The circuit design for the AGC can become rather involved as different time constants within the AGC loop may be required to provide the optimum control for different types of modulation: AM, SSB, etc.These are just a few of the issues that should be taken into consideration during the RF ...
K1JT has chosen to present a S/N-reading based on SSB bandwidth instead of using the very narrow bandwidth that the software uses to decode the tones. This has given JT65 a reputation of being far superior to other communication protocols, but as you will see in the text below, JT65 app...
but it does away with almost all of the game elements. Another improvement is the voices used in the spoken examples. Where Duo can sound very artificial and cartoonish, Busuu uses actual people speaking naturally. My comprehension has improved...
