The (wideband) waterfall display is already in > decibels - just place the cursor at the position you want to measure. > If that doesn't work, go to Options/Visualisation/Informations on > Mouse position. For noise readings I would increase the averaging > (Avg) function to perhaps 16 or more to get a flattish line. > As a guide, I find that DCF38 is typically 63dB above daytime noise. > You are a little further away from DCF, so you should get a slightly > lower figure. > Mike, G3XDV > ========== -- Best regards, Chris 2E0ILY mailto:chris@chriswilson.tv
