"brrrraaaap" on his speaker. As your message is displayed on his computer, his
radio will be keyed for an even shorter time and you will hear a "brraap" on
your speaker. This is the ACK, or packet acknowledgment coming back. The
MFJ TNC takes note that the packet was received correctly, but nothing is
displayed on your screen.
Digipeating
Now that you are on the air, you and your friend can try out the MFJ TNC 's
digipeating capabilities. This is actually more interesting if you have at least
three stations participating, but you can get the feel for it with two stations.
Return to Command Mode and disconnect from the other station:
<CTRL-C>
cmd:DISCONNE
*** DISCONNECTED
Now issue the following command.
cmd:CONNECT K5FLU VIA WB0QRP
As before, substitute your call for K5FLU and your friend's call for WB0QRP.
You are requesting a connect to yourself, as you did before in digital loop-back
mode, but this time you are using a sort of RF loop-back. You transmit packets
to your friend's TNC, which relays them back to you. When the connection is
established you will see
*** CONNECTED to K5FLU VIA WB0QRP
and you will be in Converse Mode. Your friend won't see anything displayed on
his computer and his TNC's state won't be affected at all by your QSO. In fact,
your friend could issue this connect request,
cmd:CONNECT WB0QRP VIA K5FLU
and you can carry on two separate conversations completely independently.
Monitor the radio transmit indicators and listen to the speaker audio. See if you
can follow the packets and the acknowledgments back and forth.
