Amplifier for SSB

[Radiomatrix]

After zooming-in on a photo of the power supply, I am assuming the power cord attaches to the N L and Ground terminal screws on the front of the power supply. The instructions probably indicate which color wire attaches to the corresponding terminal screw.

I ORDERED IT A FEW HOURS AGO-S350-12.

First off that tech you took it to is an idiot, second if the radio is only putting out 2 watts then there seems like there is something wrong with the radio. The Washington is a older radio therefore there could be capacitors that are leaking and need to be replaced, the RF transistors could be going bad. Yes two watts is the preferred output into a cb amp but there is more going on here. The radio needs to checked over by a qualified tech(hard to find in the cb world) and parts replaced. The radio could close to dieing completely.

Well, I am bracing for a response from this shop. He is an awfully nice person and I hope i wasn’t too rude or abrasive.

Welcome!
The 203 is hard to beat, I have a few of them. With a stock cb, lower the carrier to about 2 watts and you will be good. 88 Radio has the best deal going, two for $150. They have a warehouse in California, I have bought from them several times, no problems.

If they are in China then their time has about a 12 hour difference. I have never tried to correspond with them.

Megawatt has great units, and they don't make static in the receiver like the cheap ones.

my megawatt 30w power source arrived yesterday and i set it up and dialed in 13.8v. I turned it off and on and the voltage was spot on as soon as it is turned on. Does anyone have any ideas on a stand for this thing? He provided specs on the screws. I hooked it up to a mobile radio to test it.

I mounted mine to the underside of my desk.

I wrote the company this morning and heard back from the owner.
I like this one: http://www.megawattpowersupplies.com/assets/Big_New_Stick_33_Amp.jpg

you set the voltage with a set screw and a volt meter. KISS

Megawatt makes a 50 amp supply. 50 is adequate for your needs. If you need more, just add another one on it.

55 watts is too high, I'd go with a 25 watts dead key out of amp

Thanks again for the tip.
I've been monitoring the power supply volts quite often. 13.8 volts was too much. With 13.0 volts from the power supply and one-watt from the radio, the dead-key out of the 203 is at 25 watts.

Keep those paper clips away from the top of the power supply.
What did you use to attach the + and - wires to the power supply?

13.8 might be too much for the 203.

My amplifier just arrived. It is tiny. I have not seen one in recently memory.

Remember to keep the dead-key at 35 watts and below. Do you have a decent wattmeter to verify the dead-key or are you going to induce the two-watts from the radio and "go for it"?
