Pearce Simpson AM810 CB Radio

[Shock]

Picked up one of these, so now I'm officially a HAM right? Just kidding .
Kinda cute actually, anyone have the schematics, manual or service manual etc?

What would be the best way to test the output without a proper antenna, swr or commercially made load? Hesitant to fire it up without a load on the output. Have an oscilloscope but just want a rough idea. As far as I'm aware it's been working anyway.

Looks really simple and easily maintained inside, the outside is actually ultra clean and just a bit dusty. Even came with the bracket and a whip base but no antenna.

Looks pretty tidy apart from the dust.
Member defpom has had a lot to do with CB rigs, check out his YT channel on the repairs he does on them.
Fairly sure he doesn't connect an antenna until he needs to check receive/transmit.

BTW if you can grab his attention he'll probably recognize the layout and point you to manuals.

Thanks I dropped him a message.

It's probably only a cheap $199 job. Looks like I'm the first person inside, not really vintage material but could well be apocalypse proof.

The radio doesn’t ring a bell, that is a pretty old unit, I will have to check my files to see if I have anything on it.

You could poke around my website RadioMods.co.nz to see if you find anything, I collected information for many years!

I'm thinking 1988 from the test sticker at the back (I put the cover back on). Says Hatadi Electronics Sydney Australia.

Obviously not "vintage vintage" if you know what I mean, no bank of crystals means it's PLL right? I think they were more on 20 Channel units anyway.

What can you recommend when firing it up and testing? I don't have much in the way of RF, or a radio test set or anything like that. Can I rig up a temporary antenna and approximate the tuned length?

I was probably about 1988 the last time I actually saw a CB heheh.

As long as you don’t transmit you can use anything as a test antenna, it just won’t be optimal and won’t work well, but if you are going to tx then you need a proper tuned antenna or dummy load to avoid blowing the rf final transistor.
