In fact, that's exactly what it is. Hambuilder will continue to business as usual as long as government regulation allows. VU3XVR Si5351 DDS VFO BITX40 CW Modification. Software sources are listed at the end of the demo. You can reach the menu functions by pressing the right encoder. In fact, if I use an SMD version of the ATtiny85 and the standard si5351 chip, it’ll all fit on the back of the compact 16 x 2 alphanumeric LCD. 45 - 210 MHz - output is CMOS Square wave; Kit B supplied with Si570BBC - covers 3. This has been kept as simple as, any bufffering, amplification or filtering is left up to you to build to suit your purposes. 2MHz to 58MHz 90 deg phase output Si5351 Adafruit development board with Arduino Nano + LCD display Below is I/Q phase accuracy measurements with different frequencies.
