Mark,
When you have the problem, look at the voltage at P1 pin 6 (that is
VRFDET signal)?
If that is high, the MCU will limit power drastically.
Make sure Q1 is properly oriented. If that does not help, try a mod to
the KSB2 - reduce R9 to 1.5k and cut the trace between P1 pin 6 and the
Mark,
Pin 5 of U2 provides ALC threshold voltage to the emitter of Q1 on the KSB2
board. The 5.89 V you measured on Pin 5 suggests that the DAC input
register B didn't properly load the data word from the MCU. I would check
the solder joints on all U2 pins and Pins 14, 16 and 17 of the MCU
Today I finished the KSB2 adapter and installed it into my K2. It worked

Fred, take care not to put too much solder on the pins of the crystals when
you install them in your new KSB2. One of the most common reasons for low
gain is a bit of solder that puddled around the pin under the crystal can
where you can't see it and shorting the signal path to the can. Remember,
I just completed a number of mods for the SSB module, described by KI6W
