10、ds of increasingly intense competition in DXing and contesting, while adding many non-performance related features that the active ham can also appreciate. OMNI-VII offers superb reception and transmission of CW, SSB, digital modes, FM, and AM on all 10 HF amateur bands and 50 MHz. UNPACKING OMNI-VI

11、I Examine OMNI-VII for signs of shipping damage. Should any damage be apparent, notify the delivering carrier immediately, stating the full extent of the damage. Retain all damaged cartons. Liability for shipping damage rests with the carrier. We recommend that you keep the carton and fillers in the

12、 event that storage, moving, or shipment becomes necessary. The hardware and accessories listed in Figure 1-1 come standard with your OMNI- VII. Make sure that you have not overlooked anything. ABOUT THIS MANUAL The OMNI-VII is a firmware updateable transceiver. Features and functions on the transce

16、tered and regulated DC voltage. The supply voltage can range from +12.8 to +15.0 Vdc but +13.8 Vdc is the optimum value. The voltage source must be capable of supplying minimum 23 amperes continuous duty. We recommend using the included DC power cable (P/N 86095). We have also included spare connect

17、or pins (P/N 41020) and a spare 2 pin power connector shell (P/N 35165) for building your own cable. The power supply plug will attach in only one direction to the polarized two-pin DC connector on the OMNI-VII rear panel. Use no less than #14 gauge (#12 recommended) stranded wires for three-foot lo

18、ng connections to accommodate the required current demand during transmit. Use heavier gauge wire for longer power supply leads. NOTE: always enable the power source first and then the transceiver. If a generator or alternator supplies the dc source, always 588 manualSecond release August 20075 Part

19、 #74409 Printed in USA turn off the transceiver before starting or shutting off the dc source equipment. These recharging devices often generate large voltage spikes that can damage the transceiver. A WORD ABOUT GROUNDING A good ground system is essential for optimum operation of any HF transmitter.

20、 The best solution is to connect all the station equipment chassis together using a heavy gauge of flat ground braid. Use a short length of braid to connect to a ground rod. If you are not using a linear amplifier, a less ideal ground may suffice. A ground connection to a copper cold water pipe was

21、often suitable, but that is now a violation of the National Electrical Code.Be aware that many modern water connections use plastic pipe, and are not suitable ground connections. Antenna type and its proximity to the station are also factors in choosing ground methods. With good resonant antennas lo

22、cated away from the station, the AC ground in your house wiring might be adequate. PHILOSOPHY OF DESIGN Ten-Tecs goal with the OMNI-VII transceiver was to provide an HF transceiver that meets several disparate criteria. 1) Be easy for the average amateur to operate. 2) Have a feature set that experi

23、enced amateurs expect a top of the line piece of equipment to include. 3) Offer Amateur Radios first completely Ethernet controllable HF rig, with an eye to remote operation becoming more and more popular as time passes. 4) Include general coverage HF receive capability plus 50 MHz. The filtering sy

24、stem in the OMNI-VII uses what we refer to as “distributed” roofing filters. The definition of roofing filters varies; in Amateur Radio terms the term has come to mean a crystal or mechanical filter that allows for the preservation of available receiver performance for realistic on-the-air situation

25、s, as opposed to lab conditions when only two signals at a given spacing are present for test purposes. General coverage HF transceivers today are of an upconverting, VHF level first I-F, followed by two or three more conversion stages. This VHF I-F first stage is somewhat problematic due to physics

26、 to create an adequate mode-appropriate roofing filter. At the same time, some amateurs are reluctant to use a ham bands- only HF transceiver that may have a low frequency first I-F and be generally more suited to high performance applications than a general coverage HF rig. The question was how to

27、combine a general coverage receiver with a mode-appropriate system of filtering appropriate for high-end Amateur Radio receiver performance. We refer to the roofing filters in the OMNI-VII as “distributed” because filters are spread across both the first and second I-F stages. The conversion stages

28、in the OMNI-VII are 70 MHz first I-F, 455 kHz second I-F, 14 kHz (DSP) third I-F. A monolithic filter at 20 kHz bandwidth is present at the first I-F stage between the first and second mixers. Selectable second I-F filters at bandwidths of 20, 6, 2.5 kHz, 500 Hz (optional) and 300 Hz (optional) can

29、be cascaded with the first I-F monolithic filter at 20 kHz bandwidth. Bandwidth filtering is done in DSP at the third I-F and is controlled by the BW encoder on the transceiver front panel. The net effect of using 455 kHz second I-F filters is to increase blocking dynamic range over what the receive

30、r would be capable of without the second I-F filters installed. Third order intercept point essentially remains constant. The front-end AGC in the transceiver is after the 455 kHz I-F filters; having them installed prevents the radio from attempting AGC action on a signal that is outside the bandwid

31、th of the 455 kHz I-F filter. SSB operators will not require additional filters; additional filters can be installed optionally by CW or digital mode operators. 50 MHz transceive operation at 100 watts output power is included in the OMNI-VII. Additional receive capability to 48 MHz has been provide

Repeater operation via the SPLIT capability is provided for, as are CTCSS ton

33、es and retaining both of these in the transceiver memories. The remote control capability of the OMNI- VII is unprecedented in Amateur Radio. While remote operation of HF equipment has been done via the Internet or data links for several years prior, OMNI-VII is the first transceiver that allows dir

34、ect connection to a high-speed router via Ethernet without a computer for remote operation. Additionally, we have made available a graphical user interface for controlling the radio remotely, the source code for the GUI, and programming instructions for the transceiver available on our firmware upda

35、te site RADIO STATE VS. REMOTE STATE OMNI-VII operationally at first glance is not much different from other HF transceivers. However, within this product lies the ability to remotely operate it from virtually any high- speed Internet access point. RADIO STATE is what we describe as the “traditional

36、” operation of the OMNI-VII. Turning knobs, pushing buttons just as with any other Amateur Radio transceiver. How the screen looks and the radio operates in RADIO STATE is described in detail in sections 2 through 5 of this manual. RADIO STATE is also used for “local” control of the OMNI-VII with a

37、PC. Local control is connecting the radio directly to a computer via the serial (RS-232) port on the rear panel. The transceiver then can be controlled by the user from the local PC, from the front panel controls, or both. REMOTE STATE is when the transceiver is placed into service as a remote devic

38、e. REMOTE STATE disables transceiver functions from local control and disables some (like VOX operation and the internal CW keyer) altogether. REMOTE STATE also alters the layout of the radio screen to give you a much more utilitarian user interface. The One Plug GUI software to control the radio in

39、 REMOTE STATE is available for free download from our firmware update website .Instructions for the firmware and controlling the radio in REMOTE STATE are also provided there. The default is RADIO STATE. To toggle to REMOTE STATE, turn the transceiver off. Press and hold the 2 button on the band cha

40、nge keypad. Turn power on, continuing to hold the 2 button down. After a few seconds, the REMOTE STATE version of the screen will appear and you can release the button. For the curious: go ahead and have a look. You dont have to have the radio connected to anything or plan to use it in remote mode t

41、o put the radio into REMOTE STATE. To return to RADIO STATE, turn power off, press and hold the 1 button on the band change keypad. Turn power on, continuing to hold the 1 button down. After a few seconds, the RADIO STATE version of the screen will appear and you can release the button. When powered

42、 off in either RADIO STATE or REMOTE STATE, the radio will retain the same STATE setting until changed from the front panel by the user. In case of power failure in REMOTE STATE remote operation, the transceiver will always come back up in REMOTE STATE when power is restored. 588 manualSecond releas

(1) POWER This switch turns t

44、he transceiver power on and off. (2) PHONES This jack uses a ” receptacle for plugging headphones into OMNI-VII. Either stereo or mono headphones may be used, nominal impedance 16 ohms, though phones using an impedance of 8 to 16 ohms load will be useable with the transceiver. Headphones above 16 oh

45、ms (like 32) can be used without damage to the transceiver but audio output to the headphones may be reduced. When headphones are plugged in, a small headphone icon will appear near the top left of the radio screen. (3) KEY The front panel provides a ” stereo jack for connection of a key, external k

46、eyer, or paddles. See Figure 2-1 for proper wiring. OMNI-VII on initial power-up has the internal keyer disabled. To use the internal keyer in a CW mode, press the SP button (SPeed) and then rotate the MULTI knob for an appropriate CW speed (Note: In SSB modes, SP is used for speech processing and d

47、isplays a different value). common Key or dit dah Figure 2-1 Paddle Wiring for Using Internal Keyer 588 manualSecond release August 20078 Part #74409 Printed in USA Pin 3 on the ACC 1 connector on the rear panel also allows you to connect an independent keyer or computer to share CW keying. This wou

48、ld be useful if using the output of a computer program for transmitting CW (like contest logging software) while also desiring a paddle to be connected to the radio for using the internal keyer. Connect the CW keying output of the computer logging program to PTT pin (3) on the ACC 1 jack, and then c

49、onnect your paddle to the front panel KEY jack.See the description of (31) ACC 1 in Section 3 of this manual. (4) MULTI ENCODER The front panel MULTI knob is used for adjusting a variety of transceiver functions. Pushing various buttons on the circumference of the screen enables functions that are then value-adjusted by the MULTI knob. Display letters in green on the transceiver screen indicate the item being adjusted. Example: pressing the PWR button to adjust power changes the green display to read POWER20W turning the MULTI knob adjusts power level up or down. Exa
