I got my hands on an unknown version of the RF10, marked as RF10 SK on the content card. The parameters remained as for the classic RF10 but the tuning was changed, "mechanical programming" stops were added and the layout of the controls was changed.

P.S Does anyone know anything more about it?

Technical note on RF10 (Tact 1) and related resp. previous fastener.

At the beginning of the 60's, obsolete domestic shortwave radios RO21 (Liben), RM31 (Supertana) were replaced, as well as A7b (RO22) and RF11 (Petr) manufactured in our Soviet license in the 50's - [Czechoslovak concept inspired by German Kl.Fu.Spr.d (Dorette)], new radios of the R105-R114 series and later R105d-R114d under the designation Astra. The direct replacement for RF11 was the RF12 radio station (Sava), not RF10 (Tact 1).


For many reasons, Astra radios were used until the 1990s, when they were excavated and replaced by more modern designs.


With the span of the turn of the 70's and 80's, the new modern concept of the RF10 radio station (Tact 1) was to be the first replacement for the obsolete Czechoslovak Astra radio stations. However, due to the complexity and high production cost, the introduction of this radio into active service was problematic and appeared only in "selected" units. (PS, RSS, PVOS, LM, etc.) It was produced in several versions until the mid-1980s. The whole system excelled with a huge number of accessories such as a complete car installation, charging cabinets, voice sets, a set of antennas for various types of connections and distances and an expanding device for motion detection in depth surveying, etc.


In the second half of the 90s, the RF10 was replaced by a new digitized radio station or. communication set RF13 (Radmila).

Own notes from dad's memories, OK1SP, 5th PLO/5th PLDP - Protection of the headquarters of the 1st Tank Division, Slany, VU 2478.


Note OM3CU: RF11 is not a copy of Dorette, it is just a recurring rumor. When thoroughly comparing the scheme and design, it is clear that only the power, microphone and headphone connector, the concept of a separate source box and the method of switching reception are common. Electrically, the construction of the Soviet RSB is much closer. RF10 was also included in the CO, radio stations Astra simply lived to where they could be transported.

...and rozsirujici device for motion detection in hloubkoveho already...
I nesúhlasiť,the system PS-ZOT from pôvodnej RF-10 used the iba batteries,ovládacie gombíky and metal packaging.Electrical circuits and other príslušenstvo boli are totally different and so sets the RF-10 are totally nekompaktibilné,worked months on rovnakých frekvenciách,but digital signals from the PS-ZOT zachytené on the RF-10 are well to ničomu,like, so embarrassing voice transmission..

Power supply/battery charger, nf amplifier, allows remote control of the radio via cable (using cabinet B), TP-25 connection (and transmit/receive via TP-25), intercom between cabinet A and B, transmit/receive via cabinet B, speakerphone, and data transmission.
This was typically used in vehicles and to control the radio from the driver's cab (via cabinet B)

There were even more lockers:
A-the one described above
B-remote control and intercom to cabinet A
C-power supply block from 24V for cabinet A
D-battery charger
E-network power supply to D or A
F-voltage filter


Then there was the data box, I have that one in my collection, ele in a desolate state, when I get to it one day, and generate it, I'll post pics.
The 40W terminal amplifier to the antenna was made only as a prototype, because it interfered with the TV signal.
I also have some knowledge of the voice concealer, the box was soldered between the handset and the radio.
Then the radio station was still used with the S-BON set to wirelessly fire charges for the deep reconnaissance units.
And finally as a remote control for a remotely operated target trainer- a small aircraft (but I don't know the type). This was plugged in instead of a handset.

The amplifier was made only in a few prototype pieces, I don't know where they ended up. Anyway, it was never mass-produced, because allegedly its power and harmonic emission interfered quite significantly with TV reception.
The concealer ibe inverted the frequency spectrum of spoken speech, so it didn't conceal it that much (and nowadays it's not a problem to decipher it at all), but in any case it didn't allow eavesdropping on "random" and curious persons. It plugged in between the handset and the radio, a small box with a rotary switch, a cable and a jack for a microphone. It takes power directly from the radio station via the handset connector.2 pieces were needed for communication, the box also "unhooked" the handset. But for communication with other subscribers without this device, it had to be switched off each time, because again the normal received speech was thrown off. According to the owner's info it was made experimentally sometime in the 90's. Unfortunately its detailed documentation has not been possible for me to this day.
I have the data unit tucked away somewhere or misplaced, unfortunately it was in a pretty dismal condition and is awaiting rediscovery and refurbishment.
Possibly it is also photographed in one of the prescriptions for this radio.

Hey. Hey,


I'm trying to put together a complete RF-10 radio set. Unfortunately, I am looking in vain for a connecting cable (19-pin) between the RF-10 and the A box. If there is someone who could spare one of these cables, I would be delighted.


Thanks,


Peter

If I may ask, what is an "A box"?

Hi, could I get some more information about the 40w amplifier and the speech concealer, or photos of the data unit??
Thank you very much for the positive treatment
