I just found this conversation regarding the suitability of using CAT5/6 for K3 microphone cabling:
http://elecraft.365791.n2.nabble.com/K3-Microphone-Cable-td6333100.html W4TV says: "It will work fine. Just be sure to use one pair for mic and mic return (pin1 and pin 7) and one pair for PTT and ground (pin 2 and pin 8). The other pins can be any wires but using twisted pairs for mic/mic return and PTT/Ground will provide the best balancing to reduce any hum/RFI issues with the unshielded cable." Should I use one twisted pair for the hot and return? And thank you for the tips on tx equalization. ---------- Forwarded message ---------- From: david Moes <[email protected]> Date: Fri, Mar 1, 2013 at 7:04 PM Subject: Re: [Elecraft] XLR microphone wiring, K3 rear panel To: [email protected] Wire it as Hot to tip and return and ground to the sleave. I use the same mic. I find it a little boomy so I cut 50hz to minimum 100hz to minimum 200 HZ to -6 400 to -3, 800 at 0 and the rest to +4 except the 3200 hz at -2 Bias off, and High gain [email protected] VE3DVY On 3/1/2013 5:16 PM, Benson Wills wrote: > I'm hoping to get my mic wired for the contest tomorrow.
