Hi Lance, The resistor and jumper blocks included with the headset are only for the K2.
The K3 requires no mods to use the Proset-K2 (or the MH2.) Just turn on the miic bias in the K3 menu and you are good to go. 73, Eric WA6HHQ _..._ -----Original Message----- From: LANCE COLLISTER <[EMAIL PROTECTED]> Date: Sunday, Aug 31, 2008 7:32 am Subject: [Elecraft] Microphone connections for K3 #1540 To: <elecraft@mailman.qth.net> Hello K3 gurus! I received my factory built K3 this past week, and yesterday received my K2 Heil Pro-set and some Anderson Powerpole connectors... Last night I wired up a serial line splitter so I could connect my K3's serial port to the same serial cable that goes to my sequencer (that will switch any of my XMTRS into XMIT)and CIV level converter (for my IC746). So it looks like I am getting close to being able to make some noise with it ;-) Currently, I run my Heil #5 boom mic (along with the LINE OUTPUT from my computer) through a W2IHY Audio Equalizer and Noise Gate (and then through interrupt relays) before they go to the Mic input of the IC746. With the K2 Pro-set from Elecraft, I received a resistor and a bunch of jumper connectors with an instruction sheet on modifications I need to make to the K3 so it will be able to work with the K2 Pro-set. My question is this: If I use the current microphone/audio in arrangement, do I still have to modify the K3 for the K2? If I install all the jumpers and resistor into the K3, will I be prevented from using the W2IHY Audio Equalizer and Noise Gate in front of the K3? Will I harm anything by just trying different setups the way the K3 came from the factory? MNI TNX for any guidance or suggestions you may be able to provide.
