And sometimes, what works today, may be totally silent tomorrow. That's from experience. Look up "Monitoring Times" on the web (also a *great magazine" for the hobby). One list on their sight is the *Hot 1000* IIRC. I'm not familiar with the E5. Does it have SSB (single sideband) capabilities? If you get the Monitoring Times magazine, it has a section that goes hour by hour for 24 hours, listing broadcast stations in English on shortwave. Sort of a TV guide for shortwave. Welcome to the world of Shortwave Radio. If that radio has SSB, you can get Ham stations, Utilities (ships, planes, etc.). On AM there is the Broadcast Stations, some Ham, and CB. And it goes from there.... My first station, many years ago, was Radio Australia with a 30 foot hunk of wire just thrown on the roof. (Didn't know it was a powerhouse station then), but what a rush hearing that accent, and knowing it was from a different part of the world. Again Welcome!!! Hope you find most of us friendly and helpful. And just remember, the *only* stupid question is the one *not* asked. I've seen questions here that I didn't know the answer to and was glad someone asked, because it got me learning new things. So ask away!!!! Happy Listening, Eric Thanks Eric. The E5 does have SSB. So here's one of many dumb questions to come. If I have SSB do I also have LSB and USB? Yes. I've read the definitions of both as well as SSB but am still a little unclear. For example, a listing I have from DXing.com reads: "This band is mainly used by aeronautical stations in USB." Is the single-sideband capability referring to the fact that I can receive just one "side" of the carrier wave, either USB or LSB, and filter out the other side depending on which "side" is actually carrying the signal? Snip The word band has a different meaning depending on context. When speaking about SSB, USB, LSB the inference is a range of frequencies below (LSB) and above (USB) a stations carrier frequency. This range of frequency is defined by the information that modulates the carrier and so it is a small range of a few kilohertz wide. Here USB and LSB are the sidebands of the carrier. When speaking about a range of frequencies that by regulation are used for a specific purpose such as aeronautical communications is a wider range of frequencies that will accommodate many carriers or stations and is more like 100 to 500 kilohertz in width. Stations that broadcast in SSB mode usually only modulate one sideband upper or lower. If your radios has a switch for USB / LSB then you will have to pick the correct sideband to hear it. If your radio does not have that switch you just turn the BFO control in one direction for USB and turn it in the other direction for LSB. -- Telamon Ventura, California |
