If you need more flexibility, use the fractional generator/divider: Download File. Copy Code. clockgen .setupMultisynth (output, SI5351_PLL_x, div, n, d); For the output use 0, 1 or 2. For the PLL input, use either SI5351_PLL_A or SI5351_PLL_B.i2c_Si_VFO. Si5351 library from NT7S. Uses the updated version of the library (master). UNO and 328 boards: Encoder on pin 2 and 3. Center pin to GND. Leonardo: Encoder on pin 0 and 1. Center pin to GND. The pushbutton goes to pin 6 to set the tuning rate. Pin 7 is the RX/TX pin.Feb 14, 2016 · Click! Shop order. from. $33. The VFO/Signal Generator kit includes a Si5351A synthesiser module kit and rotary encoder. Optionally it can also be used with the OCXO/Si5351A synthesiser kit. The kit supports the full output range of the Si5351A, which is 3.5kHz to 200MHz according to the datasheet (but appears to work fine up to 292MHz, though ... Apr 27, 2017 · LZ1DPN-CW2 QRP Transceiver with Si5351. QRP transceiver LZ1DPN-CW2 for 3.5, 5, 7, 10 and 14 MHz CW operation. This transceiver is based on Small Wonder Labs SW 30/40 schematics. I also use parts from my other projects - EK1A homebrew copy LZ1DPN-CW1, with some changes in schematics and source code. This is 5W QRP transceiver.

Si570 Si5351 VFO QRP.BTW the RF amp stage will have a gain control. The last piece will be the LO and we are looking at a conventional Analog VFO (shudder), a crystal mixed heterodyne VXO and finally the Si5351. The Si5351 is the most desirable in a configuration where this is turned into a SSB transceiver as it can supply the LO and BFO all from the same board.Sep 07, 2017 · BTW the RF amp stage will have a gain control.

" This VFO is for advanced user who familiar with Arduino programing ". The Si5351 output is a square wave and I plan to fit a Low Pass Filter (LPF) on the output of mine to better suit the application perhaps. Right now I don't know exact levels required for the VFO signal. UPDATE July 14th 2019:-the existing FT-7 VFO output level is about 120mV rms. I actually have my own design Si5351 board.
