Lets Build Somethng

Productive day in the shack.

I tried different paper today for the toner transfer method to make my own boards.  This paper is quite a bit cheaper than the "blue" type.  I've only done 1 board and it seems to work just as well.  Need to do a couple more to make sure.

So I etched another Si5351 booster board, populated it with most of the components.  I received my smt caps yesterday so I put them on the 2 boards.  Modified the board layout to accommodate the pot I'm using so board 3 will represent the better board when I get around to it. Total of 3 boards are required for this project.

I had 6 xtals to use in the crystal filter.  I did some measurements and here are the results:

xtal    value
1      11,072.061
2      11,072.275
3      could not get a reading
4      11,071.969
5      11,072.254
6      11,072.202

Need to acquire several more to get the bet possible match.
