Very short duration skip
Hello All:
Anybody getting DX skip stations that come in and go in a matter of only a few seconds. I have a 2 and a 4 element quad beam antenna up and testing. I have this fast in and out skip stations on all of my antennas. Jay in the Mojave |

Jay in the Mojave Hello Jay I had a bit of that over the weekend but the band has been fairly quiet over here for the past week or so otherwise. The ground-wave has still been in there fairly consistent. |

Hearing stations 100 miles away, no problem, and back east. Should be gettin skip condations this weekend I hope. Jay in the Mojave |

Jay in the Mojave It may be that you are getting short propagation events from the ionized tails of meteors reflecting distant signals . There have been long-haul comm systems built to utilize this effect, they sound for a path and send a data burst when there is an open path. phil |

Then again if the atmosphere is quiet enough it could be possible. I know that one can get sporadic E for periods between 10 seconds to on hour range. james |

Jay in the Mojave Hi Jay That 100 mile mark makes it fun, I like it more than DX mostly because you can usually carry on a qso with the guy much longer than a skip contact. It's a better test of your gear too, imo. |

This happens a few times an hour, then the skip stations come in solid for say 20 mins or so. I believe I was using some sort of meteor a few years back, as I was talking to guy about 150 miles away, the signal level came up then quickly died, but we where able to exchange locations and call signs on 11 meters.
