Then you connect it to the fuse box and a ground . I personally would not use one ,if my radio cannot out do yours then so what.If you can't hear my radio within 12 miles of me then I will talk to you when you get closer.You want to hook one up thats your option but I don't even want one.
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.
IT could??? peak power, 14-15volts yeah.. the 4300 should put out 80w by itself.. as long as you have a low deadkey ie 1-5watts it should be fine. just don't put high wattage into an amp like that.. it will get hot QUICKLY.!!.. make sure your swr's are low low low.. 1.7:1 or lower... so your not getting reflected power... i would put a wattmeter with swrmeter like a mfj. or vectronic cross needle meter inline just to monitor it.... they go for $75 @ most places. Good investment... call email if need more help
3 Amps is probably not enough for this radio. To test this diagnosis, conenct a car battery inline with your charger or just the battery to the radio. BE SURE TO HAVE A FUSE ON THE POSITIVE power wire and observe polarity ( + and - ) . If the radio works like it should, you now know the power supply is not big enough. Try a 10-15 amp supply. The manual shows the radio to have a 4 watt ouput on Am and 12 watts on SSB. My experience with Galaxy radios says go with at least 10 amp supply. Here is your manual and a service info page. http://www.cbtricks.com/radios/galaxy/dx959/graphics/om_dx959.pdf
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.
