SKY-SDR USER MANUAL Ver. 1.3.1 - 28-MAR-2017
Fundamentally, the radio has two
independent VFOs on each band and
the frequency each is tuned to before
enabling SPLIT will be its TX frequency
after entering SPLIT Mode. To toggle
between VFOs as always: simply push
[VFO]
.
IMPORTANT:
Even though one VFO
will be on the desired RX frequency,
you will NOT use it for receiving. For
receiving you must use the VFO that is
showing the desired TX frequency and
tune it manually back to the RX
frequency.
To EXIT SPLIT
at any time, simply by
push [RIT].
This will be clearer in the example
below:
SPLIT OPERATION EXAMPLE:
•
“DX1DX”
is calling CQ on 14
.
150
MHz and
requesting callers “UP 5”.
•
You are receiving on
VFO-A
.
•
PRESS
THE
[VFO]
BUTTON. The
radio switches to
VFO-B
.
•
Tune
VFO-B
to 14
.
155 MHz (5 kHz
above DX1DX’s frequency).
•
Now
PRESS
the
[RIT]
BUTTON
–
as if you were normally turning on
RIT. You notice the “
*
” appear in
the top right of the display.
DO NOT TURN THE VFO KNOB.
•
IMMEDIATELY
PRESS
THE
[VFO]
BUTTON to switch into
SPLIT
Mode
displaying 14
.
155 MHz.
THIS is
now the TX frequency.
The TX is
locked on this frequency. The VFO
knob now tunes the RX frequency.
•
Tune back to 14.150 MHz and
find DX1DX again. READY!
•
Your radio is now working split.
Confirm by pushing the Mic’s P
TT
button and watching the display.
When you transmit, the frequency
switches to 14.155 MHz. When you
release the PTT button it returns to
RX and 14.150 MHz.
•
You may switch to VFO-A at any
time and you will be receiving and
transmitting
on
14.150
MHz
(CAREFUL: if you transmit on VFO-
A, you are transmitting on the
frequency of DX1DX). If you tune
the VFO knob, it will change the RX
frequency but when you transmit,
you will transmit on 14.150.
To
EXIT SPLIT
, just push the
[RIT]
button while in RX Mode.
Practice using this feature 2 or 3 times
before you need it. You will soon see
that although it is different, it is very
easy to use!
MEMORY
The SKY-SDR has 100 memory
locations, labeled from 0 to 99.
Other information such as mode,
filter bandwidth, AGC settings, etc.
is also stored together with the
frequency.
STORING DATA IN MEMORY:
•
Tune the VFO
to the
frequency to be stored and
make sure that other settings
such as mode, bandwidth,
AGC, etc. are as you wish to
store them.
•
Press
[MEMO]
to switch to
Memory Mode.
•
Rotate the VFO
Knob to the
memory slot (0 to 99) in
which you wish to store the
data.
