I have a question related to the audio signal of the
K2.
I have completed the base K2 and during stage 2 I was
already concerned about the low audio output.
I first thought that my headphone was to blame, a 16
ohm unit that is not able to transfer all the audio
power from the amplifier but now

Bruce,
What is the starting frequency, and what is the frequency just before the
'End' message?
If the frequency stays at the high end (near 12100 kHz), and does not go
down in frequency, you will have to look at the PLL Reference oscillator and
its control signal which begins at U5 pin 7.

Hello
I am trying to do the VCO linearization for the K2 #5713. It start but
the frequency never goes down nor does the "d" show up saying it is
setting points. But after 8 Minutes it does say END. Nothing else. I
do hear signals on 40 but they are nowhere near the same frequency as
the K
Hello Fellow Elecrafters,
After two years with my K2 I bought a KPA100 upgrade but have had second
thoughts about needing higher power so on the block it goes. Included with the
sale is 1) KPA100 (not built) bought in February 2006, 2) K2 MCU and IOC
firmware upgrade 2.04, and 3) 10mBPF/VFO/AL
Gerald,
That certainly sounds like it might be hard to isolate.
I may be wrong, but from the behavior it sounds like you have a relay with
points that are not making good contact - when you put a bit of RF through
it, it becomes OK for a while. Please be aware that this is just
speculation on my

Floyd,
I don't know about any particular 'issues' with the K2 that have not been
addressed - the answer will depend on your definition of 'issues'.
There are practical limitations with any given design, and the K2 is
included in that list. The specifications point out these limits.

First and foremost, Ill take this opportunity to thank everyone who

One of the characteristics I look for is response time / refresh time /
time to read. It is much easier to make adjustments that depend on
measured voltage or resistance if the meter quicks refreshes the
readings. Some multimeters, especially some of the Flukes, are
excellent in this regard.
A couple of years back when I had my K2, there were some issues with it
that were unresolved at that time. I'd like to know if those items have
been resolved over the past two years and if so I might consider
building another K2. Rather than posting the info here, I'd prefer to
email the info

Heya Jack ..I took the "easiest" path and just connected on the PC
side of the KRC2 .. 2,3,5 to the PC, 6,8,9 to the XV and added
necessary jumpers (all but ALC). Only thing I'm worried about is the
total cable length on AUXBUS, from K2->KRC2->XV is about 4 feet ...
I'll know later today when it

After trying lead-based and lead-free solder on some of the mini-kits, I
went leaded for my K2 in the end. I knew it was going to be a whole lot
easier especially if I ever had to rework anything... but this comment
from Eric really stunned me:
