Manual abstract: user guide YAESU FT-23R
Detailed instructions for use are in the User's Guide.
[. . . ] In order to gain the most enjoyment and operating efficiency from your FT-23R, we recommend that you read this manual in its entirety, and keep it handy for reference as you explore the many capabilities of your new transceiver. Before using your FT-23R, be sure to read and follow the instructions in the "Before You Begin" section of this manual.
GENERAL DESCRIPTION
Congratulations on the purchase of your Yaesu amateur transceiver!Whether this is your first rig, or if Yaesu equipment is already the backbone of your station, rest assured that your transceiver will provide many hours of operating pleasure for years to come. The FT-23R is an elite-class HF transceiver providing exceptional performance both on transmit and receive. [. . . ] The operating mode is selected using the [MODE] buttons to the left of the Main Tuning Dial knob, and the VFO (A or B) to which the selection is applied is selected by the [A] or [B] button above the [MODE] buttons. Usually, the [A] button glows Red, signifying that the Main band (VFO-A) is being adjusted. Similarly, pressing the [B] button will cause its indicator to blink Orange for five seconds, signifying Sub band (VFO-B) adjustment. Therefore, press the [A] or [B] button to select the desired VFO, then press the [LSB] or [USB] button to select one of the SSB modes. For AM operation, press the [AM/ FM] button repeatedly until the imbedded LED glows red. QUICK POINT: By convention, LSB is used in the 7 MHz and lower Amateur bands for SSB communication, and USB is used on the 14 MHz and higher bands (the 10 MHz band is used for CW and data modes only). When the [AM/FM] button glows orange, it indicates that FM operation is engaged. Alternatively, you may use the [UP]/ [DWN] scanning buttons on the MH-31B8 Hand Microphone to sweep up or down the current band. Press the microphone's PTT (Push To Talk) switch to begin transmission; speak into the microphone in a normal voice level. ADVICE: The " " indicator will light up in the frequency display area, confirming that transmission is in progress. When transmitting in the AM mode, rotate the [RF PWR] knob so as to set a maximum (carrier) power output of 25 Watts.
4. The remaining 89 memories are reserved for the 89 most-recent tuning points, for quick frequency change without the need to retune the ATU. The ATU in the FT-23R is designed to match impedances within the range of 16. 5 Ohms to 150 Ohms, corresponding to an SWR of 3:1 or less on the HF amateur bands (6 m amateur band: 25 Ohms to 100 Ohms, corresponding to an SWR of 2:1 or less). Accordingly, simple non-resonant whip antennas, along with random-length wires and the "G5RV" antenna (on most bands) may not be within the impedance matching range of the ATU.
ATU OPERATION
1. Use the Main Tuning Dial knob to set the radio to the desired operating frequency within the Amateur band. Press the [TUNE] button momentarily to place the ATU in the transmit line (no adjustment/tuning will occur yet). QUICK POINT: The momentary press of the [TUNE] button will turn the tuner on, and the microprocessor will automatically select the tuning point closest to the current operating frequency. Press and hold in the [TUNE] button for two seconds to begin automatic tuning. The transmitter will be en" icon will blink while tuning is gaged, and the " in progress. When the optimum tuning point has been reached, the radio will return to receive, and the " " icon will again glow steadily (instead of blinking). While tuning around the band using the Main Tuning Dial knob, you will observe that the " " icon blinks momentarily every 10 kHz. This momentary blinking indicates that a new tuning window has been entered. [. . . ] You may adjust the equalizer gain and Q-factor in this selected audio frequency via menu items "141 tAUd PE3 LVL" and "142 tAUd PE3 BW. "
