. Their cable is $30.00.
I have a VX-6R and a FT-7900R. I bought the 6R programming cable from AES Ham when I bought the radio and made a cable for the 7900 that connects to the non-USB end of the 6R cable. I am getting a FT-1500M from one of my Elmers this weekend at Ham Holiday in OKC, so I am on the lookout for the cable.
The cable for the 1500M is USB on one end and 6-pin RJ-11 on the other. Since I already have the 6R cable with the USB end, I might see what it would take to make a 6-pin end.
Universal Radio has the cable (w/ software) for $37.95 + S/H.http://www.universal-radio.com/catalog/fm_txvrs/2736ops.html
Of course, AES Ham has the cable AND software together for $39.99 + 4.99 S/H. That's another viable option.http://search.cartserver.com/search/search.cgi?cartid=a-6994&category=newprices&maxhits=600&keywords=FT1500M&option=sm3&go.x=9&go.y=12
