Ladies and Gentlemen I respectfully request that each of us take a moment to read page 50 in ARRL's QST magazine, December 2007 edition.
It addresses signal quality of digital transmissions using the PC soundcard, and how to avoid over-driving the signal. Overdriving causes spallter and occupies unnecessary bandwidth. Specific, simple detailed steps are provided. Terrific explanation and great info! Please share this with other hams, new and old. Some of us (myself included) have made mistakes in the past. While these were made out of a lack of knowledge/skill, it is the responsibility of those more experienced in our hobby to share and help educate others. The result will be more proficient operations by all, through cleaner signals and proper operation of our equipment. If you do not subscribe to QST, I would be happy to share the summary of the article (without violating Copyright).
