INTRODUCTION
The Aerial-51 SKY-SDR 11-Band,
All-Mode transceiver is a synthesis of
modern SDR/DSP technology and
ease of use. It sports nearly all of the
features of much higher priced SDR
transceivers, has knobs, is easy to
use and requires no computer for
operation.
The SKY-SDR comes with advanced
DSP features such as user-definable
razor-sharp filters, Noise Reduction
(NR), Noise Blanker (NB), Notch Filter
(NF) and adjustable AGC timing.
BE CAREFUL when using the
radio. A false adjustment of some
parameters may lead you to
believe the radio is broken!
RESET: If you think the radio may
be misadjusted, you may reset
most parameters simply by
entering the Service Mode, and
then immediately exiting the
Service Mode. See Page 24.
The SKY-SDR also incorporates a
BANDSCOPE which displays 24 kHz
above and below the operating
frequency. This helps find stations on
a quiet band, or locate a free spot on
a crowded band.
SKY-SDR’s5 Watt transmitter
comes with a hand mike and produces
one of the cleanest signals on the air.
It includes features such as Speech
Processor, Dual-Mode CW/CWR,
built-in Keyer supporting A/B modes
of keying and full metering of output
power and SWR. External amp
keying is available through a
dedicated RCA Phono (Cinch) jack.
The SKY-SDR has audio equalizing
for both RX and TX modes, RIT and
XIT, and of course dual VFOs. It
includes a USB CAT-Control with FTDI
decoder, and LINE IN/OUT for digital
modes.
SSB Mode requires pre-adjustment
of the speech processor and TX
Equalizer for good speech quality.
