Receive Practice Mode
Figure 11 – Receive Practice Display
Random five letter groups are sent continuously until the user either pauses or ends the session. The
content of the groups is governed by the level set in the Practice Setup Menu. Test progress by hiding Tx
and then copying some number of lines. When done, press
INSERT
,
TAB
, and then
PGDN
to go back and
review what was sent and compare to what was copied. Resume by simply pressing
INSERT
.
Echo Practice Mode
Figure 12 – Echo Practice Display
The K45 sends a list of letters from the selected level and the user must repeat them accurately either by
keyboard or paddle. Each trial starts with a single letter and progresses to a group of five letters by adding
one letter at a time. If the user successfully echoes all five strings, the K45 will send
AR
and then start with a
new group. If the user fails, the K45 will send eight dits and repeat that group until the user gets them all
correct.
INSERT
,
TAB
,
PGDN
and
PGUP
are very useful here just as they were for Rx practice.

Figure 13 – QSO Practice Display
A basic interactive QSO experience is presented to the user. The K45 starts off with a CQ which the user
responds to. Exchanges will continue back and forth simulating an actual on air QSO.
Callsigns, names, locations, etc. are fictitious and generated at random. The K45 is very unforgiving when it
comes to letter and word spacing. If words or letters are run together, they will be ignored, and progress will
be very slow. The user can choose to use the keyboard or paddles to respond. When using the keyboard,
be sure to put a space after the
K
,
KN
,
SK
, or
BK
at the end of an exchange. This will help the K45 will
detect the ending quickly. If this is not done, the K45 will still respond but only after a somewhat long timeout
delay.
A full response to the initial CQ is expected
and must include the calling station’s callsign followed
by
DE
and your callsign. If you don’t get this right the K45 will respond with a QRZ.
For example, in response to
CQ DE W1XYZ K
, I would reply
W1XYZ DE K1EL K<space>
After the initial exchange, The K45 will respond to
BK
if you don’t care to enter a full exchange on every go
‘round. To end a QSO early respond with either
73
or
QRT
and that will speed things along;
TIME TO QRT
or
WILL SAY 73
works nicely. The session can be paused with the
INSERT
key or aborted by the
ESC
key.
To review a session, press
INSERT
to pause and then use the
PGUP
and
PGDN
keys to scroll around the
text. When the
INSERT
key is pressed a second time, the K45 will resume where the session left off.
Depending on the timing of the pause, the K45 may ignore or repeat the last exchange.
