Radio hardware is helping "break" SW ...

Speak for yourself. For me, the biggest problem with shortwave is manmade noise. And has been for about the past 20 years or so I've been living in big cities. Being able to hear anything more than the half-dozen or dozen strongest signals means getting out of town. I'll be damned if I have to take a computer with me camping (and then bother with shielding it so I don't have to hear the sort of RF crud I just drove out of the city to get away from) as well as a radio set. Oh, and then there's the extra power consumption (remember, I'm using batteries out in the woods) of a computer just because a radio doesn't have a front panel anymore. Plus, I can't see having to fiddle with a mouse pointer on a picture of a tuning knob as any sort of improvement of having a real tuning knob to turn. -- David Barts Portland, OR Receivers having a single conversion have the lowest internally generated noise ,I believe. It may be possible to have SDR with better performance,eventually one day. Actually,any receiver having an oscillator generates birdies. A PC or a laptop generate more RF than the Woodpecker transmissions from years ago. |
