Have you used Free Software (on your Mac) for either of your dongles? Which Free Software? What are the name/models of your dongles? How do you equip your dongles so that switching antennas over and over again doesn't wear out their connectors? You're blind, so you can't see those pretty waterfall characterizations of the spectrum that are given you. I assume numbers are recited to you. Which softwares do you use to make all the data numeric instead of graphic? Maybe with any luck some day I can pay you back with a particularly good software filter.
