That worked for me using the old boot loader and yes the ten turn removed those annoying clicks. Now I find when getting close to the end of the tuning range the frequency gallops.. did I read that the addition of a component to each end of the pot cured this? I have also added the push button to enter settings menu and extended the frequency range ... 1.28.1 certainly makes it much more useful... a worthy companion of my UBITX... now I use that whilst continuing with my Jackal conversion..?

Hi, been reading some of the topics here and yo are all very advanced for my build. I am only just starting so need some help please, I hope to add some of your mods later.

I have a BITX40 and it has a ticking when I tune the frequency. I have read that a fix is added by replacing the 1 turn pot with a 10 turn. This also needs changes to the sketch in the arduino.

I have downloaded the Arduino IDE and the new sketch,?raduino_v1.28.1. The problem I have is when compiling the sketch. I get the error ,?

Not used: C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.21.0_x86__mdqgnx93n4wtt\libraries\Adafruit_Circuit_Playground

exit status 1

redefinition of 'struct userparameters'?

I think I have added all the required libraries but this will still not compile. I can see the problem is possibly in the name changes of definitions, but this is as the sketch has been modified by so many and not rewritten. should still work but what have I missed?

any ideas please? I know you are all way ahead of my build, but until I complete this and so learn from this, I cannot start your mods or mods of my own. Please any help given will be most welcome.
