Description:
LPD hand-held radios are authorized for licence-free voice communications use in most of Europe using analog frequency modulation (FM) as part of short range device regulations, with 25kHz channel spacing, for a total of 69 channels. In some countries, LPD devices may only be used with an integral and non-removable antenna with a maximum legal power output of 10 mW.
Voice communication in the LPD band was introduced to reduce the burden on the eight (now sixteen) PMR446 channels over shorter ranges (less than 1 km).
Feature:
- Dual Band PMR/LPD transceiver, Channels: 16 PMR446 (16 pre-programmed)+ 69 LPD
- Wide LCD display with backlight
- Low battery indicator
- Auto power save: automatic current economy circuit
- 38 CTCSS and 83 DCS tones in TX and RX
- CALL button with 5 tones selectable
- Battery life up to 12 hours
- Fast charger (4h)
- Monitor function
- BAby Sitter function
- Buttons for the channel selection
- Out of range function (automatic or manual)
- SCAN function
- Keypad lock
- Hi/low power selection (PMR band)
- Roger Beep on/off
- VOX for hands-free communications with 9 selectable levels
- USB port to recharge the radio
LPD433 (low power device 433 MHz) is a UHF band in which license free communication devices are allowed to operate in some regions. The frequencies correspond with the ITU region 1 ISM band of 433.050 MHz to 434.790 MHz
