Farhan sent me the schematic of the AISAT amateur digital satellite that went into orbit on April 1, 2019 from India. He notes that the circuitry is very simple. Indeed, it reminds me of the very simple but effective circuitry we saw in satellites in the early days of the space age. Beautiful simplicity, with an Arduino on-board. And it is great to see that Farhan did not forget the low pass filter. FB OM.
