2-5-2011 - R. Verdad (tent)
2-5-2011, GUATEMALA, R. Verdad (tent), 4052.5 AM, very weak SS,
apparent conversation, SINPO 15231. Not sure what they are using for a TX now, but fair signal. Bruce Jensen, CA, USA R75 & 60 foot random wire |

Bruce Jensen, CA, USA R75& 60 foot random wire Bruce, could you check 1480 Khz AM? I think it's from Texas. Spanish speaking. I got it some months ago, but not much luck lately. mike |

Bruce Jensen, CA, USA R75& 60 foot random wire 60 feet is too short. Even if you have radical bends a longer wire will work better. You could always try the loop. http://hb9tmw.free.fr/EuroNet/HTML/fullloopant.html |

You could always try the loop. http://hb9tmw.free.fr/EuroNet/HTML/fullloopant.html Well - yes, it's too short - and yet it still overloads all of my radii with signals from 50 kW 1100 AM about 2 miles away...and that's just the beginning. RF Hell is right here. I do have a QSL from them though, and for a signal that was considerably weaker than this one :-) |

It's the new one. Well, yes, that's right, an inverted L. The vertical is about 30 feet, the horizontal about 60. Oriented nearly north-south (not checked with a compass), far end is south. Guatemala is off the forward left side if you looking the direction the antenna is aimed. How much does the 30 vertical do for you, other than collect vertically polarized QRM? The only reason, really, I built it this way was to allow the 9:1 antenna unun to be mounted near ground (the ground is not in place yet, but will be soon). Otherwise, I would have put the whole thing up high, or possibly sloped with the unun end down. Once you get your ground in place, experiment with variations of the installation. You do have a quite a bit of antenna, there. Verify that you've not got too much. Look for images, indicating overload. A pad may be required. This morning (1800z onward), the VOA relays from MDG and BOT (Africa) on 16 and 19 meters were coming in almost like locals. Bruce |

Verify that you've not got too much. Look for images, indicating overload. A pad may be required.. Bruce Oh, I have overload for sure - I need that attenuator certain times of day. Not sure what I can do for variations? After I get the ground in, the only thing left to add is the Isolator and that's it. Gotta be honest - any less length/height and I won't hear a damn thing below 5 MHz, and those are my favorite bands by far. The weakness of those bands compared to anywhere else I've lived is ridiculous. A large full-wave loop for 90m would be great. Almost impossible to fit, but great. If this does not work, I am just going to buy myself 1,000 feet or wire and head for the most remote beach I can drive to. Ron Howard has great results over at Asilomar near Carmel. |

You said. The solar flux is still just barely above 80. |
