The world of ham radio is constantly evolving, and at RF.Guru, we’re pushing the boundaries of repeater technology. Our latest project, ON0ORA, is a cutting-edge UHF repeater built using RF.Guru’s high-performance transceiver and receiver modules. Designed for superior reliability, low noise, and impressive sensitivity, this repeater sets a new standard in RF communications.
Why ON0ORA Stands Out
Building a high-quality repeater requires more than just off-the-shelf components. That’s why we engineered ON0ORA with custom-built, high-performance hardware tailored for exceptional RF performance. Here’s what makes this system truly special:
- UHF Transceiver & Receiver Modules – Designed for optimal signal clarity and efficiency.
- Hand-built 70cm Duplexer (118dB Isolation!) – Courtesy of Duplexers.eu (Finland), ensuring top-tier separation.
- RM-Italy UHF Power Amplifier – With additional noise filtering for cleaner transmissions.
- Dual 30A Switch Mode Power Supply – Engineered for ultra-low noise & ripple.
- RF.Guru Router – Featuring WiFi, 5G, and WAN capabilities with minimal RFI.
This build is all about performance, durability, and efficiency, ensuring crystal-clear signals with minimal interference.
Measuring UHF RX Sensitivity: The Results Speak for Themselves
One of the key performance indicators of any repeater is its receiver sensitivity. Using SVXSpot & SINAD 12dB, we measured an impressive -120 dBm on our receiver module—proving just how well it performs in real-world conditions.
