New 32-bit control processor using the latest generation Freescale DragonBall Super VZ chip. Provides faster front panel control response and accelerated remote operation via RS-232. This new processor also provides the horsepower for a future planned "HIGH SPEED SWEEP" accessory. Features, price and availability of accessory to be determined.
All-new firmware from the ground up. DSP code is refined, crafted and compacted to levels unimaginable even two years ago. Provides faster (stock) sweep with finer resolution, enhanced DSP automatic notch and DSP noise reduction.
All-new suite of ORION II-specific roofing filters is arranged in one, single bank to allow user to select the absolute ideal roofing filter for mode, band conditions, and personal preference. The narrow (600 and 300 Hz) filters are now located in the same initial bank with all the rest. This new arrangement yields subtle improvement in dynamic range and the new filters have less passband ripple than any we've ever offered. ORION II comes standard with 20, 6, 2.4, and 1 kHz installed. Optional filters are 1.8 kHz (model 2000), 600 Hz (model 2001), 300 Hz (model 2002).
Mixing architecture for the analog stages has been rearranged to provide self-correction for frequency stability.
Digital mode operators will appreciate variable (programmable) line level output on rear panel completely independent of front panel controls.
ORION II now uses the popular 8 pin mic connector. This broadens the range of mikes and accessories readily available through the hobby for your use without finding or making adaptors.
OPTIMAL USES OF ORION RECEIVER FOR WEAK SIGNAL DXING AND CONTESTING
Take a look at ORION's primary benefits:
Dual 32-bit floating point ADI SHARC DSP processors
Full dual receive capability
Very high RX intercept points.
590 receive IF-DSP bandwidth filters independently selectable on each of the main and sub receivers
Adjustable receiver filter shape factors
Programmable AGC response time for main receiver
True diversity reception using both receivers
Continuous real time spectrum display allows monitoring of band activity
"Instant Two Radio Mode" allows ORION to instantly QSY between two different bands
Virtually indestructable 100-watt PA.
Superb SSB audio is yours at a touch of the AUDIO button
Ten-Tec's new Panoramic Stereo receive feature.
Adjustable rise and decay times for transmitted CW waveform
Nine adaptive DSP noise reduction filters
Dual noise blankers
Voice keyer and CW memory keyer built in.
Flash ROM updatable
TX bandwidth: 100-3900 Hz in 10-Hz steps.
TX frequency response: 50-3900 Hz max -6 dB points, adjustable.
TX equalizer: Up to 6 dB/octave bass/treble boost/cut.
TX speech monitor: Audio taken after filtering, processing.
Crystal roofing filters are used in the Orion for one purpose only – to prevent signals from outside the target passband from compromising the high dynamic range and third order intercept point of the receiver. They are not for setting the final passband. Traditionally, transceivers have used a 15 to 20 kHz roofing filter at the front end of the receiver chain – and any signal appearing inside that roofing filter would allow compromise of close-in receiver performance even if that signal did not appear in the receiver’s passband of 2.4 kHz, or 500 Hz, or whatever the operator was using for a bandpass filter. Here is a key point: if there is no offending signal, narrower roofing filters gain nothing for RX performance over the wider values – and in the case of the 250 Hz crystal roofing filter, could slightly inhibit readability on the very weakest signals.

The Heil PR40 Proline Broadcast Mic features the new technology of the Heil DM 6 dynamic element with response down to 28 Hz. and stays perfectly flat up through 18kHz. with a beautiful mid range rise giving this new microphone gorgeous vocal articulation. It truly outperforms many of the current microphones that all use at least 30 year old technology. Gorgeous craftsmanship, high quality components and a beautiful champagne luster finish with the most articulate, natural sound from a dynamic, the PR 40 will soon become the sound industry standard.
In many blind A/B tests in a Burbank rehearsal hall, the Heil lab, and several major studios around the U.S., this revolutionary Heil dynamic microphone exhibits amazingly clear, clean, natural sound that equals and surpasses many of the cheap condenser models that have recently flooded the U.S. market. The Heil PR40 uses a very unique copper wound voice coil with a neodymium magnet structure which creates a magnetic field ten times stronger than the traditional magnets of other microphones. Coupling to a low mass quilted aluminum diaphragm exhibits the tremendous low frequency response and low distortion throughout it's wide frequency range.
The dynamic Heil PR40 looks like, feels like and acts like a condenser in every respect. No more phantom power. No more background noise and you now have the absolute quietest microphone - ever. It truly outperforms the old industry standards costing 5 to 6 times more.
NOTE:
This mic was designed principally for studio and broadcast use. It may also be used for traditional amateur radio applications with the addition of the appropriate XLR cable and HS 2 handswitch or the FS 2 footswitch.
