Key Features and Specifications
The Connex CX33HPC1 is an AM/FM radio that operates in the 10-meter amateur band (approx. 28.765 to 29.205 MHz). It is a popular choice for truckers and amateur radio enthusiasts due to its performance in a small footprint.

Audio Controls: It includes an integrated echo board with dual controls (volume and delay), and variable talkback, allowing operators to tailor their transmit audio.
Design: The radio has a compact form factor, sharing the exact same dimensions as a Cobra 29 LTD, which makes it ideal for installation in tight spaces like semi-truck cubbies.
Display/Indicators: It features a large, easy-to-read illuminated meter for signal strength and power output, a blue LED channel display, and a red/green LED to indicate transmit status.
Noise Reduction: To improve reception in noisy environments, it includes a switchable Noise Blanker (NB) and Automatic Noise Limiter (ANL).
Connectivity: The radio has a front-panel microphone jack and rear jacks for an external speaker, PA speaker, and an external frequency counter.

Performance: The radio is considered a reliable, “nice, clean radio” that offers a good balance of size, audio control, and output capability.
