AVR – CTCSS 2 Tone and APRS AX.25 project.

Brother Toner Transfer to PCB working!!!

AX.25 encode is complete and seems to work well.  AX.25 decode works, but I have a special mode and also have a CTCSS listen setup to remotely turn on that mode.  Still some items to do , but its almost time to put this on a board.  If you are interested in this project please let me know.  I was able to get my Brother Laser printer to work with the toner transfer method after some trial and error.  I had great results using a Brother HL-4070CDW and Kodak inkjet photo paper using a iron and being very patient with the soak.

I experimented with several designs.  A resistor ladder, a CML modem IC, and a DAC.  They all seem to work but my goal would be to have a nice small unit I can carry around that does double duty as a simple repeater controller.   So far so good.  I went back and used both a DAC and a AKM CTCSS chip to do what i needed for dual duty.  I plan on building a version on a pcb with the CML but I want to try the newer 800 series as its pretty much an all in one device.
