Review BENDIX KING 155 Tso Nav/comm Transceiver Glideslope 28v P/n fits KX

The **Bendix/King KX 155 TSO NAV/COMM Transceiver (Part Number 069-1024-R20)** is a high-performance, dual-mode aviation radio designed to deliver unparalleled reliability and precision for both VHF communications and VOR/LOC navigation in modern general aviation aircraft. Engineered under strict TSO (Transportation Safety Obligation) certification, this transceiver combines cutting-edge technology with rugged durability to meet the demands of demanding flight operations, from cross-country trips to complex IFR approaches. Powered by a 28-volt DC system, the KX 155 integrates seamlessly with modern avionics suites, offering a streamlined interface for pilots to manage critical radio functions with intuitive clarity. Its advanced NAV/COMM architecture allows for simultaneous operation of two independent VHF channels one for communication and one for navigation eliminating the need for manual channel switching and reducing cognitive workload during critical phases of flight. The transceiver features a robust **Glideslope receiver**, enabling pilots to receive and decode ILS (Instrument Landing System) glideslope signals with exceptional accuracy, enhancing precision during final approach and landing. With a frequency range spanning from 108.00 to 137.00 MHz, the KX 155 supports all standard aviation frequencies, including VOR, LOC, and COM channels, while its **DME (Distance Measuring Equipment) compatibility** further enhances situational awareness by providing precise distance information to navigational aids. Built to withstand the rigors of aviation environments, the KX 155 is constructed with high-quality materials, including corrosion-resistant components and a sealed, weatherproof enclosure, ensuring long-term reliability even in harsh conditions. Its **backlit LCD display** provides clear, adjustable text and symbols, reducing pilot fatigue during night operations or in low-light conditions. Additionally, the transceiver incorporates **fail-safe features**, such as automatic frequency retention and emergency power backup, to mitigate potential system failures and maintain critical communication links. Whether installed in a light aircraft, business jet, or complex multi-engine platform, the Bendix/King KX 155 stands as a testament to aviation innovation, offering a perfect blend of performance, versatility, and dependability for pilots who demand the highest standards in their avionics.

### **Bendix/King KX 155 TSO-C129 Nav/Comm Transceiver (P/N 069-1024-R20) Pros and Cons**

#### **Pros:**

1. **TSO-C129 Certification** This unit is certified under TSO-C129, meaning it meets strict aviation safety and performance standards for navigation and communication equipment. This ensures reliability and compatibility with FAA regulations.

2. **Dual-Band VHF Comms (118.00 136.975 MHz)** Supports both standard VHF navigation and communication frequencies, making it versatile for general aviation, flight training, and light aircraft operations.

3. **Glideslope Receiver (ILS Localizer & Glideslope)** The inclusion of a glideslope receiver allows for Instrument Landing System (ILS) approaches, which is critical for precision landings in low-visibility conditions. This is particularly useful for pilots operating in busy airports or adverse weather.

4. **28V Power Compatibility** Works with standard 28V aircraft electrical systems, making it a straightforward replacement for older or failing transceivers without requiring major wiring changes.

5. **Reliability & Brand Reputation** Bendix/King is a well-established manufacturer in aviation electronics, known for durable and dependable equipment. Many pilots and mechanics trust their products for critical avionics.

6. **Backward Compatibility** Designed to work with existing wiring harnesses and mounting brackets, reducing installation complexity and cost.

7. **Lightweight & Compact** The unit is designed to fit within standard avionics bays, making it suitable for aircraft with limited space.

8. **Long-Term Availability** As a widely used model, spare parts and technical support are likely to remain available for years, reducing long-term maintenance concerns.

---

#### **Cons:** 1. **Age of the Model** The KX 155 is an older design (introduced in the late 1990s/early 2000s) and lacks modern features such as:

- **GPS integration** (no built-in GPS navigation).

- **Digital tuning** (manual tuning knobs may feel outdated compared to touchscreen or digital interfaces).

- **Wi-Fi or remote programming** capabilities.

- **Compatibility with newer avionics systems** (e.g., Garmin G3X, Dynon, or other glass cockpits may require additional interfaces).

2. **Limited Software Updates** Unlike newer avionics, this unit does not receive firmware updates, meaning it may not benefit from performance or security improvements over time.

3. **Potential for Obsolescence** While still functional, the lack of modern features may make it less appealing for pilots upgrading to more advanced systems. Some newer aircraft or avionics suites may not integrate as seamlessly.

4. **Higher Long-Term Costs** Without GPS or digital navigation, you may need to purchase additional equipment (e.g., a separate GPS unit) to achieve full modern navigation capabilities. This could increase overall avionics costs.

5. **Manual Failures** Older mechanical components (e.g., tuning knobs, internal relays) may wear out over time, potentially requiring more frequent maintenance or replacement compared to newer digital units.

6. **Limited Diagnostic Tools** Troubleshooting issues may require more manual testing or reliance on older service manuals, which could be less detailed than those for modern avionics.

7. **Resale Value** Older Bendix/King units may depreciate faster than newer models, especially if the aircraft is being upgraded to a glass cockpit or modern avionics suite.

### **Conclusion:**

The **Bendix/King KX 155 (P/N 069-1024-R20)** is a **solid, reliable choice** for pilots who prioritize **ILS glideslope capability, TSO-C129 certification, and simplicity** in a VHF nav/comm transceiver. It is an excellent **budget-friendly option** for aircraft that do not require advanced digital features, such as GPS or touchscreen interfaces. The unit is well-suited for:

- **Flight training** (where ILS practice is valuable).

- **General aviation** (for pilots who rely on traditional analog navigation).

- **Aircraft with limited avionics budgets** (where adding a separate GPS is acceptable).

However, if you are looking for a **modern, integrated avionics solution** with GPS, digital tuning, or compatibility with glass cockpits, newer models (e.g., Garmin GNC 255, Bendix/King KX 165, or KMA 25) may be more advantageous despite a higher upfront cost.

---

### **Recommendation:** - **Buy the KX 155 if:**

- You need a **reliable, certified ILS glideslope receiver** for precision landings.

- Your aircraft lacks advanced avionics, and you are comfortable with **manual tuning and analog navigation**.

- You are operating on a **tight budget** and do not require GPS or digital features.

- You plan to **keep the aircraft for a moderate period** (5 10 years) without major upgrades.

- **Avoid the KX 155 if:**

- You want **GPS integration, digital tuning, or modern avionics features**.

- Your aircraft is being **upgraded to a glass cockpit** (e.g., Garmin G3X, Dynon SkyView), as the KX 155 may not interface well with newer systems.

- You prioritize **long-term flexibility** and are willing to invest in a more future-proof unit.

- You frequently fly in **complex airspace** where GPS-based navigation (e.g., RNAV, WAAS) is advantageous.

#### **Alternatives to Consider:**

- **Bendix/King KMA 25** (if you want a more modern, digital interface with VOR/ILS).

- **Garmin GNC 255** (for GPS VOR/ILS in a single unit).

- **Bendix/King KX 165** (if you need ADS-B and other modern features).

- **Used/Refurbished Garmin GNS 430/530** (if budget allows for a more capable GPS/nav combo).

Ultimately, the KX 155 is a **proven workhorse** for pilots who value **simplicity and reliability** over cutting-edge technology. For those seeking a more integrated or future-proof solution, investing in a newer model may be worth the additional cost.
