Marshal Horn	ea1fb29d39	Nearly done with layout ... To do: - Route Encoder lines - Stitching vias - Replace BNC connector with SMA connector - Fix board outline (for audio jacks)	2020-08-25 10:08:41 -07:00
Marshal Horn	b72cc2972f	v2.0.2 ... Added op-amp buffer to receiver, increased capacitor values Simplified over-voltage protection on analog inputs Modified RX switch to prevent turn-on during transmission Changed RX impedance to 50 ohms Added more buttons and encoders	2020-08-24 10:33:59 -07:00
Marshal Horn	1b499411dd	Fixed netlist issue ... 3.3v was connected to GND due to mis-wiring of the schmitt trigger	2020-08-18 12:26:58 -07:00
Marshal Horn	cc3ed9cfad	v2.0.1 ... Fixed part designation on op-amps. Replaced tl072 with lm4562 for simpler BOM. Added LED indicators on MCU Added RTC crystal, moved DIT and DAH to port B. Added thermistor to measure PA temperature Changed low-pass in PA to 5th-order elliptic Reduced capacitance of C406 due to mosfet drain capacitance	2020-08-18 07:30:19 -07:00
Marshal Horn	6fc16fbfcd	Updated schematic title blocks	2020-08-17 15:30:37 -07:00
