as for the NAV1 encoder, these pins short out:

Hey again I was wrong about the input re-assignment, this is the new one: Input 24 BtnTRVFR 74HC165 - 1
Input 25 BtnAP
Input 26 BtnSPD
Input 27 BtnHDG
Input 28 BtnALT
Input 29 BtnNAV
Input 30 BtnAPR
Input 31 BtnREV
Input 16 BtnTR1 74HC165 - 2
Input 17 BtnTR2
Input 18 BtnTR3
Input 19 BtnTR4
Input 20 BtnTR5
Input 21 BtnTR6
Input 22 BtnTr7
Input 23 BtnTRCLR
Input 8 BtnNAV2SW 74HC165 - 3
Input 9 BtnADF
Input 10 BtnBFO
Input 11 BtnFRQ
Input 12 BtnFRQET
Input 13 BtnSETRS
Input 14 BtnTRIDENT
Input 15 BtnTR0
Input 0 BtnNAV1ASW 74HC165 - 4
Input 1 BtnNAV2ASW
Input 2 BtnMKRASW
Input 3 BtnDMEASW
Input 4 BtnADFASW
Input 5 BtnCOM1SW
Input 6 BtnNAV1SW
Input 7 BtnCOM2SW also, shift register 2 is still not working - I thought maybe I didn't cut good enough, so i made 2 more cuts, and soldered the wire from the arduino pin instead of the location in the middle, still no go. and when pressing COM1ASW it still shuts off all the 7Seg even if the wire is not connected?
Yes, same as the table above  Checked again, all the connection look good, can you please confirm the orientation of the shift registers as well as the orientation of C42 and C45  |

 now i feel stupid (a bit)- number 5 was upside down - i soldered the socket wrong and then didn't check when I put in the chip....  the other one and the capacitors are the right way.
so now COM1 does not shut off the 7Seg but it still does not work...

Can you please check one more time, in the picture you show is the NAV2. I have been going through Nav1 and Nav2 Mhz and Khz traces, they look fine, they are not shorted, maybe any soldering somewhere. |

Well by so many connections it can happen to any of us, maybe the shift register got damaged because it was installed wrong, can you use another shift register and check again. |

when checking all the other encoders they are not shorted, only these 2 pins, will try to find out if there is any soldering error

I'll try to solder another board to see if I get the same problems...

when there is nothing there they are not shortened

one more thing if it's not a big issue - is it possible to do the engraved button stl with the text at least 2 time deeper, or even more? as you can see from the image above, the letters are too shallow so when I fill them and sand a bit they are almost gone Attached please find the buttons with 1.2mm deep engraved letters/numbers. There are two attachments, in one of them there are all the buttons as a group and on the other attachment you will find only COM1 button to try out if it is ok. Please let me know if the engravings should be even deeper. Cessna 172 Radio COM1 engraved.stl (48.32 KB) Cessna 172 Radio Buttons engraved.stl (833.57 KB) Regards AlbEagle |

BTW I don't know if you remembered, but the holes for the ident button where too small, hope you fixed that too in 3.2?
and changing the text on R105 to 10K....
