Kx2 questions

Jim Nestor
Just got my KX2 with ATU & internal battery. Waiting on my paddles. Have a number of power sources & antennas to try. Meantime, I have a couple of questions.

1) cabling for digital modes. Looking to run PSK-31 & WSJT-X. Am experienced with those modes on Icom 756 Pro II, Flex 1500, and K3. All I need is the cables. From looking at the schematics it looks like all  I need is a couple of 1/8" stereo Male-to-Male cables. No real question about the receive side. Looks like the transmit side (KX2 mic input) is a 4-conductor jack with separate signal & logic grounds. Will it work with a 3-conductor cable which would seem to short the grounds together?

BTW, I discovered that Apple iPod earbuds (4-conductor plug) don't work. I tried pushing the plug all the way in, and pulling it out part way. No joy. My expensive Bose earphone work well, as do my inexpensive over-the-ear "cans". Looking for a set of earbuds with 3-conductor plug to keep the package small.

2) can anybody recommend a small (cheap) headset? Maybe a computer, telephone, or gaming headset?  I'll probably spring for the MH3, but would like a hands-free option.

KX2 is going along  to a family reunion this weekend. We are both looking forward to it.

73,

Jim, WK8G

My Apple earbuds with 4-conductor do work on my
KX2, Jim.

Phil,

Correction: earbuds in- question are from iPhone 5 and have 4-conductor plug. They do work with the iPhone but not with KX2.

What correction, Jim?  Mine are from an iPhone 5s
and work fine with KX2, KX3, various MP3 players,
etc. They look like this:

Caveat: I use only the right side because my left
ear doesn't work

Jim,

Re: Data modes ---
Yes, all you need is the cables.  As far as connecting the logic and RF
grounds together, you may find some improvement by turning MIC BTN in
the menu to OFF.
Many have been doing that with the KX3, and the KX2 should behave similarly.

If you want the 'best of both worlds', then you will build special
cables that use a 4 conductor jack to separate the grounds.
