--------------------- Ordinary background QRN on 80 or 160 meters works FB too. Just avoid any frequency where a signal falls within the bandpass. If the background QRN is not loud enough for someone on 80 or 160 (lucky, lucky you having THAT QTH!) just turn on the Preamp. I use a noise source only when I'm in the shop away from an antenna. There's absolutely NOTHING about a noise generator in this application that makes the alignment any more "perfect". The noise source is just a convenience. At times when an antenna is not available it's a convenience well worth having, but that's all it is.
