I second KF7RSF's comment. Can you please tell us what the red wire /speaker connection is you are using? It's not clear on the video. Kent W9WB

Is the raduino included with the BITX pre-programmed?

Nice idea Peter! Increase in value of C96 will give you a little more range. I will try adding a parallel MV209 to D9 to increase the tuning capacitance range. I have a bunch of them in the

I downloaded the repository and installed the Si5351 library. I discovered that the sketch does not compile with the latest version of the Si5351 library, version 2. I've just submitted a pull

If you don't wish to add a DDS to the Bitx40 (eg need low current consumption) I now have an alternative. A cheap as chips 4.92 MHz ceramic resonator can be substituted for L4 in the VFO and be

Got it to compile, though I needed to download the Si5351 libraries using the following from https://github.com/etherkit/Si5351Arduino : Library Installation

Hi Todd, I have soldered RG-174 directly to both the Adafruit and Etherkit boards and had great results on the last three projects. I'm using a Etherkit board with a SMA RG-174 pigtail to connect to

Well, I got some money for Christmas so I decided to use some of that to order my BitX40. Looking forward to receiving it! RichKC8MWG

You're right, moving to class C is more than a matter of changing the IRF510 bias, will require higher gain in the preceding stage. Another thing to look into if somebody wants efficiency is class
