K60XV Upgrade Order Page
: Revision 2.04P
or later main microcontroller firmware is
required (U6, Control board), and revision
1.09 or later I/O Controller firmware
(U1, RF board). Serial number 4060
and higher K2s already have these revisions. To check the revision, hold any
switch while turning the
KAT2 and KAT100 ATUs:
For 60-meter use, the KAT2 requires revision 1.07 or later (order #FWKAT2).
The KAT100 requires revision 1.05 or later (#FWKAT100).
To determine your KAT2 or KAT100 firmware revision, use the
KSB2 SSB Adapter: Revision 1.07 or later (#FWSSB) is required if you plan to use SSB modes with low-power transverter I/O. To determine the revision, set the SSBA menu entry to BAL, exit the menu; then hold VOX . (Be sure to return SSBA to its original value after checking the firmware revision.)
K2 Rear Panel: Starting
with K2 serial number 4088, two holes
for phono (RCA) jacks were added to the
KPA100 (K2/100's 100-watt
stage): The KPA100 cannot be used on 60 m unless it includes (1) the circuit
updates made recently to improve high-SWR handling; (2) the newer version of the
KPA100 shield , which includes grounding clips. If your KPA100 manual is
revision C or later, both sets of changes are already in place. (Another way to
tell if your unit has the circuit changes is to look at toroid L18 on the
KPA100; it was recently replaced by a jumper.) The SWR-related update kit is
order #KPA100MODKT. The shield
upgrade is order #KPA100SHLDKT. Once
these changes are in place, you can use the KPA100 on 60 meters, and can
optionally upgrade to KPA100 firmware revision 1.09. This revision allows up to
a 2:1 SWR before reducing power. (Use the
