Presumed LRA36, Antarctica on 15476 at 1900 with programming in Spanish. Seems
to be USB only with a slight carrier. dxAce Michigan USA |

Steve - Can you give some idea of the signal strength on this puppy? Not much! barely moved the meter. I lost them at 1938 today. Didn't hear them until almost 2000 yesterday and had them up until about the time they went off at 2100. I've not heard a definitive ID on this one yet, but everything seems to fit. Maybe tomorrow I'll actually put the cans on and give a good listen. O, I just turned up the volume, and they are back! Had it down as I was on 2 meters yakking. dxAce Michigan USA |

Prior to 1900 though they are pretty well blocked, at least here, by Africa No. 1 on 15475. dxAce Michigan USA |

Thanks, though - one day it will change. Bruce Jensen |

Thanks, though - one day it will change. Bruce Jensen I'm in the same boat. I live in a location that's far from ideal when it comes to DX. However, I find it hard to get a fix on just how bad it is. The amount of ambient noise I measure with an s-meter varies dramatically with the band, time of day...even the antenna I'm using. It's hard to get a fix on how it all averages out...though I'm sure it ain't great. At the same time, it's interesting to check out the Salt Lake City receiver on the www.smeter.net site because, in addition to audio, it displays an s-meter. I'd expect that location in Utah to be a heck of a lot quieter than mine here in NY, but it isn't if you only compare s-meter readings. I realize these kinds of comparisons are tricky, though, as different locations can have not only varying degrees but also different kinds of noise. |

I'll have to listen for them over the next few days, but they may be out of reach for me. There are times when I'd give my right arm for a spot that's as quiet as yours! I remember you also noting from time to time that you were hearing Bangkok Meteorological Radio....I've never been able to hear them, despite many attempts. Probably just too much noise at my location. Steve |

There are times of day and bands where the RFI waxes and wanes, and sometimes conditions are right for the really weak stuff to make it on through anyhow. It is a very unusual day, though, when the noise level is flat and the weak stuff becomes routine. By routine I mean not necessarily easy copy, but *there at all*. Usually, when my S-meter reading is low, it means that conditions on that band at that time are just poor. Often, conditions can be poor and the S-meter reading can still be high, and I attribute this to local garbage mostly. When I lived in rural New England, this latter condition never exisited...much more common here in the City. One of these days I'm going to go to battery power for the RX, and I have a hunch that this switch will help considerably. That, and getting the local 50kw AM sloppers to clean up their acts (their harmonics on frequency multiples are just harrowing). If all else fails, I will move to rural Wyoming/Idaho and solve a whole bunch of urban-related problems all at once. Bruce Jensen |

When I lived in rural New England, this latter condition never exisited...much more common here in the City. I thought that variation over the course of a day in which bands are noisy and which aren't was just inescapable and largely a function of atmospheric noise. Sounds like I should try rural New England! I used to live in Nevada, outside of Reno, fairly far removed from sources of RFI, but found things to be not much better there than they are for me now. Of course, Nevada probably counts as a "weak signal area". That may have contributed to my sense that things were 'noisy' in NV. And then there are all those neon signs on the casinos--the RFI from those probably travels all over the place.

Another thing that helps with the AM stations is a good high pass filter. I use the one from Kiwa, even though most of my receivers have solid front ends. Steve |

It obviously works - it drops the signals on the AM stations rather dramatically, and helps a bit on the resulting intermod products - and I use an attenuator as well. However, the HP Filter does not drop the levels of the 2nd/3rd/4th/5th harmonics off their dirty transmitters, as those actually radiate at the higher frequencies, which the HP filter does not affect. Thanks, Bruce |

Thanks, Bruce I haven't used the battery for a while. The antenna I usually use is a Wellbrook, and I always figure that whatever benefit derives from powering the receiver from a battery will be mitigated by having the wellbrook plugged into an AC line. I guess I need to buy another battery and an inverter. |
