"Honus" wrote in message . ..
I posted this message over in rec.radio.amateur.dx, but no one seems to have any answers for me. It's perhaps a little off-topic, but since most of the posts in these parts are, it'll fit right in. And at least here I'll get some sort of response. Even if it's political. I'm just going to cut and paste: I'm new to the hobby, so please bear with me. I picked up a Gene Scott broadcast last night on MW at 1615 KHz. Here's the Anguilla, British West Indies 24 hours a day - 7 days a week 690 KHz AM 1610 KHz .........snip..................................... ......................... The DX 350 is a sensitive receiver but it doesn't work too well with a long antenna. The circuits overload and you find images of stations in all sorts of places where they shouldn't be. The first thing to do is to disconnect the long wire antenna and see what kind of reception you get off the whip. Probably the "ghosts" will disappear. Another thing you can do is to find the switch on the right hand side of the radio marked ""SW LPF" and switch it on. This will help remove some of the mysterious signals. If the problem persists disconnect the ground and see if that helps. You may find that you can receive most of the stations you want right off the whip. Also, the "RF Gain" contol should be turned counter-clockwise to the point where the stations just start to drop off. If you wnt to get some of the weaker stations, you will have to experiment and see how much antenna you can use before the overloading starts. You can wind a few turns around the whip or use the antenna input at the back. I think 10 or 20 feet of wire would be plenty. When matched to the right length of antenna, the DX 350 should be fine for your purpose. If you get a bit frustrated at having to fiddle with the antenna, ride the RF gain, and switch the LPF on and off, remember that communications receivers that handle a wide range of signal strengths cost upwards of $1,000.......good listening.....ken.... |

Thanks for the tips, Ken. I'm going to give them all a try ASAP. |
