Making outline
- Populate discrete transistor analog IF amplifiers, filters, gain switching and two readout channels
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Readout/passive-components/discrete-semiconductors are candidates for constituent reuse; this is receiver-specific assembly."
