The interface is only a level translator and can be replaced by a diode, transistor, and a resistor. I have made such a thing and it works very well.(see one of the later issues of 73 for a circuit) The commands that you use to talk to the interface are all explained in a book, that should have come with the interface called "Technical Supplement". If it didn't come with the radio you can get one from yeasu for $5.00 and a copy of your sales slip. If you have lost the sales slip then it will cost you $15.00. This book also includes schmetics, parts list, board layout, and calibration infor- mation. Hope this was some help. 73s Dirk KD7UB
