00:00:05

I take a small metal box,

00:00:08

open the lid on it, it turns out there are

00:00:11

radio stations in the

00:00:13

battery compartment,

00:00:15

there are no batteries in the radio station,

00:00:17

modern batteries for such

00:00:19

a radio station are, of course, not produced, and

00:00:21

batteries of the same age as these radio stations

00:00:24

have not survived, but I have a standard

00:00:26

complete power supply for mains power,

00:00:30

which is installed in place

00:00:31

batteries battery compartment and

00:00:34

connects to the power block

00:00:37

which, by the way, is

00:00:40

a lamp you ceramic socket remains

00:00:42

to find a 220 volt network but I have it

00:00:45

here in the forest on a tree there was a socket

00:00:48

connected the power the neon light

00:00:51

is on control the supply voltage

00:00:53

shows the norm you can go on air

00:00:56

I will listen broadcast to headphones or

00:01:00

headphones are connected with a regular

00:01:03

two-pin plug, speaking I will have a

00:01:05

carbon microphone located in such a

00:01:08

tube, also connected with a 2-pin

00:01:10

u.k. Well, as an antenna I will have a

00:01:12

small shelf in the

00:01:25

Soviet Union for various

00:01:27

industrial industrial radio communications,

00:01:29

use car and stationary

00:01:30

radio stations granite, who have

00:01:33

radio stations operating in the low

00:01:35

band range from 33 to forty-eight and a half

00:01:38

hertz, they were used on

00:01:40

ambulances, firefighters, and so on In the

00:01:42

70s, these were the predecessors of the

00:01:44

Lena radio stations, which everyone knows,

00:01:46

then already in the eighties there were a lot of them, so it turns

00:01:48

out there

00:01:50

were 2 granite radio stations, in addition to that

00:01:53

lobo Indian car

00:01:56

radio granite there was also a tube

00:01:58

radio station granite shortwave

00:02:01

produced in the early 60s, this

00:02:04

copy was made in

00:02:05

1961 By the way, it still works and the

00:02:08

granite radio station operates in a short

00:02:11

wave range from three and a half

00:02:13

to four megahertz, one might say in the

00:02:15

amateur 80 meter range in

00:02:18

amplitude modulation and in the telegraph

00:02:20

this

00:02:23

radio station does not have any single-sideband modulation, it is made very

00:02:26

simplified and is intended for training

00:02:28

goals, the output power of the transmitter in

00:02:31

amplitude modulation mode is only

00:02:33

0 2 watts in telegraph mode 0 4 watts on the

00:02:36

handset with the microphone there is a button to

00:02:39

turn on the transmission, but it does not switch

00:02:41

this radio station to transmit, to

00:02:44

switch you need to use the

00:02:46

flight switch on the front panel,

00:02:48

which is what I do

00:02:50

base base

00:03:02

heard I

00:03:08

understood you

00:03:13

base reception

00:03:17

and

00:03:21

5

00:03:28

reception

00:03:31

here is such a not very ordinary

00:03:34

radio station it looks not at all like a

00:03:36

military product but like a metal

00:03:39

gray suitcase it’s not clear for what

00:03:43

purposes they are intended but in fact this is a

00:03:45

military training radio station you can say a

00:03:48

radio station from the 60s you yourself agree

00:03:52

Usually a military radio station does not

00:03:54

look like this;

00:03:55

the radio station is completely tube-based; there is

00:03:57

only one semiconductor device; this is a

00:03:59

diode; a detector for the

00:04:02

antenna tuning indicator; everything else is made using

00:04:04

lamps; low-voltage lamps,

00:04:06

battery-powered, with incandescence of 1 and 2

00:04:09

tenths of a volt; and an anode voltage of 100

00:04:11

volts;

00:04:12

powered from the radio station by dry batteries

00:04:16

that were installed in this

00:04:17

battery compartment, respectively, 2

00:04:19

voltages were given out and these

00:04:21

batteries were connected to the terminals here on this

00:04:23

lid there are terminals that were connected

00:04:26

to the battery and 2 anode 2 anode

00:04:29

in series to provide a

00:04:31

voltage of 100 volts, that is, such a

00:04:33

low anode voltage for everything These are

00:04:35

100 volt radio stations and in the receiving mode,

00:04:37

in the transmitting mode, the

00:04:43

power source is connected to the

00:04:46

radio station itself to the receiving transmitter with this

00:04:48

unusual 7-

00:04:50

pin connector, it is made on the basis of a 7-pin

00:04:52

lamp socket, which

00:04:54

are used for finger lamps,

00:04:57

respectively, there are

00:04:58

battery compartment covers on this one a cable with a

00:05:01

connector and there is the same cable on the power supply; the

00:05:06

network power supply produces the same

00:05:10

2 voltages of 12 volts for the incandescent lamp;

00:05:12

100 volts for the anode; it is made on a

00:05:15

power transformer

00:05:17

and 2 rectifiers, which are already made on

00:05:19

semiconductor devices on diodes,

00:05:22

of course there is no stabilization but

00:05:24

there are anti-aliasing filters, this

00:05:26

flat case houses this network

00:05:28

power supply for 6 this year, the

00:05:31

power supply for the lamp in the radio station is quite

00:05:33

small, interesting power plugs

00:05:36

were used at that time, now many

00:05:37

modern people probably have plugs like this and

00:05:39

have never seen the plug on the reverse

00:05:41

side has exactly this the same socket

00:05:43

so that you can turn on another

00:05:45

plug, that is, when we use such plugs, we do

00:05:47

n’t need a tee, we don’t need any kind of

00:05:49

splitter, they can be plugged into one

00:05:51

another as many as you want, and the wire

00:05:53

goes out to the side so that it doesn’t interfere with

00:05:55

turning on the top next plug,

00:05:58

of course it’s very small and now

00:06:00

modern ones are used to all large Euro plugs

00:06:03

with grounding from thicker

00:06:05

contacts themselves, well then in the

00:06:08

60s in the USSR we had, among other things,

00:06:10

these kinds of radio stations, you can say

00:06:13

simplex on and it has separate receivers,

00:06:15

separate transmitters, separate

00:06:18

controls individual settings elements,

00:06:20

but we can still say that it is

00:06:22

assembled according to a transfer circuit, that is,

00:06:24

some of the elements are used both during

00:06:25

reception and transmission; this

00:06:27

low-frequency amplifier is made from two

00:06:29

two-stage Vinci lamps; it works as a

00:06:31

microphone amplifier modulator when

00:06:34

transmitting in amplitude modulation;

00:06:37

this is generally performed radio station with 11

00:06:40

lamps lamps of

00:06:41

these finger series, that is, ordinary non

00:06:44

-rod ordinary lamps with a

00:06:47

filament voltage of 12 volts,

00:06:50

setting the frequency smoothly using a

00:06:52

variable capacitor separately,

00:06:54

setting the receiver frequency

00:06:56

separately, setting the

00:06:58

transmitter frequency, transmitter 3 in cascade,

00:07:01

except for the amplitude modulator, this is a

00:07:02

master oscillator with a

00:07:05

buffer cascade tunable by the circuit and a

00:07:08

power amplifier, the power amplifier was made on

00:07:10

two legs 2 p2p lamp model is this: these

00:07:14

two lamps are rash in parallel since the

00:07:15

anode voltage is very small, only

00:07:17

100 volts, and even with two

00:07:19

lamps connected in parallel, the power

00:07:20

is obtained in telegraph mode in the

00:07:22

carrier 04 here The receiver is a

00:07:25

superheterodyne radio station with one

00:07:26

frequency conversion of almost exactly 465

00:07:30

kilohertz, as was customary at that time in the

00:07:31

Soviet Union in household receivers, and the

00:07:34

receiver circuit is as follows: 1 to 2

00:07:36

mixer with a combined local oscillator, two

00:07:39

stages of an amplifier and with a resonant load in the

00:07:42

anode, a detector and a two-stage amplifier and

00:07:45

interesting This is how the

00:07:47

radio station switches from receiving to

00:07:49

transmitting and back, there are no relays, there is no

00:07:51

switching in the radio station, there is nothing

00:07:54

using the PTT button on the handset, you

00:07:56

can’t switch reception to transmitting, it

00:07:57

works either to receive or to transmit,

00:08:00

what is there, you can really say

00:08:01

simplex outfits remain and happen

00:08:02

This mode is using a ballet

00:08:04

switch on the front panel with

00:08:06

three positions in the middle position everything is turned

00:08:08

off in the right position

00:08:10

the radio station works only for reception in the

00:08:13

left position it only works for

00:08:15

transmissions but our control level is

00:08:17

located this way, that is, in the left position

00:08:19

we turn on the dial transmitter on the left we have

00:08:21

there is an element for setting the transmitter

00:08:24

to clear, if we turn on the right reception, then on

00:08:26

the right we have an element for setting the receiver

00:08:28

to the frequency, here we have a knob for adjusting the

00:08:31

volume of the receiver

00:08:32

[music]

00:09:46

here

00:10:04

we read this is a radio station for working with

00:10:07

two types of antenne this is a whip

00:10:09

antenna of the waders type and is connected

00:10:11

to this connector and an antenna in the form of a short

00:10:14

piece of wire a few meters that

00:10:16

is connected to a terminal on the front panel

00:10:18

since the radio station is a very low-

00:10:20

power amplitude modulation force of 0 2

00:10:22

watts on short waves at the Toris frequency

00:10:25

plan with of course the communication range is very

00:10:27

small and the communication given is only needed

00:10:29

to use radio stations

00:10:31

for educational purposes and when working with a whip

00:10:33

antenna on a whip antenna with movie

00:10:35

glitches, this is literally one two

00:10:37

kilometers when working in telegraph

00:10:38

mode and on an antenna in the form of a beam

00:10:41

several meters long, of course the

00:10:43

communication range increases noticeably

00:10:44

several times, but it’s still small

00:10:46

like you We already saw at the beginning of the video that

00:10:49

the headphones are connected using a regular

00:10:51

plug like this on the front panel

00:10:54

with the letter t, that is, phones and a microphone

00:10:57

are also connected using the same

00:10:58

plug of a standard microphone. I don’t have a

00:11:01

tube like this from some other

00:11:03

radio station, also with carbon microphone,

00:11:05

that is, the input of this radio station, the input of the

00:11:07

apple hard modulator is designed to

00:11:09

connect a carbon microphone;

00:11:11

at the input, a transformer is installed through

00:11:14

which power is supplied to the carbon

00:11:16

microphone, and

00:11:18

low-frequency voltage is removed from the secondary winding; it is supplied

00:11:19

to the lamp grid; the tip

00:11:22

for tuning the antenna to resonance is

00:11:25

such a control element.

00:11:27

called tuning, this is a

00:11:29

variable capacitor that tunes into

00:11:31

resonance the anode circuit of the output stage of

00:11:34

the transmitter

00:11:36

using such a face with three

00:11:39

positions, such keys are usually

00:11:41

used in various

00:11:42

control panels in the remote control for loud-speaking

00:11:44

communications in switches, but here such a

00:11:46

key is used to switch the

00:11:48

telegraph operating mode If the phone is in the

00:11:51

middle position, apparently it is not used in any way in

00:11:53

telegraph mode,

00:11:55

another additional

00:11:56

cascade is turned on in the receivers - this is a telegraph local oscillator

00:11:58

and a telegraph key is connected and in

00:12:02

telephone mode, accordingly, the

00:12:03

amplitude modulation mode is turned on; the

00:12:06

telegraph local oscillator in the receiver

00:12:07

is turned off and in the transmitter an

00:12:10

amplitude modulator is connected

00:12:12

on the front panel of the radio station

00:12:14

one pointer device which in the

00:12:15

initial position shows the

00:12:17

filament voltage of the radio station, that is, 1 and 2 volts

00:12:20

on the same device in the corner instead of one

00:12:22

screw there is a button if we press it

00:12:25

will show we already have the anode voltage

00:12:27

multiplied by 100 thousand eggs is 100 volts

00:12:30

also this the device can serve as an

00:12:32

antenna tuning indicator in order for

00:12:34

it to work as a

00:12:36

tuning indicator on the front panel there is a

00:12:39

separate small button and by pressing it

00:12:43

we see,

00:12:46

roughly speaking, the voltage on the antenna;

00:12:49

accordingly, using the antenna tuning knob

00:12:51

we can adjust the maximum of this voltage the

00:12:53

output stage of

00:12:55

the radio station transmitter is designed to work with with

00:12:58

short antennas, even an

00:13:00

antenna several meters long is connected to the best terminal,

00:13:02

so by connecting such a short

00:13:04

beam literally two and a half meters

00:13:07

long, I can already configure it using

00:13:09

this setting element. As you can see

00:13:12

now, I have radio stations turned on in

00:13:13

telephone mode, that is, amplitude

00:13:15

modulation, so it emits carrier

00:13:17

and you can tune the antenna if I

00:13:19

now switch the radio station to

00:13:21

telegraph mode, then it no longer emits a carrier

00:13:23

and it can often work in telegraph

00:13:26

mode to connect the key there are 2,

00:13:28

respectively, we have terminals or rather one two-

00:13:31

pin socket on the front

00:13:33

panel and the radio has a built-in

00:13:35

key it connects This

00:13:37

plug is written for radio, that is,

00:13:40

this plug is from household subscriber

00:13:42

loudspeakers and by connecting it to the vessel, we

00:13:45

can open the lid on the case here,

00:13:48

on which

00:13:51

we have a miniature telegraph key, and

00:13:53

with the help of it we can already transmit the frequency to the telegraph

00:14:03

[applause]

00:14:14

not very stable, to put it mildly,

00:14:17

tons of telegraph floats very strongly, but

00:14:20

firstly, and before the station it is quite old,

00:14:22

it was

00:14:24

made in 1961 and contains

00:14:26

components from

00:14:28

1959, for example, I think that

00:14:30

most of the elements, of course,

00:14:32

retained their parameters, it works

00:14:34

fine now, but some components

00:14:35

could with over time, it will leak a little, so to

00:14:38

speak, instead of such a miniature

00:14:40

built-in key, of course, to this

00:14:42

connector, to this socket, you can connect an

00:14:44

ordinary full-size telegraph key

00:14:46

with the help of which it works much

00:14:47

more conveniently, of course, a radio station, then the

00:14:50

design in all its parameters is

00:14:52

very unusual and it is made in a

00:14:54

metal case that is not at all

00:14:57

similar to the housings of all other

00:14:58

radio stations of that time, not even to

00:15:01

mention the more modern one, it was made

00:15:03

quite thinly and painted with

00:15:05

paint, it is clear that with such a low

00:15:07

power and such short antennas, the mid

00:15:10

radio station could

00:15:11

really only be used as a training one, only

00:15:13

for very short distances it was possible

00:15:15

with the help It’s worth noting that I have a

00:15:17

smooth tuning, this is, of course, the norm

00:15:20

for that time and it is clear that the

00:15:23

person who used

00:15:25

the radio station

00:15:27

tuned his receiver according to the correspondent’s signal,

00:15:29

that is, approximately on the scale you can see what the

00:15:31

current frequency is 37 or 38 megahertz and

00:15:34

somewhere nearby, for example 3 and 8 megahertz

00:15:37

and we have an operating frequency at the same time and by ear

00:15:40

a person could tune the receiver, but how

00:15:42

he set up the transmitter is not very

00:15:43

clear since there is no mode and self-control

00:15:46

using your own receiver it is

00:15:49

impossible to set the transmitter frequency, that is,

00:15:51

in order to accurately set the

00:15:52

transmitter frequency you still need one friend

00:15:54

another radio station some other

00:15:56

device with the help of which we

00:15:58

listened to the signal of your own transmitters

00:16:00

and set the frequency with the help, otherwise we

00:16:02

can only at a very very rough

00:16:04

risk set the frequency of the transmitter and

00:16:07

our correspondent will be forced to

00:16:08

look for us on the air because it is

00:16:10

impossible to know the exact value the scale

00:16:13

here is very rough, but the radio stations

00:16:14

for training, I think for educational purposes,

00:16:16

these are the tasks whose tasks were needed so that people

00:16:19

could tune in to each other and

00:16:20

learn how to find a signal on the air with

00:16:23

such an inaccurate frequency setting, so

00:16:25

this is the design now to

00:16:28

use such a radio station, of course there is

00:16:30

no point and for educational purposes there is no point, since a

00:16:32

person who learns how to work on

00:16:36

it will not be able to apply these skills anywhere,

00:16:37

since in work in the service he

00:16:40

will in any case be provided with

00:16:41

other radio stations with completely different

00:16:43

controls and for

00:16:45

amateur purposes it too not very

00:16:47

suitable because, firstly, there is no

00:16:48

single-sideband modulation; secondly, there are

00:16:51

separate tuning elements for the receiver

00:16:53

and transmitter, which is very inconvenient;

00:16:55

thirdly, for the telegraph, as you heard, the tone is

00:16:57

very unstable, you need to

00:16:59

do something about it, but what if you change it to the

00:17:01

hooligan range of 3 megahertz and there

00:17:04

they work in amplitude modulation, then

00:17:06

such a power as 0 2 watts is probably

00:17:08

not needed there either, and you need to make a separate

00:17:11

large amplifier that will be

00:17:12

much more complex in complexity than for the

00:17:15

sake of it,

00:17:16

so on the one hand there is nothing

00:17:18

special in this radio station and it’s

00:17:21

already time to use it almost

00:17:23

impossible, but on the other hand,

00:17:26

the radio station is very rare, I saw

00:17:29

quite a lot of different Soviet

00:17:31

radio allied equipment of those years, both

00:17:33

civil and military, for the sake of

00:17:36

communication equipment, I know one way or another,

00:17:38

but I have never seen one like this before the station,

00:17:40

and from the word of the radio station, granite, I can

00:17:43

only imagine that same

00:17:44

low band automotive granite, narrow or

00:17:46

modern borders that are already

00:17:48

microprocessor-controlled, made not in the

00:17:51

Soviet Union, but in Russia, which

00:17:53

no one has with that old granite of ours,

00:17:55

but it turns out there was an account like this from a

00:17:56

radio station, granite is completely

00:17:58

short-wave lamps with amplitude modulation

00:18:01

and for educational purposes using

00:18:04

such a connector in the form of a lamp socket

00:18:07

to connect a power source is,

00:18:09

of course, in my opinion, not a very good

00:18:11

solution. The pins on this connector can

00:18:14

bend the memory very easily, either

00:18:16

because we did not carefully

00:18:18

insert this plug into the socket correctly or

00:18:21

simply because of some careless

00:18:22

storage somewhere in the case and the 4s were damaged,

00:18:25

but what is very pleasing is that this

00:18:27

radio station had

00:18:30

its power supply included as standard, since

00:18:32

batteries now of course cannot be

00:18:34

found like that, but even at that time batteries were

00:18:37

quite an expensive thing and for what -for

00:18:39

educational purposes for the educational process, if

00:18:42

this process took place somewhere in the classroom,

00:18:44

then of course it would be much more correct to

00:18:46

use a power supply, here it is and

00:18:48

it is very small,

00:18:49

not

00:18:51

some separate huge box made directly to the dimensions of the battery compartment, so

00:18:53

in this regard the designers tried,

00:19:18

such a carbon microphone was

00:19:21

very popular at that time, since the

00:19:22

level of the low-frequency signal at the

00:19:24

output of such a microphone is much greater

00:19:26

than that of dynamic or condenser

00:19:28

microphones, tens or hundreds of

00:19:30

times more, and this made it possible to use a

00:19:31

microphone amplifier with a much lower

00:19:34

gain if the input This

00:19:36

radio station was designed to

00:19:37

connect a dynamic microphone, then

00:19:39

you would have to use another

00:19:41

tube cascade, another tube in

00:19:43

the modulators as a microphone

00:19:45

amplifier, the radio station is very interesting in its own way

00:19:47

and at one time in the

00:19:49

sixties it had some

00:19:51

use other than for its

00:19:53

intended purpose probably no

00:19:54

one needed such a radio station, let

00:19:56

alone for what time, especially but on the

00:19:59

other hand, it is very rare and

00:20:01

before in the past I have never

00:20:03

come across such a radio station. It was interesting to

00:20:05

study this radio station now and

00:20:07

tell you about it, thank you for

00:20:09

watching this video use

00:20:12

radio communications of radio stations not only for

00:20:14

amateurism but also for useful

00:20:16

purposes for transmitting information in everyday life at

00:20:19
