[NCC] [MRRC] Headphone questions

[Jim Breakall]

Hello All,

I added the ModMic to a really light pair of Sennheiser headphones that 
are almost like you do not know anything is on your head.

The Mod Mic works great with a K3 so far plugged into the rear connector 
and people say it sounds good.  The neat thing is that
it attaches with a clever little magnet clip and can easily be removed 
when you just want to use headphones like for CW.  It needs
to have bias and that is button 2 in the K3 to turn on.

Of course people tell me that anything works with my voice and I always 
get more power out with my voice on the wattmeter
than other people.....haha.

Good luck.

They also worked in the car this past weekend with no problems - something the old Heil Proset did not like, with all the RF floating around (loud clunks listening to my own signal).

I kluged together a mount which sort of held it in place, but I found I had to push it the last inch to get it close enough to my lips for full modulation.

The issue I had over the OHQP weekend was wires breaking in the cable where it attaches to the headphones, right in the connector that is referred to as a 6 pin mini XLR.  (I probably tugged on it too many times.) Fixed the right ear (red wire)  Friday night.  But never checked the microphone portion again until the OHQP had already started.  Started on CW but later when went to phone had no mic function.  The white wire was broken, so found an old pair of headphones only and operated CW with those while fixing the Pro 7 mic wire.  (Never did put the shell back on the cable end, in the interest of time just taped it to microphone boom as a "strain relief".)
