How do you do the system design if you haven't figured out the path mechanisms yet? The advantage of crude CW methods is that effects like doppler and dispersion are readily apparent.
For example, by listening to some tapes, it wasn't difficult to determine that 10 GHz signals were being distorted by some windmills in Princeton MA--at least by those of us who have attempted to sleep near those noisy monsters.. Zack W1VT
