[. . . ] To readjust the gain, press and hold [PTT] then press [ ]/[ ] to select a more sensitive gain level. The transceiver will remain in Adjustment Mode for approximately 5 seconds. SELECTING AN OUTPUT POWER It is a good idea to select lower transmit power if communications is still reliable. When operating from battery power, you will enjoy more operating time before a recharge is necessary. Press [F], [MENU] to select high (H), low (L), or economic low (EL) power. · You can program different power settings for bands A and B. Note: When the transceiver overheats because of ambient high temperature or continuous transmission, the protective circuit may function to lower transmit output power. · 2 Adjust the VOX Gain by pressing [ ]/[ ] until the transceiver reliably switches to transmission mode each time you speak while the transceiver is transmitting. From the Menu: 1 Enter Menu mode and access Menu 135. VOX (VOICE-OPERATED TRANSMISSION) VOX eliminates the necessity of manually switching to Transmit mode each time you want to transmit. The transceiver automatically switches to Transmit mode when the VOX circuitry senses that you have begun speaking into the microphone. When you operate the VOX function, you must use an optional Headset; the internal speaker and microphone are too close to each other to be used for the VOX function. To turn the VOX function ON: 1 Enter Menu mode and access Menu 134. 2 Select the desired VOX gain level. VOX Delay Time If the transceiver returns to reception mode too quickly after you stop speaking, the end of your transmission may not be sent. To avoid this, select an appropriate delay time that allows your entire transmission to be sent, before Transmit mode ends. 1 Enter Menu mode and access Menu 136. 2 Set the desired delay time to 250, 500 (default), 750, 1000, 1500, 2000, or 3000 ms. · When VOX is activated, the " " icon, gain level, and delay time will appear on the display. Note: If you press [PTT] while the VOX function is ON, the VOX Delay Time is not reflected to the transmission. If you press [CALL] (if 1750 Hz is programmed) to transmit a 1750 Hz tone, the VOX Delay Time is not reflected. The precision of the determination of the intersecting point relies on the satellites and the data collected. Position Determination Principle The latitude and longitude information required by the GPS receiver does not allow for accurate representation of the unevenness of the Earth's surface. For use with GPS, the current standard that defines the precise shape of the Earth is called WGS-84. By using this standard in conjunction with mapping standards for each country, accurate position plotting on a map can be done. GPS and APRS Position Format Although position can be described in many different formats, such as degrees, degrees and minutes, and degrees, minutes and seconds, the GPS system and APRS have standardized on the degrees and decimal minutes format. Just like it is important to use proper international phonetics when spelling on the air, it is important in APRS as in any communications system to have a default standard for position. All operators should be trained to use the DDD MM. mm format by default in voice communications just like in data formats. Using these standards on the air will prevent communications errors, confusion, repeats, and conversions.

" <GPS satellite information> Sky view · When the Internal GPS receiver is On, the internal Satellite signal-strength bars clock is automatically configured with the time data from the internal GPS receiver. 196. · When determining your position for the first time The sky view shows the satellites you are receiving. The satellite signal-strength bars indicate the strength of each satellite you are receiving. A solid bar indicates that the GPS satellite is ready for use. · When only the frame of the signal-strength bar is displayed, the satellite has not yet been captured. Note: When GPS cannot be received, turn the power ON in a clear environment (Open Sky). [. . . ] The keypad also is available to enter alphanumeric characters in step 2. VFO/ Memory Recall mode switch XIT/ RIT offset frequency increase XIT/ RIT offset frequency decrease In LSB, USB, or CW mode: 10 Hz/ 1 kHz PROGRAMMING A TONE FREQUENCY On receiving a tone from the Commander, the Transporter causes the HF transceiver to enter Transmit mode. On both the Commander and Transporter, access Menu 502 and select the desired, same tone frequency. [] [ ] 1 (FAST) switch In FM or AM mode: 1 kHz/ 10 kHz switch [#] 2 (ENTER) [PTT] 1 In VFO mode: frequency entry ON In Memory Recall mode: channel number entry ON To transmit audio on an HF frequency 2 "FS" appears when you select 1 kHz step (LSB/ USB/ CW) or 10 kHz step (FM/ AM). After pressing [#], press [0] to [9] to enter a frequency or memory channel number. SKY CMD ­ 3 WEATHER ALERT (TH-22EA ONLY) The Weather Alert is available only in the USA and Canada. When activated, this function will check for a received NOAA 1050 Hz tone. [. . . ]
