Title: CW Key Jack for Yaesu 817ND
Post by: KB6OIN on August 14, 2008, 12:12:09 PM
Yaesu says I need to use a key jack that is 3.5mm and also 3 pin for cw. I called HRO in Oakland and they said they don't have one, but I could use a stero jack, but, "its only with a 2 pin" , so no help from them. Where do you find a jack like this that Yaesu recomends, ( better yet, already connected to a cable)??? Yaesu also said I could use a "normal" set of ear phones for a IPOD for the earphones. What do you all use??? Thanks, Iam trying to get this new rig all set up for use for a camping trip real soon, 73,KB6OIN

The standard stereo headphone plug is 3.5mm and 3 conductors -
two channels plus ground.  (Unless you have the older
1/4" size plug, of course.)  Sounds to me as though the
guy from HRO either didn't know what he was talking about,
or couldn't communicate well.

I would expect that you could find plugs and/or cables
at Radio Shack or any audio store or electronics distributor.

Yes.  No need to purchase anything special...just go to any electronics shop and get a 1/8" stereo plug (or a cable with said plug installed).

iPod headphones will work fine; but, if you don't own an iPod, they're expensive for what they are.  I don't like the in-ear headphones, so I usually use a Pro-Set with a 1/4-1/8 adaptor.

Radio Shack sells both, 1/8" (3.5mm) stereo and mono plugs:

1/8" Stereo Phone Plug (2-Pack)
Model: 274-284  |  Catalog #: 274-284

$3.99

1/8" Mono Phone Plug (2-Pack)
Model: 274-287  |  Catalog #: 274-287

$2.99

I recommend getting both.

You want the three pin, the 2 pin plug just shorts out and constantly keys the transmitter.  Sounds like you are not comfortable soldering, so you could just get an audio cable with the plugs already on and cut off one end to attach the key.
