Oh I read the whole thread, maybe not in too much detail, too busy building the board
Yeah, FarmTech has your name displayed on the lCD on board start up.
I just need to get the board installed in a box with pre-amp.
Cheers
well I hope it show :
Preamp Controler
V1.6c (c) Danzup
Then wait 2 sec and show
FarmTech Special
R2R Version / Shunt version
Hmm , I dont have any problems with a normal FM radio
I even have a I2C radio board on pcb (AR1010) (TEA5767 radio chip)
even weak radio stations comes in ok no MCU noice
but I have a 0.002V 50 hz hum but its ok , I can only hear it if I pump up volumt to full and no input connectet
Can you take a picture of you build so we can see how it is connectet in the case ?
I have made some code for the AR1010 modul
but only for the M16 Danzup R2R (Farmtech) EQ 2 RADIO
Still running test on this firmware .
Will make a version for PGA2310 later (when i get more freee time)
My take on this volume controller, completed 80% but its already working great 
It's attached after a NOS DAC + JBoz kinda line amp.
I plan to add in the future a B1 buffer after the controller to have lower the output impendace.
Of course there is a lot of work on the case yet. I want to paint it black and to add nice wood front and back panels. Lets see what wood my carpenter friend recommends.
Cheers!
p.s. @FarmTech: I found some bugs with the volume controller software, I will create an error list and send it to you, hope you can fix them

Two bugs, both related to direct select buttons:
1. Cannot switch to input 4 (Aux) using direct select button (I believe this was signaled by others)
2. If I switch back to 1st input (CD) using the direct select button then Power Off and input selector (Ch+) are not responding (Mute and Vol+/Vol- are OK); If I go to 1st CD input with Ch- then everything is fine. Resolution: I have to use another direct select button (DVD or Tuner) to have Power Off and Ch+ working.
Not big issues but sometimes annoying.
later edit: wish list:
In my opinion it would be better to have Power On/Off and Mute use every second/third volume step. Maybe a dedicated config menu item to setup this.
Thanks!

Yes ths I found myself Direct select input 3 & 4 have same address on port
I cant get mine to do this error it works fine after power off and then Ch+
but will check code to see if there is a problem
Note some Remote have power On/Off working as Power OFF cmd then next time you push it it send 1 same as direct input select 1 , the one I use do this anyway
I made a smal program to test remote you can see the commands in this program just look for it here in this thread back to about page 38 I think
Did you add your remote via setup new remote menu ?
I will make a update of the files later m at the moment I have to many things to do before I get to this,

Hi, Yes just got time to study them , but you write you will make a smal schematic , thats was what I was wating for
Main board AVR , clean the soildering up this can only make it better ,
check that your relay for RADIO is working ok (connect radio on other input for test)
You have alot of wires OMG , never seen one like this
Today I got post from Texas instruments PGA2311UA (smd) +-5V version
you use (PGA2310 +-12V)
so I will build a full controller board with the PGA2311 on same PCB as AVR
hope its done soon
yes i know the wiring its a bit just tooo much , i plan to reduce it but i m not getting time to make a sexy pcb, for it. such that i would have all the regulator ic , power amp chip, and pga2311A and also a 3 on one RCA jack, but then only issue that makes me make differnt boards is , cabinet fabrication, as i have access to ready made cabs of 3"h 12" w 8"D , so then cutting lcd cut out, making holes for rca sockets , is a bit tooo much ( some times a bit lazy as i have to go out and get it done, )
