1. Exercises in HF sounds
2. As for his Holiness himself, he was treated to a ride from Gatwick to Victoria behind the Royal loco No 73142 Broadlands bearing the special Southern headcode "HF" (Holy Father).
3. The CAA is investigating the application and benefits of satcoms to meet anticipated growth in air traffic on North Atlantic routes, where position reporting is currently dependent on HF voice communications.
4. As a non-physicist I have often wondered if the difference in photon energy ( E' - E = hf' - hf ) of the shifted and unshifted light could be wholly accounted for by the effect of the surface velocity ( v ) acting together with the particle equivalent mass of the photon.
5. This radiation may increase the depth of the "D" layer due to ionisation and produce the all too well known Dellinger face out when long-distance HF communication ceases abruptly.
6. HF Luton
7. Measuring the direction of the Earth's magnetic field provides the basis of an electronic compass while the strength of the field says much about solar activity, a factor important to HF radio propagation.

10. Compare sentences to which one more HF sound is added:
11. They are told enough to identify each substance as its molecular model is made ( eg H 2 toy balloons; HF, etching glass; CH 4 explosions in mines) and are soon writing molecular formulae.
12. Measuring the directions of the Earth's magnetic field provides the basis of an electronic compass while the strength of the field says much about solar activity - a factor important to HF radio propagation.
