I had several LM386 amp kits that I bought for a dollar each from China on ebay, so I made one up and added it to the xmitter, per fifties build.

I have to say that the ability to control the amplitude of the input is a plus. When I used my PC to feed the transmitter I had the volume at 100%. Now I can make it 33%, 50% or whatever and just turn the knob on the amp.

Here I'm transmitting "Whipping Post" from the PC to a radio in the other room.
I'm still waiting on the stereo jack, which the post office has sent by Pony Express and won't arrive for another 5 days, so I still only have half a channel.


I made a label for the cigar box.

If I ever make another cigar box project I'll make the label first. I spent more time on the label than I did on the transmitter, and it still isn't perfect.

By the way, cigar stores sell cigar boxes. I got this one for two bucks. You would not believe the variety of boxes, and the craftsmanship that goes into them is outstanding.

Still waiting on mcoates to check in. I didn't mean to hijack the thread but it was his question and fifties answer that got me motivated.

Too bad, as we have a full dial in southern California. It is fun to also pick-up stations such as AM660 in Window Rock, AZ in the evenings.

Great job! And that label threw me for a loop, until I read that you had made it up yourself, looks very professional!

Thx for the tip on Cigar boxes, I'll have to check that out locally.

As for our question about the old summing network being left in or not, I shorted the 1K resistors and didn't notice any difference.
