His website has details on a DDS using the AD9850 [a close relative of the AD9851] calibrated to a GPS 1pps clock. DX Year in Review 2 months ago Romeo 3W3RR jail-pedition. Płytka została zaprojektowana tak by można dostosować ją do swoich potrzeb. Basic code to make Arduino communicate with ILI9341. Python for Microcontrollers — MicroPython Turns 7, CircuitPython 5. The GPS signal is connected to the plug to the lower left. It covers 40, 30 & 20m with tuning in 100Hz steps. Joined: 2017/05/03 - 08:22. シリコンラボラトリーズのSi5351を使った好きな周波数を出せるクロックモジュールです。 I2C制御で2. L-band Dual-GaAs FET. - add a small ublox6-GPS-system with a special digital control algorithmn to correct the thermal and absolute deviation of the xtal in the si5351 breakout board: result: a universal GPS controlled generator with an absolute frequency precision of roughly about 10^-8 (=10 ppb) (You find them on the well known Chinese delivery pages for about 3 US$. Wanted frequency. Kit includes a free metal case Station Acc: Visit SIGEN PROJECT (Revised to R1) SIGEN-0517. 5mHz—140mHz Sweep step: ≥ 1 Hz Sweep speed: ≥ 400 points / sec Point frequency or sweep output power: 10dBm. The Si5351A has a register that can be programmed to provide the desired crystal load capacitance. Both designed by Joris (KTH rf-Design). Interesting approach.
