Professional Digital Licence Free Transceiver
The IC-F4029SDR professional digital licence-free transceiver utilises the latest 6.25kHz ultra narrow digital voice technologies, providing digital clarity, razor sharp signalling performance and a level of secrecy from less congested dedicated digital PMR channels.
DIGITAL PMR 446 FEATURES
The IC-4029SDR utilizes 4FSK/FDMA modulation and 6.25kHz digital narrow channel spacing, which is half the channel spacing of the existing analogue PMR 446 system. This way, the 100kHz band width allocated for digital PMR 446 is efficiently divided into 16 channels, or twice the current analogue voice channel capacity making this product incredibly spectrum efficient.
A Path from analogue PMR 446 to digital PMR 446 in one unit
By changing the channel setting, the IC-F4029SDR can be used on existing analogue PMR 446 channels. This provides users with an upgrade path from analogue PMR 446 to digital PMR 446 in one unit. Being analogue/digital compatible, any businesses or private users currently using analogue PMR446 can begin replacing their analogue radios with IC-F4029SDR and enjoy digital quality as well as relief from congested spectrum.
32 codes of prefixed status messages can be sent and received. 16-character messages and 6 types of alert beeps sound that for call reception, are programmable for each message.
“Common ID” group code
This function is similar to an analogue CTCSS/DTCS code. By setting 1–254 common ID codes, the IC-F4029SDR opens its squelch only when a matched code is received. It provides quiet stand-by and group call functions while sharing a channel with several groups. The code “255” is the fixed code for an all stations call.
Security of digital voice
‘Eavesdropping’ by current scanner receivers is impossible at this stage. Since there are no other competing radios, initial users will have a high level of security in digital voice communication mode.
