This includes set and for- get controls such as VOX and CW sidetone. Control capability has been added to satisfy ope

25、rator preferences even if your preference is in the minor- ity. Frequency selection priorities (band switching vs. discreet frequency entry) are operator selectable. CW transmit offset is adjustable and includes auto- matic sidetone frequency tracking. All operator options are explained in detail in

26、 Chapter 3. The factory settings or default values will allow you to get started. You can customize operation to niore closely fit your preferences as you become more familiar with the trans- ceiver. BEFORE YOU POWER UP The first time you power up the OMNI VI we strongly suggest a MASTER RE- SET of

27、the microprocessor as explained in Section 2-4.3. When power is first applied, you will observe noticeable frequency drift for 1- 2 minutes as the internal oven comes up to temperature. If the power supply is left on, no drift will occur. See Section 1-8.7 2-2 INITIAL FRONT PANEL SET- TINGS: RF . Fu

If full clockwise control results in less than 100 watts, switch METER to collector current (Ic) and set to 20 amps. or less. Check re- flected power with SWR position on meter switch. A SWR of 2:1 (10% of fo

32、rward power) or less is recommended. 2-3.2 SSB OPERATION Select either LSB or USB. Key mike PTT button and, while speaking into the mike, adjust MIC control so that the ALC LED blinks on voice peaks. Tune to a SSB signal. Adjust the PBT if there is bothersome interference on the receive signal. You

33、are now ready to operate SSB, full transceive, simplex. To fine tune the receive frequency without changing the transmit frequency, turn RIT on and use the RIT/XIT contr,ol. To quickly return the receiver to the exact transmit fre- quency, turn RIT off or hold RIT button in for 1 second. See Chapter

34、 3, Section 1.11, for VOX operation and adjust- ments. 2-3.3 CW OPERATION Select CW mode. When your cw key is closed you are transmitting. With key open you are in receive, simplex. The built-in elec- tronic keyer is adjusted with the front panel KEYER SPEED control. If you do notwantfast break-in C

35、W, switch QSK to SLOW. See Chapter 3, Section 3- 1.15, for KEYER weighting and Section 3-5.14 for QSK-SLOW delay adjust- ments. The rear panel PTT jack can also be used for CW transmit control. If narrow filters have been installed, select the one of your choice and then adjust PBT for best results.

36、 See SSB paragraph above for RIT operation. ; l 2-2 2-3.4 FM OPERATION Select FM mode. (NOTE: This mode currently authorized for use from 29.0 to 29.7 MHz only). Adjust squelch (SQL) for receiver quieting when no signal is present. Press mike PTT switch to trans- mit. In this mode, MIC gain is conve

37、rted to a FM deviation control. Set MIC gain to 12:00 when using a TEN-TEC mike. You may find a slightly higher or lower setting is needed with other micro- phones. The narrow I-F filters and PBT are not active in the FM mode. There are repeaters in use with split input and out- put frequencies. To

38、set up for these, select VFO B, (using A/B button), and tune to the transmit frequency. Select VFO A and tune to the receive frequency. Press SPLIT. Split frequency pairs can be stored in any of the 100 memories. (See Chapter 3, Sections 3-2.2 and 3-3). To return to simplex operation, turn SPLIT off

39、. 2-3.5 OTHER MODES such as the digital modes and A TV, see Chapter 3 and the manuals supplied with the acces- sory equipment. 2-4.1 A FEW WORDS ON MICRO- PROCESSORS On rare occasions you may find the transceiver will not accept commands from the keypad properly or it is operating in an erratic mann

40、er. Spikes or surges on the power supply line or an unforeseen set of circum- stances may confuse the microprocessor. This technology has improved dramati- cally in recent years but it is still pos- sible to have an occasional lockup. If turning POWER off and on does not re- solve problem, the micro

41、processor must be reset using one of the following meth- ods. Part No. 74229 3rd Printing 9/9 Printed in U.S.A Downloaded by RadioManuai.EU P tl.l n = t!l!j to-1 n - 00 Ul - .

44、nal coupler for forward power and SWR detection, and diode switched receive antenna circuits. Six band lines from the BPF/Front End board enter at connector 14 where they pass through rf chokes L6 -L 11 and energize relays K2-K13. These band lines also exit at connec- tor 8, where they are routed th

45、rough the TX Audio board to the 25-pin connector on the rear panel ofthe OMNI VI. Only one ofthe six lines is high at any one time based on the operating frequency of the transceiver. The 100 Watt RF output ofthe PApasses through one of the selected low pass filters and then through the contacts of

46、relay K 1, which is energized by T voltage. The output power then proceeds through the primary ofthe SWR bridge transformer T 1 to the rear panel antenna connector. Bridgetransformer Tl and associ- ated circuitry discriminate between forward and reflected power to develop drive voltages at connector 12 forthe ALC andRF metering circuits on the 9 l1Hz Mixer/IF board. On receive, Kl is open and R voltage is either applied to R24 or R25 through connec- tor 7. The front panel mounted ANT
