Since the beginning of 1965, VEF-Radio Radiol ('' VEF-Radio-65 '') was produced by the Riga Electrotechnical Plant "VEF".
The radiola consists of an 8-tube first-class superheterodyne receiver and a 3-speed electro-playing device III-EPU-20 (II-EPU-40).
The radio receiver is designed to receive in the DV, CB, HF and VHF bands; the HF band is divided into two subbands.
The radio has a smooth tone control for treble and bass.
The radio circuit diagram is similar to the Rigonda-mono radio circuit with the exception of small changes in the denominations of the elements in the KSDV-IF and BP unit and differs in the design of the case, which can be floor-mounted and (or) desktop.
AC consists of a 4GD-4 loudspeaker.
The dimensions of the radio are 740x336x320 mm.
Weight is 21 kg.
Ranges: LW 150 ... 408 kHz, CB 525 ... 1605 kHz, KV-1 3.95 ... 7.4 MHz, KV-2 9.1 ... 12 MHz and VHF 65.8 ..
.73 MHz.
The sensitivity with an external antenna in the ranges of LW, NE, HF is 50 μV, in the VHF range of 5 μV.
Sensitivity with a magnetic antenna in the ranges of LW, SV 1.5 mV / m.
In the AM path, the 465 kHz IF, the bandwidth when attenuating the signal is 6 dB at the narrow band 5 kHz, wide band 11 kHz and local receive 15 kHz.
In the FM path, the inverter is 6.5 MHz, the bandwidth is 150 KHz.
AM path selectivity 60 dB.
The AGC provides a change in the output signal by 11 dB when the input changes by 40 dB.
The maximum output power is 3.5 watts.
The operating frequency range of the AM channel is 80 ... 6000 Hz, the FM channel is 80 ... 12000 Hz, and the recording is 80.10000 Hz.
The EPU is equipped with a circuit breaker and a micro-lift and is designed to play records at speeds of 78, 45 and 33 rpm.
Power consumption when receiving 60 watts, and when listening to a record of 75 watts.
