I use my FT-60 as a mobile rig sometimes. I clip it to a sturdy plastic drinking cup set in the cup holder. Part of the cup is cut away for ergonomics. Works trick. Simple. Cost effective. But the location is just out of reach with the standard FT-60 speaker/mic curly cord. So I needed an extension. Four contact 3.5mm m/f extensions are not everywhere. Had to do some looking. Some success. Some fails. FYI. Heard of these same trouble from others. First I ordered an 18" Cable Creation brand. Worked fine. So I ordered two more for some friends with same radio. Those two were fails. Intermittent unwanted TX. Would not stay in position properly. So Cable Creation was 2 of 3 fails. Then I ordered two additional different ones. Had to go a bit longer. First was made by Dukablel. Wow. This thing looks well made! Plugs in and works pretty good. No issues so far. A bit stiff though on account of the rugged woven outside. With that I ordered a Startech.com brand just for comparison. 3 foot length. Right suppleness. Not too stuff. Plugs in great. Seems to be the least fussy of all of them. It gets my vote. These are all in the $7 range. (Additional tip is to run the mic and power cable under the belt clip up near the hinge to assist in strain relief etc) Mobile operating is easy and comfortable with the mic and extension, the power adapter that plugs into car power, and the Comet CA2X4 SR antenna mounted on the Jeep's roof gutter. (Old School. Old Jeep). Lots of antenna gain. 5 watts works like 15! Simple, effective, good quality mobile rig that fits.
