[Elecraft] (K3) Headst/Mic

[Tom Boucher]

An alternative K3 headset in place of the Yamaha CM500, which appears to be unobtainable in Europe, is the Koss SB45. I just bought one of these from an internet supplier for 20 pounds (about $30) and it seems quite comfortable and it does have an electret mic element, not a dynamic one. The 3.5mm jacks plug directly into the rear panel Phones and Mic sockets. MAIN MENU: MIC SEL is set for RPL with bias ON.

I have the MAIN MENU: TX EQ set for a rising characteristic (0,0,0,+3,+6,+9,+12,+15dB) and it sounds just great in the monitor. However on-air tests may show that a bass cut with flat characteristic (-16,-16,-6,0dB the rest) per K9YC recommendation may be better.
