Bill, I'm running a capture to the web of your signal this evening. It is updated every 15 minutes, and the latest shot can be seen at: http://webpages.charter.net/w1tag/cap-1.jpg I have removed my preamp, and inserted a 20 dB attenuator, for a total of 50 dB of signal reduction. It doesn't really simulate long distance reception, but may be useful. John Andrews, W1TAG
