About Me
Hello, and thanks for visiting my QRZ page. My name is Joseph Vaughn, amateur radio callsign KF8ECP.
I am an HVAC/R service technician and Master Certified CFESA technician specializing in:
- Commercial refrigeration systems
- Electrical diagnostics
- Complex controls and automation
- Commercial kitchen equipment
- Advanced troubleshooting
- Systems integration
- Linux infrastructure and field systems
My RF interests evolved naturally from electrical systems, networking, Linux infrastructure, digital radio, emergency communications, and mobile field operations.
I enjoy building practical systems that actually get used: repeater tools, RF resources, mobile HF setups, digital infrastructure, and community radio resources.
Amateur Radio
My current focus areas include:
- HF mobile operation from service vehicles
- Portable and emergency communications
- DMR / digital voice experimentation
- Repeater systems and RF coverage mapping
- Mobile antenna design and deployment
- Balun and unun construction
- Digital infrastructure and Linux-hosted services
I enjoy combining practical field experience with RF systems, creating infrastructure that is useful, reliable, and operationally focused.
