?? Upcoming Changes to DTT in Spain Digital Terrestrial Television (DTT) in Spain is transitioning from DVB-T to DVB-T2, the second-generation DTT standard. ?? Key Points: - Three new UHD channels on the DVB-T2 system are coming soon. - Transmission efficiency will improve by approximately 50%. - Measurement equipment must support DVB-T2 modulation and distinguish between HD and UHD-4K. ?? PROMAX field meters, starting from the RANGER series, are ready for second-generation DTT. Learn more in the news article: https://lnkd.in/dmup8eu5 #DBT #DVBT2 #DTT

?? Curious About the Differences Between MF and HF Radio? ?? ?? Medium Frequency (MF) radio operates between 300 kHz and 3 MHz, while High Frequency (HF) radio covers 3 MHz to 30 MHz. ?? ?? MF radio is commonly used for AM broadcasting and maritime communication. ?? ??? HF radio is ideal for long-distance communication, often used by amateur radio operators and in aviation. ?? ?? MF signals are less affected by atmospheric noise, but HF signals can travel further due to ionospheric reflection. ?? ??? Choose MF for regional coverage and HF for global reach! ?? https://lnkd.in/eZw8HMjA #RadioCommunication #MFvsHF #Ruixue #RadioTechnology #AmateurRadio #Broadcasting

The #broadcasting sector had earlier opposed moves by the government to take away #spectrum in the mid-band for 5G #services, saying it would impact their operations. The #DoT, however, believes that mid-band is the most suited spectrum for #5G, and additional #airwaves should be made available to telcos through #auction.

In 1949, officers of the??Office of Policy Coordination /OPC) began discussing the use of Radio Nacional de Espana (RNE) as a tool in the psychological warfare campaign against the USSR. An “official dispatch” OPC message dated May 30, 1949, on the subject Radio Nacional Propaganda Broadcasts contained the outline of how to use RNE: Information here indicates that Madrid is heard reasonably well in satellite areas. If the Spanish Government, through proper covert arrangements, is will to place the facilities and broadcast time of the station as the disposal of (redacted), this would clearly open up the possibility of using Madrid as an operational outlet for broadcasts, whether sponsored by or accordingly produced by the U.S. Government. Assuming the broadcasts can be heard satisfactorily in the target areas and time and facilities could be made available to (redacted), it would seem there are four problems to be met: a.?????Cover for the operation.?? b.?????Policy control.?? c.?????Type of broadcasts in relation to audience reaction.?? d.?????A competent production organization.
