A42 Portable NOAA Analog Radio

The A42 is designed to fit in the palm of your hand with an elegant and smart design that is somewhat unique for a business radio. It combines user-friendly operability with a new front panel layout, 6 programmable keys and an easy-to-read, dot matrix screen display for simple operation.

¡ª Highlights ¡ª

¡¡

128*64 LCD Display ¡¡ 3 Programming Keys
¡¡ An LCD screen allows users to view channels, call up stored information and navigate through the radio¡¯s features. ¡¡ ¡¡ You can program or assign to perform a user specific function. Personalize the required functions for convenient and quick operation.
Signal Strength Indicator ¡¡ Power On Message
¡¡ The Signal Strength Indicator measures the amount of power present in a radio signal. It is an approximate value for signal strength received on an antenna. ¡¡ ¡¡ Personalized text or picture logo will be displayed when the power is turned on to better identify the user.
Channel Alias ¡¡ Monitor
¡¡ Allows the user to give each channel a user defined name. ¡¡ ¡¡ This feature allows you to check if a channel is clear before you transmit.
Scan ¡¡ Priority Scanning
¡¡ The channel scan feature enables a two way radio to continuously scan each channel for activity. ¡¡ ¡¡ During the scanning process, the set priority channel is scanned first.
Hands-free VOX ¡¡ Power Adjustable
¡¡ This hands-free feature allows you to get on with other manual tasks while you stay in touch with other users. ¡¡ ¡¡ This feature allows you to switch between high and low power modes on the radio.
Wide/Narrow Band ¡¡ Key Lockout
¡¡ Narrowband takes up less frequency space and lowers the chance for interference, wideband channels can carry more infos but require more power. ¡¡ ¡¡ When activated this feature allows the user to lock the buttons so that in case the user presses them by mistake, it does not result in some unwanted action.
Battery Saver ¡¡ Busy Channel Lockout
¡¡ The radio will switch to automatically after being left unused for a certain amount of time, lessens the drain on your battery and makes it last longer. ¡¡ ¡¡ This feature keeps communication lines open by preventing radios from listening or transmitting through conversations outside their talkgroup.
Time-out Timer ¡¡ Compandor
¡¡ This feature will stop the transmission of the two-way radio if the radio is transmitting for a long duration. ¡¡ ¡¡ This feature can help improve signal-to-noise ratio, reduce the background noise and obtain good audio quality at the receiver.
Scrambler ¡¡ Eavesdrop Reducer
¡¡ A technology is used to scramble communications to prevent other radio users in the vicinity from listening to your conversations. ¡¡ ¡¡ A scramble code that makes your transmissions sound garbled to anyone listening.
Squelch Tail Elimination ¡¡ Digital Service
¡¡ Squelch Tail Elimination(STE) is used to eliminate squelch tails by sending a brief low-frequency tone right before a transmission ends. ¡¡ ¡¡ Using the digital service feature, the radio alias display function can be realized, and the target radio can display the name of the call originator
PTT ID ¡¡ Private Call/Group Call/All Call
¡¡ This feature allows the radio to transmit and/or receive a radio ID and lets you know who is transmitting to you. ¡¡ ¡¡ Private Call allows a radio user to place a call to just one user, Group Call provides voice call service in a group.
Stun/Kill/Revive ¡¡ Frequency Hopping
¡¡ Stun and Kill disables a radio over the air and Revive restores the disabled radio. ¡¡ ¡¡ Frequency hopping is a method of transmitting radio signals by rapidly switching the carrier between different frequency channels.
Easy Pairing ¡¡ Voice Prompt
¡¡ This radio has a fast frequency measurement and decoding function, easy to talk with other radios. ¡¡ ¡¡ The radio actually talks to you in a human-like voice. You will hear the prompt spoken in plain relative language.
Power-on Tone ¡¡ Low Battery Alert
¡¡ A sound prompt when you turn on the power, which is a very practical function in dark places or for people with visual impairments. ¡¡ ¡¡ This warning reminds that your battery is low and must be either recharged or replaced.
Roger Beep/Talk Confirmation Tone ¡¡ Keypad Tone
¡¡ When this feature is activated, a tone is transmitted to the listener after a transmission. ¡¡ ¡¡ Pressing a single key of keypad produces a sound to remind that you already successfully press this key.
Call Tone ¡¡ NOAA Weather Alerts
¡¡ Call tones allow you to transmit a tone to other radios in your group to alert them that you want to talk. ¡¡ ¡¡ This feature will give you the latest NOAA weather information delivered to your radio real-time.
1750Hz ¡¡ CTCSS/DCS
¡¡ 1750Hz is used to connect to the repeater. ¡¡ ¡¡ CTCSS uses continuous tones below 300 Hz whereas DCS uses digital data and all encoded words can be used on the same channel without interference.
DTMF ¡¡ 2-Tone
¡¡ DTMF is a technology that uses a combination of tones to perform a number of useful signaling operations. ¡¡ ¡¡ This feature employs a sequential transmission of 2 audible tones, enabling the receiver to hear an alert tone.
5-Tone ¡¡ Noise Reduction (Optional Paid Feature)
¡¡ Similar to 2-tone, the 5-Tone is used to enable alerts, alarms, send IDs, and many other functions. ¡¡ ¡¡ Noise reduction is the process of removing noise from a signal, in order to improve background sound quality to be clearer.
Bluetooth (Optional Paid Feature) ¡¡ ¡¡ ¡¡
¡¡ A radio that is Bluetooth Capable supports a wireless Bluetooth® device, such as an audio headset. ¡¡ ¡¡ ¡¡
