Travis Labs · R&D lab and service centre
Repair. Redesign. Reuse.
The service and design division of HCS. Bring us the drive, rectifier, radio unit or card that the OEM will not support — we diagnose it, repair it, and if it cannot be repaired we design a replacement.
Telecom power & radio repair
Rectifiers, site monitoring units, RRUs, BBUs and RF amplifiers repaired to component level in Lusaka — instead of shipped abroad or scrapped.

Diagnose first. Report always.
- Component-level diagnosis with oscilloscopes, thermal imaging, power-quality meters and meggers — on our bench or at your site.
- Every job logged on our own O'Sense Workshop system: intake, fault codes, photos, QA test and a report you can file.
- Fixed quotation before work starts; framework agreements with published fee schedules for repeat clients.
- Discontinued card? We capture the schematic, redesign with current parts and build a drop-in replacement.
