Yaesu FTM-400DR Microphone Extension
Picked up a FTM-400 for use in the shack and quickly concluded that I did not care to have the transceiver body near the operating position as would be mandated by the length of the stock mic cord.
The factory mic extension cable is crazy expensive so I began to poke around the net for alternatives. What I found only partially filled my needs I wanted a solid jack which I could mount in the shack.
As Yaesu uses a RJ12 6 conductor setup for the mic, finding off of the shelf telecommunications parts to extend mic jack was not a problem.
I shopped around Amazon.com and ordered the following piece parts. All in the parts were less than $15. And will provide a solid remote jack and in my case 7 feet of cord to remote locate the transceiver body.
- Split type 31 ferrite choke from my parts bin. Sourced from Arrow Electronics.
Attach cable to keystone jack, insert into keystone surface mount and secure cable with supplied tie.
Apply an RFI choke for good measure
Pat yourself on the back, another successful shack project.
