Hello, The charts for receivers are very useful! Yes something similar for digital modes would be interesting with some columns as: speed in wpm, bandwidth, mode (PSK, FSK...), robutsness (FEC or no FEC correction), average power/peak power ratio, S/N minimum (under gaussian noise), sensitivity to QRM, QSB, ionospheric Doppler modulation and so on.

You have taken us closer to the goal of 100%. :-) Perhaps someone can build on the start you have made and create a spreadsheet or database or something that makes it easier to compare modes. Sherwood Engineering has a chart they created for comparing Amateur Radio receivers, perhaps we might follow their model. http://www.sherweng.com/table.html <http://www.sherweng.com/table.html> -- Thanks! & 73, doc, KD4E ... somewhere in FL URL: bibleseven (dot) com [Non-text portions of this message have been removed] Need a Digital mode QSO?
