According to Digital Rozhlas, it is now longer available on the DVB-T regional network and DVB-T multiplexes 12, 22 and 23.
It adds that its findings indicate this could be due to broadcasting debts the channel has incurred.
At the same time, the sister channel Slagr TV remains on the terrestrial platform.
Slagr 2 can now only be seen by cable and IPTV subscribers, as well as those of Skylink, via Astra 3B at 23.5 degrees East.
The channel was launched in late 2017 and covered almost the entire population.
