Vco out of range.. Tuned wrong.. Very common.. It probably kept you from burning it up since your swr will get too high even 10ch above 27.405= ch40.. Bells cb or finetune cb can allign it correctly.... Imo stay on cb .. Your antenna is not broadbanded enough and you dont have ssb and its not legal..

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.

Will not stay on 11 meter turn it off comes back on 10&12 meter will not transmit am or ssb recieve ok. rci 2995dx.


Hello janetsue, If this radio has the blue or green screen LCD face then this is a default that is built into the radio. It depends on how the radio was "converted" when it was bought new.
It will not key up on 10 or 12 because of the default. A little more info supplied would be real helpful,,,, Let me know, Mechanic

That is correct about the SSB. Now before we go any futher is this set still under warranty? If so or if it is just a little out like a couple of months contact Philips @1-888-744-5477. PS. on the front of the set where the power button is how mant times do that led blinks.

Measure the connector from the logic board to the power supply the second pin from the left it will say Vs_ On if the set has 3.1 volts the problem is the SSB or the logic board. On the logic board there should be a solid led and a flashing led that shown that data id flowing and the problem is the SSB. The SSB is easy to replace just remember what you tokk loose and from where. You probely will save money that way. If the set is in warranty or just out of warranty contact Philips 1-888-744-5477 and see what they can do first.

Your problem is a faulty changeover relay on the circuit board. It is a small black device , and may have the brand name MRATA
etched on it (the switchover contact points are stuck together)
