Compare your solution with Figure 3-6.
They should be identical.
Figure 3-6. PE10 Net.
Station ZOAT appears to be calling two other stations, Y9BR and U5FC. Station Y9BR
answers station ZOAT establishing a link, but the call sign U5FC never appears as a
transmitting call sign. Instead, three other call signs contact station ZOAT. Since four
different call signs are observed calling only one call sign (ZOAT), it may be assumed that
station ZOAT is CT of the net, and that call sign U5FC identifies X8CA, W7DF, and V6EI
collectively. The order of the return call-ups appear in response to the collective call
indicates that X8CA IS O/S2 and that V6EI is O/S4.
8. Another type of general call-up is referred to as the LINK CALL. A link call is a type of
call- up in which a common call sign is used for intercommunication between two stations.
Figure 3-7 is an example of a link call.
