Construction of a new transmitter began in 1950 and was completed in December 1951. Tests lasted until February 1952. Its power output was 400&#160;kW (2x 200&#160;kW). In its first broadcasts it was transmitting the radio programme "Československo 1", later "Hvězda". </p><p>From 1957–1958 Topolná was also used to transmit a Hungarian radio programme on 49 meter wavelength. From 1953–1960 and again from 1969–1973 one of its masts was used for transmission on frequency 173&#160;kHz. Between 1975 and 1978 the transmitter was reconstructed and from November 1978 its transmission power increased to 1500&#160;kW. </p><p>On 1 October 1989 the frequency was changed to 270&#160;kHz. After the <a href="/wiki/Velvet_Revolution" title="Velvet Revolution">Velvet Revolution</a> in 1989 the broadcast programme was renamed from "Hvězda" to "Radiožurnál". In January 1994 one of the masts was switched off to cut costs, reducing the output power to 750&#160;kW. Further reduction of output power followed in January 2002, to 650&#160;kW. As there were very few other transmitters working on the frequency 270&#160;kHz its programme ("ČRo 1 – Radiožurnál") was clearly received across the whole of Europe, especially during the night.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> </p><p>Since the mid-2000s <a href="/wiki/Czech_Radio" title="Czech Radio">Czech Radio</a> has announced its intention to close down the transmitter several times.

This radiation pattern ensured that the Topolná transmitter can be received clearly in all parts of the Czech Republic and <a href="/wiki/Slovakia" title="Slovakia">Slovakia</a>. </p><p>To create this directional antenna pattern two 257 metres (843&#160;ft) tall guyed lattice steel masts were used. Until the mid-1970s these masts were used as ground-fed mast radiators and are therefore insulated against the ground. In the mid-1970s the transmission power was increased to 1500&#160;kW, making the Topolná transmitter one of the most powerful transmitters in Europe. By this measure, both masts were equipped with cage wire antennas, which made their electrical insulation against the ground obsolete. After the installation of these cage antennas the basement insulators were bridged, but remained in place. </p><p>As in other high power transmission facilities in Central and Eastern Europe, the Topolná transmitter used special overhead lines to transmit the RF-power from the transmitter building to the masts. </p> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Topoln%C3%A1_transmitter&amp;action=edit&amp;section=3" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text"><style data-mw-deduplicate="TemplateStyles:r1238218222">.mw-parser-output cite.citation{font-style:inherit;word-wrap:break-word}.mw-parser-output .citation q{quotes:"\"""\"""'""'"}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}.mw-parser-output .id-lock-free.id-lock-free a{background:url("//upload.wikimedia.org/wikipedia/commons/6/65/Lock-green.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-limited.id-lock-limited a,.mw-parser-output .id-lock-registration.id-lock-registration a{background:url("//upload.wikimedia.org/wikipedia/commons/d/d6/Lock-gray-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-subscription.id-lock-subscription a{background:url("//upload.wikimedia.org/wikipedia/commons/a/aa/Lock-red-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .cs1-ws-icon a{background:url("//upload.wikimedia.org/wikipedia/commons/4/4c/Wikisource-logo.svg")right 0.1em center/12px no-repeat}body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-free a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-limited a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-registration a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-subscription a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .cs1-ws-icon a{background-size:contain;padding:0 1em 0 0}.mw-parser-output .cs1-code{color:inherit;background:inherit;border:none;padding:inherit}.mw-parser-output .cs1-hidden-error{display:none;color:var(--color-error,#d33)}.mw-parser-output .cs1-visible-error{color:var(--color-error,#d33)}.mw-parser-output .cs1-maint{display:none;color:#085;margin-left:0.3em}.mw-parser-output .cs1-kern-left{padding-left:0.2em}.mw-parser-output .cs1-kern-right{padding-right:0.2em}.mw-parser-output .citation .mw-selflink{font-weight:inherit}@media screen{.mw-parser-output .cs1-format{font-size:95%}html.skin-theme-clientpref-night .mw-parser-output .cs1-maint{color:#18911f}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .cs1-maint{color:#18911f}}</style><cite class="citation web cs1"><a rel="nofollow" class="external text" href="http://www.radioheritage.net/europe/frequencies-1948-copenhagen.htm">"European Radio History - 1948 Copenhagen frequency plan"</a>. <i>Radioheritage.net</i><span class="reference-accessdate">.
