WHY ANOTHER QRP RADIO ?

With so many QRP radio's "Made In China",

why design another one in Europe ?

The answer is simple:  

Try using these Chinese QRP radios with a good antenna

on 80 or 40 meters at night  here in Europe and you will

see why something more is desirable.

The Elecraft  KX3  is a good little radio but has a high price tag here in Europe.  Same for the KX2.  We believe there is a need for a more "affordable" high-performance QRP radio in Europe.  The SKY-SDR was designed to fill that need.

The SKY-SDR's low noise,  high dynamic range  front end won't crunch, even if you turn on the preamplifier on 80

or 40 meters at night.

The SKY-SDR has most of the  DSP features  of larger hf

transceivers - direct conversion,  razor-sharp-adjustable filters, noise reduction, noise blanker, audio equalizer,

etc. and even a built-in bandscope that works on receive and on transmit.   Its clean transmitter has a speech processor, audio equalizer and even comes with a hand mic at no extra cost.

Though designed for high reliability, occasionally Murphy can visit any radio, regardless of make or model.  

The SKY-SDR is:

• Designed here in Europe
• Built here in Europe
• Sold here in Europe (by Appello-Funk)
• Serviced here in Europe - - - sorry Murphy!
• but priced [almost] like a Chinese radio!  :-)
