PLR2

NBFM Multichannel Data Packet Link Receiver

Frequency:173.200 - 173.325MHz (UK); 150.825 - 152.450MHz (AUS); 433.875 - 434.650MHz (EU); 458.525 - 459.1MHz (UK)

The PL modules use the hardware of the existing LMT/LMR transmitter receiver pair, combined with completely new firmware to produce a simple to use but readily controllable data link.
Inexperienced users of ISM band radio modules often require a totally transparent interface. This can require considerable processing power, and buffer memory, to be provided in the radio device.
The more experienced user, on the other hand, may not want to write a raw radio interface, but desires a module that gives more control over the datastream than a 'beginners' solution. The PL radios represent such a compromise solution.
