After procrastinating for a very long time I finally summoned up the ‘whatever it was I needed to summon up’ to get a move on with the Minima transceiver. I planned on tackling the digital board first as it seemed logical. It did however need me to solder an Si570 onto the board without any solder paste. So it was going to be a bit of a struggle.
The method I chose was to put a healthy load of flux on the pads and a blob on both of the ends. Align the chip then solder one end, applying a small amount of pressure onto the chip. Then the other end, then back to the first and then to the second again. Making sure I had seated it correctly. after that the other pads seemed dead easy.
The result was that it worked (I think). Although I am unsure as to why is does stay on a single frequency. This will need a bit of looking at. Here’s a very brief video.
