This 11-band All-Mode QRP transceiver is manufactured in Europe and combines SDR / DSP “Direct Conversion” technology with ease of use.
The device does not require a computer to operate, has almost all the characteristics of a “large” SDR transceiver and is thus particularly suitable for demanding QRP
and portable radio operators. The future-oriented RX is equipped with all common DSP functions, eg user-definable (extremely steep) filters,
noise reduction (NR), noise blanker (NB), adjustable AGC timecost, and audio equalizer.
The built-in BANDSCOPE shows 24 Khz above and below the QRG and also works with TX.
An outstanding feature is the “differential ADC” or “differential DSP”
It provides very low noise on reception, which is particularly noticeable on the lower bands 160-40m.
The SKY-SDR transceiver is also characterized by a clean TX.
It comes with hand-held microphone, voice processor, audio equalizer, VOX, SWR & Power Meter, built-in keyer (A / B mode) and dual-mode CW (CW / CW reverse).
AM, FM and DIGI modes are also supported.
The device has a USB CAT port (with FTDI), LINE IN / OUT for DIGI Modes, and an I / Q output for computer monitoring.
Perhaps the only QRP radio with built-in band scope.
This and other unique features make it the most interesting QRP radio in the world.

Tested at night on 40m with QRM from BC stations. All controls set equal. Identical speakers. Antenna switched A/B. Keep in mind that I can fiddle with settings and make both rigs sound almost identical so this doesn’t really prove an... Read more
