C r To exit the Weather Channel mode, press the CHANNEL selector knob momentarily to return to the VFO mode.
OPERATION Monitor Switch ANL (Automatic Noise Limiter) Feature When listening to a very weak signal from an aircraft or ground station, you may observe the signal disappearing periodically as the incoming signal strength becomes too weak to override the squelch threshold setting. For reduction of impulse noise, such as that produced by an engine’s ignition system, the ANL feature may prove helpful.
OPERATION LOCK Function Beep On/Off The lock function prevents accidental changes to the frequency setting and the keypad controls. The VXA-150’s key/button beeper provides convenient audible feedback whenever a button is pressed. Each key and button has a different beep pitch, and each function has a unique beep combination. r To activate the lock 3 feature, press [F] à [ ( )]. 121.
OPERATION Receive Battery Saver Setup An important feature of the VXA-150 is its Receive Battery Saver, which “puts the radio to sleep” for a time interval, frequently and rapidly “waking it up” to check for activity. If somebody is talking on the channel, the VXA-150 will remain in the “active” mode, then resume its “sleep” cycles.
MEMORY OPERATION The VXA-150 provides 50 user-programmable “Main” memories, labeled “CH - 001” through “CH 050,” and up to 100 pre-programmed memories, des” icon appears ignated “Book” Memories. The “ when “Book” Memory Mode is activated. The Main memories and “Book” Memories can be assigned alpha-numeric names of up to eight characters. Memory System Operation The VXA-150’s Main Memory system allows the user to store, label, and recall channel frequencies which you may want to use frequently.
MEMORY OPERATION When the desired first character appears, press the CHANNEL selector knob momentarily to move on to the next character. r Select succeeding characters in the same manner, pressing the CHANNEL selector knob momentarily after each selection. r After entering the entire name (eight characters maximum), press the [MW (SPL.W)] key for 2 seconds to save all data for the channel and exit.
SCANNING OPERATION The VXA-150 allows you to scan automatically in the VFOø 1 , Main Memory, “Book” Memory, or Weather Channelø2 modes. It pauses on signals encountered, so you can talk to the station(s) on that frequency, if you like. ø1: In the VFO mode, the automatic scanner is only available in the COM band (118.000 - 136.
SCANNING OPERATION Memory Channel-Skip Scanning Continuous-carrier stations like ATIS (Automatic Terminal Information Service) or Weather Broadcast stations inhibit scanner operation. Since these stations are always active, the scanner will be halted repeatedly on their channels. Such channels can be set to be “skipped” during scanning, if you like, so as not to interfere with automatic channel scanning: r Recall the Memory Channel to be skipped during scanning. r Press [F] à [9 (SKIP)].
DUAL WATCH OPERATION The Dual Watch feature automatically checks for activity on a “priority” channelø while you are operating on another channel. During Dual Watch operation, the current channel and the Priority channel will each be polled for a 500 ms interval, as the VXA150 looks for activity on each channel. r To start Dual Watch, press [F] à [SCAN (DW)]. The “DW” icon will appear on the display.
PRIORITY DUAL WATCH OPERATION Similar to Dual Watch operation (described on previous page), Priority Dual Watch is an enhanced version which includes the following additional features: l The receiving time interval (ratio) between the current channel and the Priority channel may be customized via the Menu mode, item PRTM. See page 33 for details. l Irrespective of which channel is currently being received, when the PTT switch is pushed transmission will always occur on the Priority channel.
SPLIT OPERATION The split operation feature allows you to transmit a call to a Flight Service Station using the COM band frequencies, while receiving a NAV band station (such as the ATIS, AWOS etc.).
