Main channel RX (broadband):16 switchable frequencies in either of following ranges:- VHF (150 ÷ 250 MHz) – RBK 300-VU- UHF (470 ÷ 880 MHZ) – RBK 300-UU
Talk-back channel TX (narrowband):16 switchable frequencies in following range:- UHF (400 ÷ 520 MHz) (It is necessary to keep the minimum distance from TX)
True diversity receiving system.
Full modular architecture allows to build customized units.
Very easy and friendly to operate.
Optional switching device (remote-controlled by PTT push-button on the Portable Unit) allowing the reporter to remote-switch the stationary receiver AF output-line between "main" and the auxiliary "intercom" output.
Wisycom exclusive digital sub-carrier technology prevent any degrading of the modulation quality or reduction pf the audio bandwidth for the features:- remote TX battery monitoring- tone-squelch (or "intercom" PTT) operating
Easy PC frequency-reprogramming by the user (in the pre-set switching-window).
Rapid factory frequency re-allocation (in the whole working range).
Exceptional sturdiness and absolute reliability
The most advanced RF and AF technologies assures the maximum connecting security even with weak and interfered signals.
