PLEASE MAKE THE FOLLO WING CHANGES TO THE MANUAL BEF ORE

PROCEDING TO EN SURE THAT THE K60X V FUNC TIONS CORRECTLY

Page 13: Delete the third assembly step from the bottom, which begins “Switch to 40 meters….”

Page 16: At the end of the first paragraph, add the sentence: “Leave D 1 9 set for PA 6 0 = 4 0 , even when

using KPA100 kit revision C.” (See detailed information below.)

IMPORTANT OPERATING NOTES:

1. Using the KPA100 on 60 meters: Recent KPA100 kit modifications (revision C) allow high-power

operation on 60 meters. However, these changes do not include a revised 80-meter low-pass filter. For 60

meters, you’ll still use the KPA100’s 30/40-meter low-pass filter. For this reason, you must leave the

K2’s D 1 9 menu parameter set for PA 6 0 = 4 0 (see K60XV manual).

2. Using TUNE mode with the K60XV and KAT2 installed: If the KAT2 is in either of its autotune

modes (A U T O or A LT ), and you’re on a transverter band configured for LP mode (Low Power, 0 dBm),

holding TUNE drops power to 0.2 milliwatts maximum. You can override this behavior by holding

D I S P L A Y along with TUNE, or by selecting any KAT2 mode other than A U T O or A L T in the menu.

3. KAT2 modification for use with K60XV LP mode: In some cases the LM358 op-amp on the KAT2

can load down the K60XV's low-power RF detector (at the emitter of Q2), preventing the K60XV from

developing a full 0 dBm (1 milliwatt) signal at the transverter OUT jack. To correct this, change R6 on

the KAT2 from 47 ohms to 470 ohms. This resistor is supplied with the K60XV kit. R6 is on the bottom

of the KAT2 control board, and can be changed without removing the KAT2 module.
