The main innovations relate to the use of active antennae, miniaturization of radioelectric functions and the introduction of new frequency bands

Spectrum display and demodulator of IQ radio data

Various studies are being carried out to examine the technical constraints associated with radio frequency allocations and related provisions for space radiocommunications below 3 GHz with a view to facilitating the use of those frequency bands.

The observational data have been used in supporting frequency prediction for HF radio communication.

Your radio transmitter's on the wrong frequency.

The communications package includes an S band downlink and amateur radio store and forward communications with an audio repeater to stimulate radio interest among schoolchildren.

Payne, your radio'll be on Company frequency. Coleman, you're on Battalion.

This is a radio frequency ID system.

The results of soundings were used to develop frequency prediction for HF radio communication in Indonesia.

That's why the rental job with a police callband.

That spectral region was one of particular importance to radio astronomy since there were many interstellar line emissions.

Antenna VHF mobile

In view of the rapid increase in the use of frequency bands for various services, efforts are being made to update the international radio regulatory process and to prepare for future requirements.

External postal and telecommunications services, with the exception of government communications and the regulation of radio frequencies

UHF base station antennas

Watson was in fact listening to very low frequency radio emissions caused by nature.

They will also discuss the content and frequency of television and radio programmes for older persons.

Nonlinear video editor for KDE

The Working Group was informed that the fifth preambular paragraph recalled the fact that the a priori allocation plans adopted by the ITU administrative radio conferences guaranteed equitable access to the geostationary satellite orbit and the radio frequencies for direct broadcasting satellite and fixed satellite services.

The Group did not consider the installation of radio frequency grounds passes to be a priority at the moment.

It consisted of a two way audio channel and one way black and white video link.

HF broad band antenna folded dipole

Coordination must be completed before the frequency assignments in question were brought into use or notified to the Radiocommunication Bureau.

For example, in addition to the visible channel and the infrared channel, a water vapour channel has been newly introduced.

This invention makes possible the location of several thousand mobiles on a single radio channel.

VHF fibreglass antenna (144 162 MHz)

2. In using frequency bands for radio services, Members shall bear in mind that radio frequencies and the Geostationary Satellite Orbit are limited natural resources and that they must be used rationally, efficiently and economically, in conformity with the provisions of the Radio Regulations, so that countries or groups of countries may have equitable access to both, taking into account the special needs of the developing countries and the geographical situation of particular countries.

Traditional means of communication radio, television and publications

Radio was the most ubiquitous communication device in the world.

One on the auroral probe POLRAD the radio spectro polarimeter to measure electromagnetic auroral kilometric radiation.

After we have recovered the container and verified its contents you will be notified on radio frequency 1 6.23 megacycIes where the atomic bombs may be recovered.

On 20 May 2003, the station had used four new frequencies that had caused interference on Cuban radio transmissions and had availed itself of a United States Air Force plane to transmit the television signal at peak viewing time, using channels reserved by law for Cuban stations.

called front task force through the video.

That was our HF radio antenna.

lots of different recommendations systems and who knows what will work best we have a chance to try it all and see what falls out

This is a video prototype.
