FT-817 Power Connection

I’ve seen a lot of discussion on the Internet lately about the FT-817’s less-than-robust DC power connector. Its miniature coaxial power connector has long been recognized as a failure waiting to happen. I thought I’d chime in with my crude, little hack.

Over the years, users have come up with a variety of ways of dealing with the FT-817’s power connector. If you’re brave enough, you can just hard-wire the power cord directly to the FT-817’s main circuit board and eliminate the connector altogether. You can also buy a really slick adapter that gives you an Anderson Powerpole connector on your FT-817.

When I bought my FT-817 almost 15 years ago, I was immediately leary of the little 4.0 x 1.7 mm power connector; there was no way it was going to hold up in the field. I didn’t know of any commercial options at the time, so I raided my junk box to come up with a solution, albeit a crude one.

I merely attached a small right angle lug to the FT-817’s ground screw. Then, I used a couple of small nylon cable ties to secure the power cable to the lug and provide some strain relief. I installed Powerpole connectors on the other end of the cable. It’s not pretty but it served the purpose.

Although my FT-817 doesn’t see as much field use as it used to, my stupid-simple hack is still going strong after 15 years. While this approach doesn’t eliminate the FT-817’s little DC connector, it has (so far) survived many years of portable use in the field.
