Charleston Build #3

We will do a group build in the next few weeks in Westminster MD at the
Mason-Dixon hamfest on October 24th. We will bring the PC boards,
parts, solder paste.
First we will have a stencil to put solder paste on the boards.
Second, builders will have magnifying glasses, tweezers etc to place
parts on their boards. The solder paste remains tacky for 8 hours so
the boards will hold the parts in place.
Third, we will bring our toaster oven and thermal controller to reflow
the solder on the boards.
Forth, the builder will use a fine tip soldering iron to place the low
pass filter, transformer and connectors.
Finally, we will bring a test fixture and computer to check out the
board for operation.
We still have several boards from previous builds that we have debugged
so you can pick them up. We also have several Nexsys II boards that
have been paid for and can be picked up.
We are also working on a Ubuntu based receiver software package called
Quisk. Hopefully, we will have install DVDs that will install a full up
operating receiver program on a computer starting from a blank hard
drive. We should have more information as we make progress on this.
If you have magnifiers, stereo microscopes, fine tip soldering irons
bring them along. Also, if you have a computer along the lines of a 2.4
GHz processor we may be able to try installing quisk on it although we
may get overloaded trying to handle this while building boards.
If you want to drop by and just see what it is like, drop by. If you
worked on previous builds come on over and give us a hand with new
builders. Feel free to spread the word to others.
