Hi Art, The aftermarket programming cable I has was sealed in some type of potting material that I didn't want to bother with. I have built the clone unit from the rusky web page diagram with good results. I will say the adapters put out more broadband rf noise than anything I've seen going back to my trs-80 model one computer.
Using the aftermarket and (unshielded) clone board hoses up every broadcast radio in the shop. I started stocking the original Kenwood programming adapter and haven't needed to do the clone adapters any more. As mentioned in a previous post, the mic jack changes size from various models. I make a very simple telco jack plug adapter that allows me to use the large adapter plug with smaller jack/plug radios like the tk-840. One other oddball is, the after market programming adapter requires a 9 volt battery to function. The original Kenwood units are powered directly from the computer data lines. cheers skipp025 at yahoo.com > [EMAIL PROTECTED] wrote: > Skipp, make sure the aftermarket cable > has the jumpers between DSR/DTR and > RTS/CLS on the computer end.
