MFJ-1278B MULTI-MODE BASIC OPERATION
Be sure to remove the jumper from JMP10 after you complete this "Connecting and
Disconnecting Exercise".
Digipeating
You may wish to have a QSO with another packet station that is beyond your direct radio
range. If a third packet station is on the air and both you and the station you want to talk to
are in range of this third station, that station can relay your packets. You set up the packet
routing when you initiate the connection. The MFJ-1278B will then automatically include
the routing information in the packets it sends.
The diagram below shows Example 1 situation in which digipeating is useful.
AD7I
/ \
N2WX ________ / \_________ K5FLU
You are station K5FLU, and you want to have a packet QSO with N2WX. There is a
mountain in the way and you are not in simplex range of each other. However there is a
station located on the ridge, AD7I, which is in range of both you and N2WX.
You direct the MFJ-1278B to set up a connection to N2WX using AD7I as an intermediate
digipeater as follows:
cmd: CONNECT N2WX VIA AD7I
You can specify a routing list of up to eight intermediate stations. Consider Example 2
below, as a modification of Example 1 above:

N2WX ________/ \_________ K5FLU

KV7D. . . . . .NK6K
AD7I has turned off his station, but you can contact N2WX by going around the mountain
through NK6K and KV7D. This time you issue the connect command like this:
cmd: CONNECT N2WX VIA NK6K, KV7D
You specify the digipeaters in the order you would encounter them going from your station to
the station to which you wish to connect.
Your station can also act as a digipeater for other stations. This does not require any special
