On page 13 under MIC the manual references the MAIN:MIC SRC menu entry. However the menu listing on page 52 doesn't list this entry. It does list MIC SEL. Are these one and the same? Also, if you operate voice with a mike and PSK or AFSK using LINE IN do you have to change MIC SEL each time you switch from one to the other? 73 de Terry KK6T
