BFO inteference signal inteference signal BFO 30 4 RECEIVE AND TRANSMIT D CW pitch control The received CW audio pitch and monitored CW audio pitch can be adjusted to suit your preferences (300 to 900 Hz) without changing the operating frequency. q Enter the keyer set mode. · Push [DISPLAY] once or twice to select M. · Push [MENU] one or more times to select M4. [MENU] CW [F-2] [DISPLAY] Main dial This shows the default setting for the CW pitch control (600 Hz). w Push [MENU] one or more times to select "K3 CW PITCH, " then rotate the main dial to set the desired pitch. e Push [DISPLAY] to exit the keyer set mode. K3 CW PITCH D Electronic CW keyer The IC-703 has an electronic keyer. Both keying speed and weight (the ratio of dot : space : dash) can be set. · Setting the electronic keyer q Enter the keyer set mode. · Push [DISPLAY] once or twice to select M. · Push [MENU] one or more times to select M4. [Y] w Push [MENU] one or more times to select "K4 CW PADDLE, " then rotate the main dial to select the paddle type. · When "ud" is selected, the up/down switches on the microphone can be used as a paddle. [M-CH] [MENU] [F-2] [DISPLAY] Main dial [Z] e Push [MENU] one more time to select item "K5 RATIO, " then rotate the main dial to select the desired weight. · Key weight can be selected from 2. 8 to 4. 5. · Check the selected ratio with the side tone function in CW mode. r Push [DISPLAY] momentarily to return to M4. KEYING WEIGHT EXAMPLE: morse code "K" DOT DASH (Fixed*) DASH Weight setting: 1:1:3 (default) Weight setting: Adjusted Adjustable range SPACE (Fixed*) t Push [DISPLAY] for 1 sec. y Push [MENU] once or twice to select "Q2 KEY SPEED, " then rotate the main dial to select the desired keying speed. · [M-CH] or [Y]/[Z] can also be used to select "Q2 KEY SPEED. " · Keying speed can be selected from 6 to 60 wpm. u Push [DISPLAY] momentarily to return to M4. *SPACE and DOT length can be adjusted with "Q2 KEY SPEED" only. Paddle operation from front panel MIC connector Connect a CW paddle as at right to operate an electronic keyer from the front panel MIC connector. · This function is available from the front panel mic connector only. · Be sure to select item "n, " "r, " "buG" or "oFF" in K4 CW PADDLE in the keyer set mode. 32) · Connect straight key to "DOT" side. 31 CW paddle DOT 3. 9 k ±5% 2. 2 k ±5% front panel MIC connector Eu MIC U/D w DASH RECEIVE AND TRANSMIT 4 D CW side tone function When the transceiver is in the receive condition (and the break-in function is OFF-- below) you can listen to the tone of your CW signal without actually transmitting. This allows you to match your transmit signal exactly to another station's. CW side tone level can be adjusted in the initial set mode (p. 77). D Keyer set mode While M4 is selected in CW mode, push [(F-2)KEY] for 1 sec. to enter the keyer set mode. K1 BK-IN This item sets the CW break-in operation.

The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals. As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations. Below 30 MHz, the recommended limits are specified in terms of V/m or A/m fields as they are likely to fall within the near-field region. [. . . ]
