SOV - R-873 (Rádiový přijímač KV)

Radio receiver R-873

Radio receiver R-873 allows you to receive "open and clandestine" signals
in the band of short waves.

Frequency range 1.5 to 29,999 MHz is divided into 6 podrozsahů:
Also. 1,5 - 2,999 MHz
II. 3,0 - 4,999 MHz
III. A 5.0 - 7,999 MHz
IV. 8,0 - 12,999 MHz
In. 13,0 - 19,999 MHz
VI. 20,0 - 29,999 MHz

The assembly consists of 5 blocks with the fact that the receiver is in blocks 1 and 2

- Block 3 (power):
It contains a rectifier to power the receiver from a network 220/127 V, 50 Hz, constant voltage stabilizer, voltage converter, for power supply mains voltage DC 26 IN.

- Power source:
a) from the batteries ± (10,6 - 12,6 In) capacity of at least 30 Ah
b) From the network (AC) with a voltage of 127 V ± 10% or 220v ± 10%, with a frequency of 50 Hz;
c) single-pole DC supply voltage + 26 V ± 15%.

- Power receivers :
a) from the batteries 30 W;
b) of the AC mains 100 VA
c) from the source of unipolar DC 80 W


- Dimensions: (width x height x depth - mm)
Blocks 1 + 2 (Receiver): 538 x 462 x 501
Block 3 (Power) : 216 x 201 x 386
Block of 4 : 65 x 45 x 80
Block 5 : 180 x 183 x 210

- The weight of the ensemble : 73,3 kg (55 x 13,5 + 0,3 + 4,5)
