TENTEC TT 565 Orion

TT 565 Orion Hf Trx
The Ten-Tec ORION represents an entirely new concept in high performance HF transceivers. Our goal with this new ground breaking design is to deliver the finest performance level to date from an amateur transceiver.



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 accommodates 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, regardless of filtering system, does this.
