Fortunately, the ARRL Antenna Handbook companion CD (you know!, the one in the back of the book!) contains a software package called HFTA or HF Terrain Analysis developed by Dean Straw, N6BV when he was the handbook Editor at ARRL. HFTA models horizontal antennas (dipoles, simple yagis, stacked yagis) at specified heights over terrain and plots the modeled antenna gain at different elevation. Radio propagation Radio propagation is the study of how radio waves travel from a transmitter site to a receiver site through the atmosphere. Radio signals are affected by terrain elevation between the sites, and obstructions, including trees, buildings, etc. that may be in between the two sites.

The complex computations of convolution or Fourier transformation are replaced. The proposed model is easy to be implemented in real-time simulators and can vary the channel parameters online. Simulation results show the validity of the proposed model. More analytical studies are needed to verify the proposed.
5. The tools provided by this web application enable users to predict available frequencies, signal levels and corresponding reliabilities for High Frequency (HF) circuits. All predictions are performed using the ITU's ITURHFPROP application; a software method for the prediction of the performance of HF circuits in accordance with Recommendation ITU-R P.533-13
6. The lower the readings, the better HF / shortwave propagation conditions are. Ranges are A1-A9,B1-B9,C1-C9,M1-M9,X1 and up. Low readings, especially in the A range, generally indicate good conditions. Higher readings can indicate poor conditions. Solar flares can cause readings to jump into the M and X range, which can cause radio blackouts for paths in the sunlit area

• object lesson in HF propagation. The contest covers the 80, 40, 20, 15 and 10m bands and runs for 24 hours, one diurnal cycle. This year the solar flux was just above 140 with an A index of four; in other words reasonably settled band conditions with expectations of a maximum usable frequency (MUF) high enough to support 10m propagation Tim Kirby, in his VHF column, reports that some trans.

As we head down into the sunspot number trench that looks to be as deep as 2009, we can correlate QSO data from a state QSO Party to understand the effects on propagation.

• Overview of HF Propagation • Characteristics of HF radio propagation - Propagation is possible over thousands of miles. - It is highly variable. It has daily and seasonal variation, as well as a much longer 11 year cycle. • HF radio waves may travel by any of the following modes: - Ground Wave - Direct Wave (line-of-sight) - Sky Wave. Ground Waves • In the HF region, the ground.

On HF this is commonly caused by refraction (bending) of the signal at the upper layers of the atmosphere known as the ionosphere. On frequencies higher than this, while solar activity plays a role, Earth based weather events are the most common cause of propagation. These links explore several sites, and software, that can be used to help predict how a HF signal will propagate. For. A central topic of this presentation is why much of the rebirth of HF is due to advancements in a wide range of fields, such as antenna design and digital modulation schemes, as well as improvements in our understanding of propagation and how we can adapt to the challenges of propagation at HF.
