I have just acquired a very early (SN 100) K2 with the following options..
- KNB2 Noise Blanker
- KBT2 Internal Battery (with dead battery)
- KSB2 SSB Adapter
- KAT2 Antenna Tuner
Basically the radio seams to be working but with a few anomalies like..
- AF Gain noise (sounds very much like what is described in the
"Alternative Wiring.." modification writeup)
- CW all seems fine with about 12 watts out and "POWER" control works as
described.
- On SSB the POWER control does not seem to vary the output power.
- On 80 and 40 meters when transmitting SSB at most any power level
sometimes I get the HI CUR warning.
- The frequency seems to be about 50 Hz off.
- ATU seems to work fine.
The radio came with a Kenwood Dynamic Hand Mic (800 ohm). It also seems
to work but I have no way of knowing if it is the best fit for the K2.
As far as I can tell, no updates have been done to the radio. The
firmware shows as 1.04C and IOC of 1.02.
Rather than start troubleshooting each little issue I would like to put
together a plan to bring everything up to spec and then upgrade from Rev
A to B. In the immediate future I want to add one more module, namely
the K160RX and of course will need the right upgrade kit(s).
I have had enough kit assembly experience in the past that I THINK I can
do the work, but I need help with a plan that puts all the steps in the
right sequence, given the early version I have and the possible fixes
that may be needed along the way. I have the Revision B upgrade
documentation but I need some hand holding as to what pieces I will need
and in what order. I really want to do this right and not mess up this
nice radio. At some point I may just decide I need to go the
Builder-for-Hire route. You get the idea!
Any help would be appreciated.
Thanks,
Dan
