The OMNI-VI
Plus

It took nearly 30 years of highly focused engineering to produce the Omni VI Plus. Our passion is to provide the finest possible performance to meet the demands of even the most serious DXers and contesters. The design platform of this latest OMNI evolved meticulously from 12 previous transceivers, each pushing performance thresholds a little further. Suggestions from present TEN-TEC owners made measurable contributions to this product. Take a look and judge for yourself.

YOU CAN'T WORK WHAT YOU CAN'T HEAR

Technology has advanced to the point where most high performance rigs on the market have excellent strong signal handling capability. The real design challenge is to hear weak signals between the strong ones when the band is crowded. The best synthesizers just don't measure up. OMNI VI Plus is unique - it's the only rig with crystal mixing to essentially eliminate this phase noise problem.

Phase noise generated inside the competitor's rig causes the noise floor to temporarily increase, covering weak signals inside your passband, especially when strong signals outside your passband are within a few kHz of where you'd like to listen. The bottom line - hear weak signals under the worst band conditions, signals our competition can't hear!

SELECTIVITY

Superior selectivity eliminates interference from even the closest signals. Achieved by cascading optional filters from both I-Fs. Provides up to 4 choices of bandwidth in the 6.3 Mhz I-F and 3 choices in the 9 Mhz I-F, close to the antenna where they belong. That's 20 - 24 poles of filtering! Two of the 7 filters are standard, add only the options that fit your personal operating. All filters can be selected independent of mode.

THE POWER OF DSP

DSP technology provides amazing benefits for both SSB and CW. OMNI VI Plus includes single button DSP NOISE REDUCTION. A 5 to 15 db reduction of broadband noise is typical - makes signals leap out of the noise. DSP AUTO NOTCH instantly eliminates interfering carriers - now work 40 meters day or night. DSP LOW PASS provides 5 choices to cut the highs "just the way you want" to reduce listening fatigue. Rig even remembers your separate choices for SSB and CW. The DSP processor also generates the CW transmit offset, adjustable 400 - 990 Hz, with auto tracking sidetone. This is audio level DSP at its very best.

QUALITY CONTROL....BACKED BY LEGENDARY SERVICE

Rigorous computer-controlled tests exercise every OMNI. Made possible by the rigs high speed PC interface coupled to automatic test equipment. Our own custom software runs the entire process. There's also an overnight burn-in. Each rig transmits into a dummy load, cycling bands along the way. One final performance check by experienced hams finishes up the test. Reliability out of the box and for years to come - backed by our legendary TEN-TEC service.

AS MUCH COMPUTER AS TRANSCEIVER

Powerful microprocessor delivers the latest digital features. Changing frequency has never been easier with direct keypad entry, single button band change and band stacking registers.

Lightning fast QSK for CW and AMTOR and adjustable delay on SLOW QSK. Look at this lineup of other digital features: dual VFOs, +/-10 Khz RIT/XIT, full time clock, iambic keyer, 100 memories, and scratch pad. Four ways to use memories are provided: Memory Scroll, Memory Tune, Channel Scan, and Band Scan.

"SPORT" PC interface (Serial Port Operation of Receive and Transmit) is an enhanced high speed interface. It runs up to 19200 baud for minimum "wait" time under PC control. Two choices of output ports are provided. Compatible with most major software.

EVERY OMNI IS UNIQUE

Sixteen different features can be set to suit your personal operating style. Three short menus for easy access. Factory presets get you on the air immediately, so you can customize at your leisure. See the highlights below:

• Select favorite tuning rate for MAIN tuning and another for RIT, one set for SSB and another for CW!

• Choose your priority - Direct keypad entry or single button band select

• Clock - Full time or on demand

• Display Intensities - 16 levels

• Audio Keypad Annunciator - ON or OFF

• PC Interface Speed - 1200 to 19200 baud

• Keyer - type A or B

• Front Panel Control of VOX, sidetone, keyer speed and weight

THE FINAL TOUCHES

Front panel layout is meant to use not just admire; 100% duty cycle final is so rugged it doesn't require SWR foldback; Main tuning knob is die cast aluminum coupled to a high resolution encoder for a smooth feel with adjustable torque; Each band crystal is phase locked to oven-stabilized time base for frequency stability.
