Acid base problems with answers

So, I got a Si5351 board from QRP labs to play with. I got it up and running with the Si5351 object in the OBEX. But it is way off frequency. I did some fooling around with the Arduino/Si5351 and while it is a little off and needs some correction, once corrected it is spot on. Meaning that the offset is consistent over a wide range of frequencies. Before loading the firmware onto the Arduino, be sure to change the callsign (6 characters or fewer) and locator (exactly 4 characters) variables to the proper values for your station (and perhaps the dBm if you use an amplifier). Set the frequency to any one that you like within the tuning range of the Si5351 by setting the freq variable.

Hey all, I've had a few requests for Arduino code to run the ADF4351 (also ADF4350) from an Arduino. What I am posting is code that I received from Richard – OE6OCG a year or two back. He set it up to use with an LCD and 4 button controller. For my use I modified it to use a rotary encoder, TFT touch display,

Nov 26, 2019 · Last year I wrote that Arduino was so easy, but I didn’t really follow up on that. A few days ago, RC (KE6BGN) commented that he was wondering if any progress had been made on the Arduino based VFO/BFO for the BITX40. There has been, and I have made a short video for your viewing … Continue reading

Nov 21, 2016 · Ok, by popular demand, here are my project files for the Arduino SI5351A VFO. The board layout was done in SprintLayout and I do have some boards being fabbed up in China and should have them here within a week, as I need a few for my own projects. So the board uses an Arduino Nano and the SI5351A breakout board from Hans Summers QRP-LABS. If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino and a breakout board for the chip. The SI5351 is a programmable clock generator. It can output up to eight unique frequencies at 8 kHz to 133 MHz.

Hacking the Bitx40 with a homebrew Si5351 with OLED Display. Hacking an earlier version of the Bitx40 to include the Si5351 LO and an OLED Display. I purchased my Bitx40 early in November 2016 before the "Digi" VFO was available from hfsigs.com.
