hi i am trying to decode this radio but the eeprom will not read i am using a joule a400 i think it may have to be read out of circuit any ideas much appreciated the eeprom is a 93c46.

These rarly give problems unless the data is corrupted inside the eeprom.

try writing to it, if that fails i'll send you a dump file for your radio.

thanks jibes thats what i thought but i have tryed another 2 units and they are the same,checked probe connections etc all seams fine i just seam to recall a post on this subject and i thought you might have to remove eeprom and read it of circuit thanks

You probably have connection difficulties with the probe not aligning with the chip pins. Switch off the power to the decoder and power up the radio. The standby led on the decoder should be on. If not try to reposition rhe probe and push down on the chip to make contact. I find the pins on th probe after a bit of use receed into the plasic moulding sockets and have to be pushed forward with long nose pliers.
