Propagation at the moment
Looks like things are going down hill for a Sunday evening. Earlier New
Zealand and Australia faded out and Radio Netherlands out of Antilles is sounding weak and noisy. Currently G1 level geomagnetic and S2 Solar radiation storms in progress. -- Telamon Ventura, California |

Telamon, Things are starting to slide here in the Midwest USA as well. Right
now the 31 meter band seems like the best bet in this neck of the woods. I am presently tuned to The Voice of Greece, at 0709utc on 9420khz. I've got a solid 5dB/S-9, on the JRC NRD-535D, hooked up to the Par Electronics EF-SWL. If this upcoming storm lives up to it's prediction, I may be forced to actually do some dusting and vacuuming around the shack for the next couple of days. Good DXing to you, Gary, Illinois, USA |

For One and All,

Radio Propagation http://www.smeter.net/propagation/propagation.php .. * View the exact current gray-line position on Earth. Current Gray-Line on Earth Current Gray-Line on a World Topographical Map Special ionospheric propagation conditions often exist between two or more stations simultaneously . . . .. * Current Sun View of Earth Current Solar High-Noon & Gray-Line The current position of the Sun over the Earth is a primary factor determining current radio propagation conditions . . . .. * Current Moon View of Earth Current View of Earth from the Moon The current position of the Moon over the Earth is important to Earth-Moon-Earth (EME) moon-bounce communications, because . . . .. * Northern Hemisphere Aurora Northern Hemisphere Auroral Activity Displays a statistical plot that provides an estimate of the location, intensity and extent of current northern hemisphere aurora . . . .. * Southern Hemisphere Aurora Southern Hemisphere Auroral Activity Displays a statistical plot that provides an estimate of the location, intensity and extent of current southern hemisphere aurora . . . .. FREE "DOWNLOADS" - Radio Propagation Analysis Programs .. * Run these free radio propagation programs from the web or download and run them from your hard drive. .. * Diffraction 1 Radio Propagation by Diffraction Over an Obstruction When there are two radio antennas located on or near the Earth's surface propagation can ordinarily occur between them by groundwave. If an obstruction, a hill, a mountain, a building intervenes, propagation can still occur via slant paths over the top edge of the obstruction. This depends on diffraction over the edge. So, in addition to the basic or spreading loss along the sum of the slant paths, D1+D2, there is an additional loss due to diffraction . . . .. * Diffraction 2 Radio Propagation by Diffraction Over Two Successive Obstructions This program calculates the overall transmitter-to-receiver loss when the radio path includes diffraction over two successive obstructions. Results include field strength at the receiving site. Antenna efficiency can be allowed for . . . .. * Groundwave Groundwave Propagation vs. Path-length & Frequency for Various Terrains Both transmitting and receiving antennas are verticals, height = 1/4-wavelength or less, above a system of buried radial wires. A 1/2-wave vertical has 1 dB more gain than a short vertical. A 5/8-wave vertical has 1.6 dB more gain . . . .. Line-of-Sight Propagation Over Line-of-Sight Radio Paths This program covers just the essentials. Refraction in the Earth's atmosphere, ground reflections and antenna radiating efficiency are not taken into account . . . .. * Two-Hops Sky-Wave Trigonometry For given one-hop ground path distance and height of reflecting layer this program calculates radio path distances and the radio-path elevation angle . . . .. .. .. iane ~ RHF ..

Currently Solar radiation storms in progress so if the whole path from a station to you is in the dark reception might be OK. Very good this evening. Radio Australia and New Zealand from the sunny side of the earth with big signals on the 19 meter band. -- Telamon Ventura, California |

UTC 1/23/05 Sun 17:20 Very good this morning. Signals on 31 and 16 meter bands are much stronger than usual. Asia region with North Korea, India, Japan, China and also more southernly Australia very strong this morning. -- Telamon Ventura, California |

Oh well time to look at the lower bands. Another thread indicates things may be better there. -- Telamon Ventura, California |
