Hello Ken WB2ART,

That Pocket Tutor looks great! I'm glad to hear that you were able to
fix the small mistakes made while building it. Is the speaker an SMD
component?

Hi guys.
I finished the Pocket Tutor this morning.
The Pocket Tutor software works great.

I did make a change to the defaults.
Changed the default code speed to 21, the default call to my call and usepaddles=true.

The build went well, with not too many mistakes.
I did end up installing the volume control where the encoder should be.
A quick vacuum desoldering and that was corrected.
I also installed the speaker upside down. That was also desoldered and corrected.

I would suggest reading Bruce's soldering smd pdf, on his website.

I was not at all familiar with the mcu or audio amp chips. I had to refer to the
pcb picture in PocketTutor6.pdf, to see how the chips lined up.

I did make an annotated picture of the pcb, with the proper orientations of the chips and speaker.
I will put a copy in the files section when I'm satisfied with it.

I'd be happy to answer any questions, if I can, on my build.
