Hi
I was looking over the BITX 40 schematic last night before watching Farhan on Tom's W5KUB show. At first, I was a bit confused with the signals flowing back and forth around the two-way amps. I thought I would grab my highlighter pen and mark up the schematic.
But, then I thought maybe others are also confused when first looking at the schematic. So, I made two drawings?in the computer this morning that shows the receive and transmit path. You will find these drawings in my K7AGE directory,
I also included the LibreOffice Draw files. If I have made any mistakes, please let me know. You can also modify the original files if you would like. All open source!
Hope this helps,
Randy, K7AGE
