Not to beat a dead horse and I'm sure that I've asked this question before.
I just can not find the related answer.
While I understand USOS, I can't differentiate between sending and receiving
USOS. In other words is USOS employed only by those transmitting, only by those
receiving, -or- in combination?
It is simplistic, such as:
Sending Station Receiving Station
USOS off USOS off
USOS off USOS on
USOS on USOS off
USOS on USOS on
Or does it lead to these sixteen possibilities:
Sending Station Receiving Station
USOS TX off USOS RX off USOS TX off USOS RX off
USOS TX off USOS RX off USOS TX off USOS RX on
USOS TX off USOS RX off USOS TX on USOS RX off
USOS TX off USOS RX off USOS TX on USOS RX on
USOS TX off USOS RX on USOS TX off USOS RX off
USOS TX off USOS RX on USOS TX off USOS RX on
USOS TX off USOS RX on USOS TX on USOS RX off
USOS TX off USOS RX off USOS TX on USOS RX on
USOS TX on USOS RX off USOS TX off USOS RX off
USOS TX on USOS RX off USOS TX off USOS RX on
USOS TX on USOS RX off USOS TX on USOS RX off
USOS TX on USOS RX off USOS TX on USOS RX on
USOS TX on USOS RX on USOS TX off USOS RX off
USOS TX on USOS RX on USOS TX off USOS RX on
USOS TX on USOS RX on USOS TX on USOS RX off
USOS TX on USOS RX on USOS TX on USOS RX on
Yeah, I'm confused.
Can you set me straight, Chen (or anyone else)?
Thanks,
de Phil - N8PS
