Hi Bob W7LRD
An effective method of reporting and confirming signal reports helps in completing information exchanges .
The following system was currently in use on CW reports when I was on 432 MHz EME early 1977-1980 with an array of 16 x 21 element yagi and 1 kW
T = signal detected M = letters or portions of call copied O = both calls and report copied MT = nearly solid copy 5 = solid copy, no need for code
By this system as an example a series of OOO OOO OOO plus both calls received at both ends and confirmed with RRR estabishes a contact.
I dont know is the above procedure is still in use but if you use it be sure to be understud by the Arecibo very expert old timer EME operators.
There is a reason to use the above procedure that is avoid using code characters requiring dots such as the letters I, E, S and H and the numbers 2 to 7
By the way since we hope to receive Arecibo we will see what procedure they actually will use in real life.
If available on your receiver use the CW 500 Hz filter.
Good luck and 73" de
