SKY-221 SDR HF 160 -10m Transceiver
With Built-in ADC / DAC
SKY-221/V21 / is designed based on SKY-209 with built in ADC / DAC CM6206.
The original idea was for SDR Transceiver for PSK, SSTV, JT65, JT9, RTTY and other, in my testing about
3 months showed good results and also on CW although CM6206 is 48KHZ but very quiet with
layers compared to the standard built-in sound cards and Inboard laptop computer.
SKY-221 /V21 / need only a USB-2 cable to connect the PC no additional cables except the power supply
and connections between antena. Other conection with PC are only virtual .
SKY-221 /V21 / a 3 jack sockets a front panel :
1.for stereo headphones.
2.for electret microphone with PTT /not used/.
3.for plain keyer or to interface with another computer to work with program in contest
SKY-221 /V21 / AF has its own built-in 1W mono amplifier with speaker.
SKY-221 /V21 / work every program with PowerSDR ,but recommend with IQ
Transmitter power 10W types of SSB andDigital Modes with power supply 13,2V, 7W CW.
