Anyone using lightweight Plantronics headsets with the Yaesu FT-897D?  How was connection accomplished?

They work passively, but no cigar. And, you still have the cord! If you go this way, you might consider making an interface box so you don't destroy the headset in the process.

You might also consider the http://www.rpf-comms.com/ Bluetooth adapter, and a Bluesonic or Blue Parrot headset. Easy interface, parings a snap, and the audio quality is as good or better than the stick microphone.

Thanks K0BG, i'll investigate.  I do plan to use the lightweight headset in a base environment... not mobile.

Plantronics headsets need a bias voltage to operate.  Pull voltage from off one of the mic connector pins, make an interface box using a blocking cap and resistor, and go for it....

Most Plantronics headsets use "talk battery", so plan for DC bias.  AND... don't forget the PTT switch, you need to plan for keying the rig! (This is often overlooked when adapting headsets).
Good luck with the project!

Joe,

What resistor and what cap? How did you wire it?

That maybe helpful to some of us in the future.

Here is how I solved the connection of lightweight Headphone/Mic to the FT897D (thanks to the Elmers out there)...

1.  a 2.2k ohm resistor from the FT897D's pin 3 - 5v output, to the ring contact for the headphones.  

2.  a 10 microfarad cap from the FT897D's pin 5 - Mic output, to the tip contact for the headphones.  Note, if using a polarized cap the + is facing the Mic output.

3.  Mic Ground from the FT897D's pin 4 - connects to the sleeve contact for the headphones.

4.  Pins 1,2,6,7, and 8 (Down, Up, PTT, Gnd and Fast)are ignored.

Again, thanks to all of you who gave advice.

 Smiley Thanks so much Joe for posting that information.  I've been looking for this information for some time and have spend monies on other headsets that stated that they would work with the FT-897D but didn't.  73's KJ4TVL

Hi All,

Some updated links to replace those featured in a much earlier post on this thread.

I have used Plantronics parts. Ignore the interface box and just use the headset. It's electrically the same as any other PC type headset with electret mic. Except it has an acoustic extension tube to the mouthpiece. Just put new connectors on the end of the cable.
