Rapidly type a string of 15 to 20 carriage returns <CR>. This will cause the MFJ-
1278B to send a continuous string of unconnected information (UI) frames. Since this
will be a relatively long burst of packet transmission, the potential receiving station will
have plenty of time to tune your signal in. To a receiving station this will appear on his
screen as:
YOURCALL > CQ:
YOURCALL > CQ:
YOURCALL > CQ:
YOURCALL > CQ:
YOURCALL > CQ:
.
.
.
.
One for each carriage return you typed.
Even a station which has no tuning indicator can eventually get you tuned in using this type
of signal as he can tune around and watch his screen to see where printing is effective.
If you are meeting a friend on a schedule, you just set the "UNProto" field to "HISCALL"
and do the same thing. When your friend finds you, this will appear on his screen as:
YOURCALL > HISCALL:
YOURCALL > HISCALL:
YOURCALL > HISCALL:
.
