A note -
I have a RIGBLASTER PRO as stated (as well as pk232 and cp-100)...
1)...Using the RIGBLASTER PRO, I can key radio (power out all the way off) and, for example, on RTTY, which has the "diddle" which is turned on, I get only a carrier (no "diddle" sound)...
2)...Tuned to the same freq as the icom 730 is my "901" which is 4 inches from the icom and showing a "6" on the "s" meter...I hear no diddle.
3)...I did same in cw mode and radio will key but, pretty much as above....
4)...It is "reading" ok once I tune cw...
5)...Last night was the first opportunity to see FLDIGI in english and admittedly, still don't comprehend much of it....
6)...Why no cw audio such as one might hear and, no cw diddle?
