Manpack VHF radio R-005U

The VHF manpack 5 W radio is designed to provide radio communication in stationary and field conditions with direct transfer by personnel, and also as an exciter in other radio.
The radio provides the ability to transmit and receive voice information and data (digital information) when operating at fixed frequencies (not antijamming mode) and in antijamming  mode.
Antijamming mode of operation is intended to ensure the possibility of radio communication in the conditions of setting intentional interference. Protection against intentional interference is provided by the use of a mode with a pseudo-random frequency tuning. The frequency tuning rate is 312.5 times per second. In frequency hopping, a radio provides the ability to work with radio of the same type or with other radio that are compatible with it according to the information exchange protocol in the common frequency bands.
When operating at fixed frequencies, radio communication with the radio of the old park is ensured.

The radio provides the ability to work in the following modes:

– simplex (receiving and transmitting on one frequency when operating at fixed frequencies or receiving and transmitting on one set over the radio channel in frequency hopping mode)
– half duplex (reception on one frequency, and transmission on another frequency when operating at fixed frequencies, or reception on one set over the radio channel, and transmission on another set to the radio channel in frequency hopping)
– another economical radio reception;
– the introduction of radio data.

At fixed frequencies and in the frequency hopping radio station provides the ability to transmit and receive:

– voice information from a handset or from a telephone headset;
– digital information with speeds: (1200, 2400, 4800, 9600, 16000) bit / s from PC or from other devices via RS-232 interface;
– short alphanumeric messages;
– individual (selective), circular (group) and tonal call.

The next economical method is recommended to be used to increase the operating time of the radio station from one battery without additional battery charging.

At fixed frequencies, language information is transmitted:

– in analogue form in the class of radiation F3, provides a combination of a radio station over the radio channel with radio stations of other types, in particular the old park;
– with the conversion of speech information into digital form using the built-in delta codec (CVSD) in the emission class F1. The transfer rate of the converted voice information is 16000 bps.
In frequency hopping, voice information is transmitted only with digitization (CVSD) in the emission class F1.

Speech information, converted to digital form, both at fixed frequencies and in frequency hopping, can be transmitted with or without technical masking. Technical masking can also be applied during data transfer. Technical masking is provided by a speech masking device built into the radio station.
The radio, which is located on the object, provides a range of radio communication in a mid-terrain area in the parking lot and when the object is moving when working on an antenna with a circular pattern, at least 8 – 10 km.
The radio station has the opportunity to work on no more than 16 pre-programmed channels for operation at fixed frequencies (from first to sixteenth), and no more than on 16 pre-programmed channels in frequency hopping (seventeenth to thirty-second). The choice of the programmed channel is carried out by buttons from the front panel, from the remote control, and also from the PC.

When working with a radio station, it is possible to control and enter radio data from devices and equipment, namely:

– from PC via RS-232 interface;
– from the storage device and the introduction of radio data on the RS-232 interface;
– from the remote control (RC) via RS-232 interface;
Note – the remote control – is an integral part of the radio VHF mobile 30 watts.

The radio is powered from the battery with a rated voltage of 24 V.
