Raj's response seems to be more on target, post 46601
Also Dexter's post about filtering the 12v power supply line to the Raduino.
This may be firmware issue but I doubt it.
The original firmware for the Bitx40 as shipped did not have a problem with tuning ticks.
About a year ago, the Etherkit library was changed to reset the si5351 PLL whenever the frequency changed,
and that definitely caused clicks when tuning.? If you happened to update firmware within the month or
so time period when the problematic Etherkit library was out, then yes you may have firmware
that is causing tuning clicks.? As of last summer, Allard's code no longer uses the Etherkit library.
Regardless, it's a very good idea to update your Bitx40 to Allard's latest firmware.
I'd recommend the v2 firmware, though it does require a few simple hardware mods
that Allard's v1 firmware does not need.? ?
