I know it's an older thread, but am wondering about the contents of the EEPROM on my AD2700. It differs as follows:
First dump is my AD2700 followed by the non-fixed and fixed dumps of @baho. 0x30 is the byte changed. As you can see contents are different. Calibration values?
I could just upload the code and see how the station responds. Any ideas?

Edit: I tried replacing with the 'fixed' eeprom contents, but that didn't work. I also just edited the bytes around 0x30 and that resulted in station not starting up. I put it together again, but now am wondering what was fixed 0x30 to 01 or to 00? Oh well, happy soldering
