Hello,
Using a WinRadio Excalibur.
I have noticed that for quite a few foreign am stations, the best reception I can get is
when I use lsb, or usb, rather than the normal am (for normal am here, the bandwidth encompasses the whole signal). A very significant improvement, generally.
Why is this ?
And, am I correct that for the daylight hours (mine), the frequencies around perhaps 20 to 30 MHz "usually" have better propagation than the lower ones around, e.g., 5 to 10 MHz ?
And at night, it is generally better at the lower frequencies ?
Thanks,
Bob
