Weather Looks Good!
The weather looks great for the weekend....I hope!
Alien will be visiting Norwalk and I'll be hailing Binary Jane on Channel 9 from 11:00 am to 2:00 pm or so. RB |

Say hello to any Norwalk Islands Sharpies you see for me. Don't
sink any old Laser dinghy you might come across, either (sail No 1 used to live there) Okay! We loaded up the boat's freezer with steak and fish last night, so we're all set. I hope someone reminds me to bring fresh batteries for the GPS... RB |

Why not leave the old ones out in the sun for a while to

Alien will be visiting Norwalk and I'll be hailing Binary Jane on Channel 9
from 11:00 am to 2:00 pm or so. I don't think your radio will be able to reach me 50 miles up the coast. We may sail further up and my radio really has amazing range. From Execution Rocks I was able to speak to someone at Morris Cove without too much trouble. RB |

I was able to reach a fellow on a Columbia 36 who had initially alerted me that there was a guest mooring open. We spoke on channel 9, tried to switch to 68, but there was too much chatter there. If your rig can't make 30 miles or more, something's wrong. RB |

It's not the rig that determines range, it's the radio horizon doofus.
Does your handheld make 30 miles? If not what's wrong with it? "Bobsprit" wrote in message ... We may sail further up and my radio really has amazing range.

Then how is it that my handheld will reach Oyster Bay set to 5 watts, but not on 1 watt? Hmmmmm!??? RB |

How is it that you can have a conversation from Execution Rocks to Morris Cove using your rig with "amazing range", when the other radio is, presumably, a standard output? Does your radio really have "amazing range", or was your example irrelevant? For the benefit of those of us who are unfamiliar with the area, what is the distance between Execution Rocks and Morris Cove? -- Wally www.makearatherlonglinkthattakesyounowhere.com Things are always clearer in the cold, post-upload light. |

Cove using your rig with "amazing range", when the other radio is, presumably, a standard output? The fellow at Morris cove had a hell of a radio...a very expensive Icom with a whip at the his masthead. I heard him with some static. somewhat faint. He apparently heard me better, loud, but said my signal got chopped a few times. Making a 40-50 mile shout on a VHF is possible. I reach beyond Huntington with ease where a friend keeps his Cape Dory. His cheap Uniden barely reaches me however. RB |

Please explain to us how to determine the "radio horizon doofus." How is this different
from the "visual horizon doofus"? Flounder wrote: It's not the rig that determines range, it's the radio horizon doofus. Does your handheld make 30 miles? If not what's wrong with it?

What is the height of the antenna mounting? What length is the whip? Don't know the height of the Columbia 36 masthead...I'll guess at 45 feet. RB |

45 or so. Whip is under two feet, I believe. RB |

I assume you're aware that VHF signals, while mainly line of sight, are capable of greater range on occasion. RB |

To be honest, I was quite shocked to make the shout over 40 miles so clearly. It's the best I've managed. RB |

It does seem quite a long way - perhaps the conditions were particularly
favourable. What sort of range does your radio normally manage? I can generally make the Oyster Bay area...around 12-15 miles, with ease. I had steady contact with a friend beyond Huntington for a while, so I'd put average range at 20-30 miles. Anything above that is a gift in this area. RB |

Just about any text I can find lists typical ranges as 5-25 miles, The range over the horizon is highly dependent on the heights of the antennae. A couple of twigs at 50 feet have a l-o-s range of a little over 16nm. I'm doubtful that said twigs could 'typically' reach 25nm. However, if said twigs were each about 100-120 above the water, on ships, say, then 25 miles might be typical. You, however, claim an *average* of 20-30 miles. The fact that some situations can produce a typical range of 25 miles in no way substantiates your claim. -- Wally www.makearatherlonglinkthattakesyounowhere.com Things are always clearer in the cold, post-upload light. |

Up to 800 miles. However, this is very extreme. The phenomena used is atmospheric
ducting, which is common when hot air overrides colder air - very common on the ocean in the summer. Also, "line of sight" is a bit misleading, since radio waves (and radar) refract a bit in the atmosphere, to the horizon is a bit further. The distance calculation is often given as "1.22 times the sum of the square roots of the antenna heights." Assuming masts of 49 feet, this lead to a distance of 17 miles. However, in open water its very common to hear chatter from 25 miles or further. Last Friday while I was still south of Plymouth, I heard chatter from Salem Bay - maybe 50 miles away. BTW, there is a theory that very long distance VHF propagation is correlated with earthquake activity, so if you hear a pickup request from 500 miles away, prepare for a tsunami! -jeff Wally wrote: Bobsprit wrote: What is the line of sight distance between the two antennae?

You can easily reach the space shuttle with that power and frequency. In fact, you should be able to trip geosynchronous satellites too. Buffoon you are! "Bobsprit" wrote in message ...

Because your fat head absorbs the signal. It really does.

Wally appears to be caught in the Mooron syndrome.
VHF will cover commonly up to about 80miles, that's why you use Lo Po if comms are possible at shorter range on Lo Po. Well, I've never gotten a signal 80 miles. Too much chatter here to even have a chance at that. But the 40-50 mile shout has happened. I see wally is very quiet. I guess he's not the sort of man who steps up the plate and says he was mistaken. Oh well. RB |

It looks like you're using a height of 46 feet and a coefficient of 1.22. This is the
correct answer to the problem, not that its particularly relevent to how for Boobie could transmit. However, its the Radio line of sight, not the Visual. Distance to the visual horizon uses a coeficient of 1.17.
