Connex CX-46 Turbo N1

The Connex CX-46-TURBO-N1 (also referred to as the CX46TN1) is a high-power 10-meter amateur mobile radio designed for high-output transmit performance, typically delivering 200 to 250+ Watts PEP. It is widely recognized for its “Audio Monster” capabilities and is often used by operators who prioritize strong signal presence and bold audio.
Key Specifications
Power Output: 10/50 Watts AM Carrier; 200 Watts modulation (often reaching 250–300 Watts after professional tuning).
Operating Modes: AM/FM/PA (Public Address).
Frequency Range: 28.015 to 28.585 MHz (standard 10-meter band).
Current Draw: Requires a high-current power source, typically drawing up to 45–50 Amps.
Dimensions: Approximately 7-7/8″ (W) x 11-1/8″ (D) x 3-1/4″ (H).
Technical Features
Internal Amplifier: Features a built-in amplifier section similar to the 98 VHP models, utilizing eight MOSFET transistors for high power.
Audio Controls: Includes a built-in Connex Echo board with dual controls for volume and delay, plus a switchable talkback feature.
Aesthetics: Known for its blue channel and meter lighting, along with a red/green transmit/receive LED indicator.
Noise Management: Equipped with a Noise Blanker (NB) and Automatic Noise Limiter (ANL) to reduce static and interference.
Expandability: Pre-wired for external frequency counters such as the FC 347 or SRA-FC 393.
Installation & Operation Notes
Power Requirements: Due to its high output, it is critical to use heavy-duty power cables (e.g., OFC wire with copper ring terminals) connected directly to the battery with a 50 Amp fuse.
Antenna Matching: A high-quality, properly tuned antenna system is required to handle the 200+ watt output and avoid damage to the radio.
Heat Dissipation: The unit features a large, bottom-facing heatsink to manage the significant heat generated during high-power transmission.
External Speaker: Many users recommend an external speaker, as the internal speaker may be insufficient for clear monitoring of the high-output audio.
