When the OEM said "discontinued"
Pump-station contactor control cards kept burning out and the manufacturer had stopped making them. Travis Labs reverse-engineered the card, designed a new PCB and firmware, and built a replacement in Lusaka. Deployed since February 2026 — zero failures.

A telecom repair bench in Lusaka
Rectifier modules, site monitoring units and radio units used to leave the country for repair or get scrapped. HCS set up a component-level telecom repair bench: MTN Zambia is a contracted client on a framework repair agreement; Zamtel, IHS Towers and Infratel are in proof-of-concept; MultiChoice has RF amplifiers on the bench.

Broadcast RF power amplifiers on the Lusaka bench
High-end RF power amplifiers from MultiChoice transmitter stations came to the HCS bench in Lusaka. Each unit was opened, worked through with the manufacturer's service manual and checked on the bench with a multimeter and a test rig beside it. HMI panels are part of the same work. This is evaluation repair, not yet a contract.
