Stand-by power saving receive is advisable to be used to extend operating time of
the radio from one battery pack without recharging.
While operating on fixed frequencies, voice information is transmitted in:
-F3 analog form, which provides connection of the radio through the link with the
radios of other types, older radio systems in particular;
-F1 digital form. Analog voice is converted into digital form by embedded CVSD-
delta codec. The rate of converted voice information is 16000bps.
In the FHSS mode voice information is transmitted only with conversion into digital
form (CVSD) in the F1 class.
Voice information, converted into digital one, either on fixed frequencies or in the
FHSS mode can be transmitted with technical masking or without it. Technical masking can
also be used during data communications. Technical masking is ensured by the built-in
voice-masking device.
The radio provides radio coverage on medium-cross country while the object,
equipped with the radio, is stopped or on the move, with the range of not less than 4-5 km.
Shorted antenna is intended to enhance the radio operation while providing the
communication over several hundred meters range.
The radio can operate on not more than 16 preprogrammed channels on fixed
frequencies (channels 1 to 16), and on not more than 16 preprogrammed channels in the
FHSS mode (channels 17 to 32). The selection of preprogrammed channel is done, using the
buttons on the front panel.
While operating the radio, it is possible to control it and enter radiodata from the PC,
as well as Radio Data Storage and Entry Unit (fillgun) on the RS-232 interface.
The power supply is provided by the (7.2-7.4) V Battery Pack.
1.2 Technical Specifications
1.2.1Frequency Band and Channel Spacing
a) The radio provides continuous coverage in the 30 MHz to 110 MHz frequency
band;
b) Channel spacing on fixed frequencies is 12,5 kHz.
ATTENTION! While operating the older radios or radios of other type, channel
spacing should be appropriate or not less than 12, 5 kHz.
c) Channel spacing in the FHSS mode is 25 kHz
