Take a look at ORION's primary benefits:

The heart of the ORION design is a pair of 32-bit floating-point ADI SHARC DSP processors. Using dual 32-bit devices provides much more processing "horsepower" than a transceiver using a single 32-bit DSP processor can provide. The result? Absolutely unparalleled HF receiver performance, filtering, and flexibility.

Full dual receive capability. An amateur-bands-only main receiver, (10 through 160 meters) utilizes both crystal and IF-DSP filtering. The sub receiver is IF-DSP and is general coverage from 100 kHz to 30 MHz. Both receivers can be used simultaneously on any frequency, with no compromise in performance. The two receivers can share a single antenna or each can be fed to a separate antenna. Receiver controls are available on both receivers. Bandwidth, AGC, PBT, Hi-Lo Cut, AF and RF Gain, attenuator, DSP NR and notch filtering are all selectable independently on each receiver.

Very high RX intercept points, superior dynamic range and an extremely low phase-noise synthesizer make ORION's main receiver performance unmatched by any other HF transceiver.

590 receive IF-DSP bandwidth filters independently selectable on each of the main and sub receivers (100 Hz - 6000 Hz in 10 Hz steps). The main receiver also accomodates up to six crystal filters in the first I-F stage. Three of the six filters at 6.0, 2.4, and 1 kHz are standard. Optional filters for 1.8 kHz, 500 Hz, and 250 Hz can be added. These filters can be cascaded with any of the 590 selectable IF-DSP filters. The sub receiver has its own set of 590 filters that are selectable independent of the main receiver filtering. Rather than being limited to a single wide roofing filter at 15 or 20 kHz (compromising close-in receiver performance), ORION's selectable crystal filters narrow the roofing bandwidth to as little as 250 Hz to avoid any compromise of close-in receiver performance caused by loud nearby signals. No other transceiver does this.

Programmable AGC response time for both receivers.. Conventional AGC settings of OFF, FAST, MED, and SLOW are provided, but the new programmable mode is groundbreaking. Users may build their own personal AGC characteristic by selecting threshold, hang and decay rates. More than one million possible AGC combinations can be selected in programmable AGC mode. Favorite programmed AGC settings can also be saved and instantly recalled by the operator. Each receiver can have its own AGC settings selected regardless of where the other receivers AGC setting is placed.

True diversity reception using both receivers. Both receivers can be simultaneously fed to two separate antennas on the same frequency and controlled using a single VFO tuning knob. Superior low-band DXing capability using two separate receive antennas, on two receivers, and transmitting on a third TX antenna. Three antenna connections are provided: Two SO-239 connectors for transceive or receive antennas, a third via phono connector for RX-only use.

Continuous real-time spectrum display allows monitoring of band activity. Selectable sweep ranges allow user-definable limits to the amount of spectrum being monitored with ORION main receiver.

"Instant Two Radio Mode" allows ORION to instantly QSY between two different bands. Two linear amplifiers, two sets of accessory devices via dual band data outputs and two antennas can optionally be connected to ORION to allow instantaneous QSY (useful for seeking out and working stations on one band during a contest between CQing on a different band, for example).

Virtually indestructable 100-watt PA. Over-voltage protection, current protection for final transistors and thermal shutdown are built-in. Rated 100% duty cycle, 100 watts output, no time limit with added optional model 310 cooling fan.

Superb SSB audio is yours at a touch of the AUDIO button. Audio equalization is provided in both transmit and receive. The transmit response can be adjusted to have more bass or more treble. Separately, receiver audio can be EQed for bass and treble response. 18 selectable SSB transmit bandwidths to a maximum of 3.9 kHz are provided. See figures 3, 4, and 5 below for TX and RX equalizer graphs.

Ten-Tec's new Panoramic Stereo receive feature. Listening with stereo headphones, you can turn PS receive on and hear signals in stereo. As you tune across the band, signals move from one side through center to the other side in your headphones. Better than so-called "binaural" reception, this unique Ten-Tec feature can be used in SSB modes as well as CW. You've got to hear it to believe it! See below for downloads of example .WAV files.

Adjustable rise and decay times for transmitted CW waveform. User adjustable at the touch of a knob from 3 to 10 mS in 1 mS steps for "hard" or "soft" keying according to your taste.

Nine adaptive DSP noise reduction filters let you select the right amount of NR for elimination of broadband hiss, noise, etc., plus DSP automatic notch for auto filtering of interfering carriers in SSB modes. Manual notch filter is also provided with greater than 60 dB of cut and with adjustable width.

Dual noise blankers. Both a traditional-style analog and an IF-DSP noise blanker are provided for suppression of line and other pulse-type EMI.

Heavy duty internal automatic antenna tuner (optional). Ten-Tec's internal auto tuner is no mere load trimmer - from 6 to 800 ohms may be matched (10:1 nominal SWR). Coax fed antennas only.

Voice keyer and CW memory keyer built-in. Program up to three voice messages and up to three CW messages for playback by pressing the SEND1, SEND2, and SEND3 buttons.

"60 METER READY"- the ORION is ready to operate on the new 5 MHz allocation.

"Panic" on-the-fly reset button. Managed to get yourself confused by pushing buttons and turning knobs? Press and hold the RECALL button and the radio resets parameters to factory defaults without changing the mode or frequency of operation or having to turn off the transceiver.

Ten-Tec was first with Flash-ROM update capability with our Pegasus transceiver back in 1998. ORION is also Flash-ROM updatable. To obtain the latest version of the ORION, simply visit our firmware download website at www.rfsquared.com and download the software. Connect ORION to your computer via a serial port cable, and send the software to the radio. It's that easy!
