This device is used to verify the charge level of the battery and the individual cells inside. The voltmeter is simply connected via the connector to the battery terminals. </span><div><span style="font-family: courier;"><br /></span></div><div><span style="font-family: courier;">Immediately after connection, the voltage of the battery pack is measured at no load. After pressing the right load button, the load (bulb) is connected. For new, freshly charged cells, the voltage should not fall below 6.5V when tested with a load. On the left side of the device there are two sockets (+ red and –black) and a load button. These sockets are used to test individual cells inside the battery pack (again, we can measure with or without load). During testing, we connect the supply cables to the individual cells (!). </span></div><div><span style="font-family: courier;"><br /></span></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh85VdYdGuhPKUpzqXkw7pG6LqtjMX1MwMeLF1Y1wLua5QPHDnOKU2vGPBwfRc6f4GNJ5X88j0fmGXCLgbhwIavrPBeec5UzUJrk-zrcHCP6uB6HpZSMqIYALiTqYltVjyiTwfcrBzyX_kimBYoF84O0C-Jij_E1_iBaeOCWGjQfAW7nBmsFRwmakh8/s548/2x-vybijec-zdrojove-skrine-rf-10-95694160.jpeg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="548" data-original-width="411" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh85VdYdGuhPKUpzqXkw7pG6LqtjMX1MwMeLF1Y1wLua5QPHDnOKU2vGPBwfRc6f4GNJ5X88j0fmGXCLgbhwIavrPBeec5UzUJrk-zrcHCP6uB6HpZSMqIYALiTqYltVjyiTwfcrBzyX_kimBYoF84O0C-Jij_E1_iBaeOCWGjQfAW7nBmsFRwmakh8/s320/2x-vybijec-zdrojove-skrine-rf-10-95694160.jpeg" width="240" /></a></div><br /></div><div><span style="font-family: courier;">Max. the input voltage of the voltmeter in this case is 2V.

The discharge therefore takes place until the source box is completely discharged which is dangerous for the cells of course! The discharge current is approximately 800mA.

Box A should mainly perform the following functions: it takes care of powering the radio with a voltage of 6V (it serves as a voltage stabilizer of 6V), it can also serve as an emergency charger for one battery pack with a current of 1 / 10C, NF amplifier for loud interception sessions, if box B is available, the set performs the function of an intercom and in connection with the field telephone TP25 and the device TP25rd it will perform the function of a cordless telephone bridge. </span><div><span style="font-family: courier;"><br /></span></div><div><span style="font-family: courier;">The box is powered by "on-board" voltage from the car battery of the vehicle 12V = or from a bulk car battery, or for continuous operation at home satisfies the mains stabilized power supply 13.8V / 3..5A used and sold for CB radios. The supply voltage is connected to the rear screw terminals marked + - 12V (it is the 1st and 2nd screw terminals counted from the left, looking at the back of the cabinet). The cabinet can withstand an operating voltage in the range of 10 ... 15V =, but above 14V = I would not bother it (due to relatively sensitive light bulbs). The consumption from the battery or mains supply is from 0.6 to 2.4A, depending on which functions are currently switched on on the cabinet. The cabinet is switched on with the toggle switch to position "I" (it is the toggle switch second from the left when looking at the front panel of the cabinet) and switching on is signaled by a lit green light above the switch (second from the left when looking at the front panel). </span></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZjPuC1eZ0ZIBrQTDWpJWshOzaODvTnt3nyahcBSnUCypAXTCb1xj9bT26IJpXvUZccXjC4o-x9F6qTV4Z1K4-NK9zBEljDBaTME3BNOHIUUdvgEI1whoAi6CqZBlF-SwK5qFyrhujoRbE2zz7Fl3FJ-GRHZ6HL2G3sBb9O4UjIRYs0g5GLYA1Enpk/s480/pic-agenda-483-8010600.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="480" data-original-width="480" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZjPuC1eZ0ZIBrQTDWpJWshOzaODvTnt3nyahcBSnUCypAXTCb1xj9bT26IJpXvUZccXjC4o-x9F6qTV4Z1K4-NK9zBEljDBaTME3BNOHIUUdvgEI1whoAi6CqZBlF-SwK5qFyrhujoRbE2zz7Fl3FJ-GRHZ6HL2G3sBb9O4UjIRYs0g5GLYA1Enpk/s320/pic-agenda-483-8010600.jpg" width="320" /></a></div></div><div><span style="font-family: courier;">The box contains a built-in voltage stabilizer, which reduces the input supply voltage to 6V =, which allows the box "A" to directly supply the RF-10 radio without a battery. The 6V output used to power the radio station is marked - + and a "square with antenna" (it is the 6th and 7th screw terminals counted from the left, looking at the back of the cabinet). A plug-in connector is connected to these terminals, which connects the power supply from box "A" to the back of the radio station instead of the battery pack. BEWARE OF POLARITY, AVOID SHORT CIRCUIT !! </span></div><div><span style="font-family: courier;"><br /></span></div><div><span style="font-family: courier;">Box "A" also contains a current source 0.3 ... 0.45A which can be used as a hand-held charger for charging one battery block of the RF-10 station. It is possible to charge the battery box both during operation of the radio station (if it is powered from the box "A"), or completely without it, only using the bare box "A" without other accessories. A plug-in bracket (accessory part) is used to connect the battery pack, on which the battery pack is hung in the same system as on the radio, or in an emergency only a plastic plug-in connector is used and the wires from it are connected to box "A" on screw terminals + - marked with battery (it's the 9th and 10th screw terminals counted from the left, looking at the back of the box). Charging is switched on with the toggle switch to position "I" (toggle switch first from the left when looking at the front panel of the cabinet) and charging is signaled by a lit green light above the switch marked with the battery symbol (first from left when looking at the front panel). The battery charging time corresponds to the parameters specified in the battery maintenance and recharging manual. </span></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQOgD3Gti004u1vqvYFWMUoF7LHWh5fcVUsfue6u7OMlOAOV9qu3P4QoimLAgKmYteKjKD5BRF870DKeOl8D9DlKCW1zX2jn8g9GfbsP5B3cgeLTtsQCBQtZQbApCmsQyvww1z94H9Mw2mkgvx7aicxVRknUq9LiPZ6GvtTQ_75GVXlu-dOkNliucD/s480/pic-8010600-2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="480" data-original-width="480" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQOgD3Gti004u1vqvYFWMUoF7LHWh5fcVUsfue6u7OMlOAOV9qu3P4QoimLAgKmYteKjKD5BRF870DKeOl8D9DlKCW1zX2jn8g9GfbsP5B3cgeLTtsQCBQtZQbApCmsQyvww1z94H9Mw2mkgvx7aicxVRknUq9LiPZ6GvtTQ_75GVXlu-dOkNliucD/s320/pic-8010600-2.jpg" width="320" /></a></div><div><span style="font-family: courier;">Box "A" contains low-frequency power amplifier and an intercom amplifier. The volume of the amplifier is controlled by rotary switches with earphone and speaker symbols. To use these circuits, you need to unscrew the handset cable from the radio and screw it into the connector on the back of the cabinet "A", which is marked with the handset symbol (it is the connector on the far right, looking at the back of the cabinet). Instead of the handset, a connector of a special connecting cable (part of the accessories for box "A") comes to the connector of the RF-10 radio station and the other end of this multi-core cable into the connector on box "A" marked with a "square with antenna" (it is the 1st connector - counted from the left, looking at the back of the cabinet). Next, a speaker with an impedance of 8 ohms is connected to the box "A" (it is the 3rd and 4th screw terminals counted from the left, looking at the back of the box). With this connection, it is possible to listen loudly to the received session from the radio station to the loudspeaker (rotary function switch switched to position "A" with a vertical double arrow). </span></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjqdGNR8CtMIxlS1CIaNN7INWmVCzJLs7WrgGUIM00XG4icYkmednK2LHrItneoYqlg2zb-PQhXr7gBiLL70cF0Yenn-1XsLq1vqccV5HEQsB1VBTFBlhjhVmGSOdXAHuHKAzbyF5alHGeGYJbfIIIjHGoyyiBWaggc12nGaH0hvaii5vTj92yfA6Cv/s480/pic-8010600-3.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="480" data-original-width="480" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjqdGNR8CtMIxlS1CIaNN7INWmVCzJLs7WrgGUIM00XG4icYkmednK2LHrItneoYqlg2zb-PQhXr7gBiLL70cF0Yenn-1XsLq1vqccV5HEQsB1VBTFBlhjhVmGSOdXAHuHKAzbyF5alHGeGYJbfIIIjHGoyyiBWaggc12nGaH0hvaii5vTj92yfA6Cv/s320/pic-8010600-3.jpg" width="320" /></a></div></div><div><span style="font-family: courier;">If there is another accessory box marked "B" to which a second loudspeaker and a second handset can be connected, the device can also be used as an intercom inside the vehicle (rotary function switch switched to position "AB").

Hi all,<br />
<br />
as I promised some time ago there is the first part of big review video of the RF-10 (TAKT 1) manpack radio posted on my YouTube channel:<br />
<br />
<a href="https://youtu.be/bO6BWXuJNTE">https://youtu.be/bO6BWXuJNTE</a><br />
<br />
The radioset RF-10 was developed in between 60's-70's of last century. This set with coded name "TAKT 1" was dedicated for tactical operation in squadrons and troops patrols or headquarters company. It was taken into service in 70's and used till the end of 80's. More than 30.000 pcs was manufactured. In the beggining of 90's this radio set was replaced by RF-13 (coded name Radmila) mainly because of digital and encrypted communication needs.<br />
<br />
The technology employed significantly outdistanced other competitors. For example USA in the 70's used PRC-77 which the RF-10 greatly surpassed in smaller size, usefulness, lower weight, etc. In those days Czech army used RF-10 mainly for communication on company level, but the utility did not end there, thanks to its adaptability they were mounted in the vehicles, served as telephone relays, also they found use in fire fighting, civil defense, flooding areas rescuing etc.<br />

Hi all,<br />
<br />
are you interested in the CSLA bayonet which was used as the part of SA-58 rifles?<br />
<br />
Here I am posting my short video about this well known and popular bayonet weapon which is still requested by many collectors around the world.<br />
<br />
<a href="https://youtu.be/bxFBNVHUmw0">https://youtu.be/bxFBNVHUmw0</a><br />
<br />
There is several videos and dozen of comments about the legendary CSLA bayonet vz.58 as the accessory of the Czechoslovak assault riffle SA58 on Youtube... There is lot of complains and rumor about this weapon but what is truth and was is not? Is the bayonet vz.58 full tang or not, is it good for the battle or not? Lets see the video with little explanation of few things.<br />
<br />
Do not hesitate to ask for any question regarding this bayonet weapon as I did not covered all tasks for sure and I will be happy for any kind of comments (even negative one :) <br />

<span style="font-family: "Courier New", Courier, monospace;">Radiostanice typu super-regenerative se řadí do společné série radiostanic PbC(RBS), PPC(RRS) a PPY(RRU).<br /><br />RRS(PPC) byla vyráběna v Rusku v letech 1940 a dále, byla osazena elektronkami typu 2x UB-240 společnými pro vysílač i přijímač. V přepravní i pracovní poloze byl komplet umístěn na přesce v pouzdru(tašce) nošené přes rameno. Napájen byl ze suchých článků na spodu pouzdra.<br /><br />Pracovní rozsah radiostanice byl 32,4 - 36,8 MHz v jednom rozsahu. Ladení mělo značky (kanály) 66-98 t.j. celkem 33 pracovních kanálů. Anténu tohoto kompletu tvořil prut o délce 1,6m, vybavený vrchním kapacitním štětinovým kloboukem, standardním pro tyto stanice. Tento typ antén byl velmi častý a lze se s ním setkat i u dalších radiostanic vyšších výkonů typu man-pack. Dosah kompletu RRS(PPC) byl přibližně 500m, což při váze 3,5kg a rozměrům 170x250x60mm a nakonec i použitému pásmu bylo vcelku odpovídající. <br /><br />Paramtery:<br /><br />Rozsah: 32,4 - 36,8 MHz<br />Napájení: suché články<br />Elektronky: 2x UB-240<br />Anténa: prut 1,6m s kapacitním kloboukem<br />Váha: 3,5kg<br />Rozměry: 170x250x60mm<br /><br />V této době bylo k dispozici samozřejmě mnoho dalších radiostanic podobných parametrů. Britské radiosety typu No.13, No.27 a SCR 195. Tyto stanice byly postupně vyřazovány jako nevyhovující a následně byly nahrazovány např. US modelem SCR-300 a posléze byl tento model prevzat v Británii jako WS No.31. Nakonec i britský Set No.38 přestože byl velmi jednoduchý, k nošení nepraktický, nebyl o nic horší ve svých radiových parametrech při srovnání s výše uvedenými souputníky ostatních armád.<br /><br /><br />73 - Petr, OK1RP</span><br /><span style="font-family: "Courier New", Courier, monospace;">Zdroj:<br />- vlastní poznámky a dokumentace<br />- Foreign Military Weapons and Equipment, Vol VI Signal Equipment, Dept. of the Army, Pamphlet Nr. 30-11-1</span> Petr, OK1RPhttp://www.blogger.com/profile/11092364724802787693noreply@blogger.com0tag:blogger.com,1999:blog-2443470820699486974.post-56438661213931942142015-10-09T14:22:00.000-07:002015-10-09T14:22:55.029-07:00PbC/4-P (RBS/4-R)<span style="font-family: "Courier New", Courier, monospace;">PbC(RBS) je identicka radiostanice s 4-P(4-R).

Nejedna se jen o podobu, protoze prislusenstvi PRC-25/PRC-77 jako jsou handsety, headsety, anteny, bateriove boxy a dalsi prislusenstvi je shodne a pouzitelne take pro obe verze PRC-1099/A, protoze jsou v souladu s US standardem pro zapojeni systemovych konektoru.<br /><br />Prestoze radiostanice se u armady i v civilnim sektoru "proslavila" spise spatnymi vlastnosti (v armadnim sektoru i svou cenou presahujici $6000 pro zakladni verzi), radiostanice mela i sve kladne stranky. Modernizovana verze mela 100 programovatelnych pameti, v automobilove zastavbe umoznovala az 1kW vykonu s prislusnym zesilovacem, transceiver ma slusne fungujici vestaveny automaticky tuner, umoznuje provoz ALE dle standardu FED-STD-1045 ALE apod.</span><br />

<span style="font-family: "Courier New", Courier, monospace;">Verze PRC-1099A je diky zmenene topologii obvodoveho reseni v mnohych parametrech lepsi. <br /><br />Byly odstraneny potize s kvalitou audio signalu, standardizace zapojeni s US vojenskymi konektory (zapojeni pinu a typu), vyrazne zlepseni intermodulacni odolnosti, odstraneni potizi s prepinanim TX/RX. Oproti puvodni verzi ma 1099A i kvalitnejsi tesneni skrine. <br /><br />Datron je udajne tuto verzi stale schopen servisovat. Stale se vsak cena techto stanic na trhu pohybuje kolem $2k za pouzity kus a nahradni dily/moduly je velmi obtizne sehnat.<br /><br />Stale u nekterych kusu 1099A pretrvavaji potize s nabijenim a u nekterych kusu se projevovaly potize s pristupem k nekterym pametovym mistum v bankach.</span><br />
