Amplifier for SSB

[Recon]

Thank you.

My radio only puts out 2watts for some reason So this should be a good fit.

The only 12v power supply I have is this ancient relic In the picture That i hope to use for the linear.

sorry to ask but what is the pre-amp for?

What is PEP wattage?

I appreciate everyone’s help.

Peak envelope power

researchgate.net

• Peak envelope power (PEP) is the average power over a single radio frequency cycle at the crest of the modulation. This is a Federal Communications Commission definition. PEP is normally considered the occasional or continuously repeating crest of the modulation envelope under normal operating conditions.

This is not the best method to test PEP. With the mic button keyed / depressed and you whistle into the mic or increase your voice volume, that would be the PEP. Don't get too wrapped up over the axle on PEP.
I think you should start looking for a technician in your area to get you on the right track before you damage your equipment. First-off, you need a quality Power Supply. Next would be a quality SWR Meter, a quality wattmeter which can measure carrier watts and PEP watts.
Fifteen minutes ago, the dead-key on my radio was 2 watts. The 2 watts was a little high for the 203 as dave 457 informed me. Maybe the 2 watts on your radio will be too much for the 203.

The pre-amp amplifies the incoming signals to help pickup weak signals. For most people they normally are of little help but sometimes they are helpful. P.E.P is the output wattage under full modulation/audio, VS your base dead key. This is a very simple explanation.

Well i like it. If you guys like it. It has the delay i read about for SSB. Will 100 watts draw much attention from Uncle Charlie? This is a mobile unit, i do have a 12v power supply but do they make a base model?

i see it is available on Amazon, but it isn’t the pretty blue one i have seen on searches. This amazon search is from the Nederlands.

"pretty blue one"? That's funny. I have several carpenter hammers with different colored handles and I can hammer nails in with all of them. Lol....lol...lol!

My radio is fresh back from a President service center for a check up/ tune. I have a new SWR meter. The 12v power supplies Saw had similar specs as my relic, which still puts out 13-something volts. Thank you.

The Service Center set the RF Power @ only 2 watts? What meter are you using to verify the 2 watts?

Shop said it was only putting out two watts and I have an Astatic multimeter that keyed at 2, that’s it, just two... He said This radio was not known for power and that’s all he could squeak out. I am looking for a local radio shop in the WASHINGTON DC area. Can’t find one near me.

Which model number Astatic meter?

This is interesting. The shop could only "squeeze-out" two- watts. What was the wattage prior to the two-watts? There could be other issues.

I swear I do not know. I was at the mercy of the President Electronics repair facility at Exit42 Electronics in Troutman, NC. I have NO IDEA what’s what. I am not a radio tech so whatever I pay for is taken on faith. I sent my radio in and got it back, have no idea. Frustrating…..though, tonight, i called out to a central florida station and they came back to me. This was very reassuring although the contact lasted for 10 seconds, enough for me to hear my call sign repeated back to me!

Astatic (302-PDC2) . It sure beat my macrodanta meter that said i was puting out six watts on the ancient mary side. The shop said two watts, and two watts is what it read.​

Finding an AC to DC regulated 12v 10A+ power supply is daunting. They are either too expensive, located outside the US or complicated with multiple readouts and so on. Where do you guys shop for a 12v power supply to power said linear?

Take a look at the BTECH RPS-30PRO.

The Astatic 302-PDC2 will not indicate PEP. If you are going to enter the amplifier field, you should have a meter which can measure / indicate actual PEP or else you will be "winging-it" and that can and will be costly.

Whichever power supply he decides to buy, I recommend one with variable voltage. I have never exceeded 13.8 volts and most of the time I use 12 to 13 volts.
