range (403...473 MHz) in one hardware and selectable channel spacing. The SRL-35 can offer radio speeds up
to 19.2 kbps and has a selectable serial interface speed between 300 … 38 400 bps.
The SRL-35 includes a built-in LCD display, offering the user both new features and increased flexibility. No
