Mystery parts 1. Dave Curtis’ Schematic Rev3. John Diaz’ Schematic. These L3,L4 (L3,L8 in original) are hand wound coils that need to be specially made here at SSL. Mystery part 2. Where do we order this oscillator? The answer is “Dorothy Knows”. Other questions! .

Other questions! • Caps 10-32 not found in 1206 package, what is comparable? Ans: Tantalum Caps will never be found in that package, find another. • Resistors listed as RWR81 (R41,19,21,44,49) – how do we translate that into a package size? Answer: RWR81 is a milspec package, look for commercial part possibly in 2815 package. • 2 caps 0.01 pF @ 50V. 10 pF @ 10V, can’t find those anywhere in Digikey or other cat. Answer: 0.01 pF @ 50V is a misprint in the new schematic, should be 0.01 microF. The other one does not have to be 10V it can be 100 and that can probably be found.
Curtis Diaz Problem Diaz Schematic is missing “Antenna_Deploy_Control” input
Curtis Diaz Problem Resistor values do not match
Diaz Problem Wire is not connected
Curtis Diaz Problem Multiple Discrepancies
Curtis Problem Diaz Voltages do not match on 47uF resistors
Diaz Curtis Problem Capacitors do not match
Curtis Diaz Problem Capacitor Values do not match
Curtis Diaz Problem Percentage on resistor absent in Diaz Schematic
Curtis Diaz Problem Percentage on resistor absent in Diaz Schematic, also not connected to 64 pin?
Curtis Diaz Problem Resistors do not match
Problem Need 8v HERE!! Where is the Input voltage on pin 4 of U25 in the Diptrace schematic?
Question Why is the pull up resistor connected to On/Off toggle instead of Vin or missing on some of the FPF2106 load switches in both schematics?
