Jack,
Got the board together , all aligned and tested - voltages good. ?
Loaded the sketch - Display looks fine.
Tuned the VFO and display frequency moves.
Some observations / issues are:
Every time the display voltage updates, it flashes the screen and makes a" tsssh" sound on the speaker.
I have a 12v regulated and highly filtered power supply which i use on all my bitx40 and it sounds good - so not ?the power supply.
Cant find anywhere to select the frequency time stepping.
Which connection is used for the vfo input to bitx40? ? out2? ?SQR?
I tried them all and get the most noise from out2?
In the picture of the rotary encoder, (i used the same one) I notice some capacitors and 1 resistor? looks like a 10k
The encoder seems to work well without them but was wondering why you had the extra components, and where are they connected and what the values are?
All is off to a good start, just working thru it paces..
Thanks
