"Does anyone remember a mod where a 5.6K resistor replaces the 1K
resistor at R14 on the KSB2 board for increased mike gain? I cannot find
my notes on this mod. I thought it was a KI6WX mod, but I can't find it
in John Grebenkemper's write-ups."

Although this is a popular mod for those using low-output dynamic mikes,
I don't believe it was ever included in the "official" mod list on the
Elecraft Web site.
I replaced R14 with a 6.8K resistor on my KSB2 to get adequate mike gain.
Before that, I had to holler into the mike to get the VOX to trip.
