Re: Erratic tuning with my new uBitx
toggle quoted messageShow quoted text
You have given the opportunity to add another great feature for uBITX Users.
I do not know about your External Filter. But I know that you are doing a great job to improve your uBITX.
If you have a spare time, please introduce your External Filter. I want to make it.
I do not have much experience with such things, so I do not know if it will be the right answer.
I think there are three ways you can solve your problem.
1.Adjust the Master Calibration.
If you use uBITX Manager, do not worry.
Before making any adjustments, uBITX Manager can back up your uBITX information to a file.
If you have a backup file, your uBITX can be restored at any time.
I think you can lower your Master Calibration value a little.
If you let me know the reference frequency (EX: 7.02Mhz, 14.03Mhz ...) you used to measure in the frequency counter, I will give you a calculation.
If you send me your uBITX backup file, I can look into it more closely.
I'll skip it, Because you measured the 150hz error clearly through the instrument.
Also, if you prefer to modify the code rather than the calibration setting, add 'calibration = calibration - 00000' to the end of the initSettings () function.
Instead of 0000, try increasing the value in small increments.
