Note
The Orion II is a refinement of the original Orion and introduces several enhancements. Featuring a high-brightness TFT color display, a refined roofing filter system, and advanced audio routing. The radio utilizes a sophisticated architecture with dual 32-bit floating-point DSP processors and a 32-bit control processor to provide high-speed response and superior signal processing.
Basic Features
Dual Receive Capability: Includes an amateur-band-only main receiver (10–160m) and a general coverage sub-receiver (up to 30 MHz) that can operate simultaneously with no performance compromise.
Advanced Roofing Filter System: The main receiver supports up to seven crystal roofing filters; four are standard (20, 6, 2.4, and 1 kHz), with three additional optional narrow filters available.
Customizable AGC: Users can program independent threshold, hang, and decay rates for each receiver, offering over one million possible combinations.
Real-Time Spectrum Display: A continuous real-time display allows for monitoring band activity with five selectable sweep ranges.
Panoramic Stereo (PS): A unique feature that allows operators to hear signals in a spatial stereo field when using headphones, moving from one side to the other as they tune across the band.
High Stability: All local oscillators are locked to a 1 PPM master TCXO, ensuring frequency stability across a 0–50°C temperature range.
Digital Integration: Features Flash-ROM updatability via a serial port and direct PC sound card connections for digital modes like PSK31 without needing an external interface.
