Signal quality on a scale from 1 to 5

TX:RX

1: connection established but no discernible coms.

2: possible to understand but the listener cannot tell if the voice is male or female

3: decent coms, static and distortion occasionally, may include echo

4: Good coms, maybe some static in the background

5: Perfect coms

TX side and RX side

4:4 was the tactical mark to hit.

but this is ancient history… digital age and all
