FM transmitter teardown and repair
Fault-finding and restoring a broadcast FM exciter with no service documentation — reconstructing the schematic from the board, then verifying each stage against measurement.

Instrumentation & measurement
Building, repairing, and characterising analogue and RF hardware — and trusting the measurement.
Analogue and RF hardware, from fault-finding to characterisation. A recurring problem is working without documentation: reconstructing a schematic from the board itself, then sweeping each stage to find where behaviour departs from what the topology predicts.
The measurement setup gets as much attention as the circuit. A result you cannot reproduce on a different day, on different equipment, is not yet a result.
