Don,
I just upgraded my firmware from 2.01 to 2.04 (along with the accompanying
io upgrade) on my K2 sn 1309.
I didn't do a good job of saving my settings, so I'm out of cal.
I've gone through all possible (I think) kinds of calibration methods.
What is the correct method? My main concern is SSB.
W3MC - Mike - MD - K2 - 5568Thank you for your QSP
assistance!
Thanks Mike in MD for the QSP As always here in
Florida
Kevin has QSB. In and out of the noise. I know it does
not help only running 10 watts But hopefully that will
change as winter progresses. If that ever happens

Hi Folks:
Both 20M and 40M were 'difficult' at best last night... at lease from
the midwest.
However, I must say that Mark, W7/G3XYS, with his KX1, had by far THE
BEST signal into mid-Missouri on 20M last night.
Of course, I realize it's just propagation, but I did want mention

I know the CAL PLL process requires a CAL FIL after it
to make everything work correctly. My question is if
I want to re-do the CAL FIL, do I need to do a CAL PLL
first? I can't tell for sure from the manual, but it
seems to me that I wouldn't need to. I'm thinking I
should probably at least
Ben,
You can just do the CAL FIL alone.
In fact, you can do CAL PLL alone too.
Only one 'caution' - if you are to retain good dial calibration, be certain
the 4 MHz reference oscillator is set properly before doing either CAL FIL
or CAL PLL. The best method of setting the reference is using

At least my Racal RA6790/GM labels the front panel control IF Gain.
As a side note, I find the RA6790/GM to have the best ergometrics of any

I couldn't find this in the manual. On my K2 (05767), the frequency in the
alternate VFO is not maintained when you toggle the two VFO's. For instance,
if you are tuning on VFO A on 20M and then go to VFO B and switch to 40M, the
VFO A also switches to 40m in the same mode that you were using
any pics of the case ?

Seems to me this wouldn't be too hard. Would need to
switch the 4 control lines that pass between the 2
K2's and the KPA100/KAT100 combo via the I/O cable,
and then switch the RF path between the 2 K2's and the
KPA100/KAT100 combo. You would have to be very
careful about the switch for the RF

Hi,
I have already built such switching box using fast relay and an external key
from the K2 (and for my test, another rig and etx. key) This is working. And I
think by using 2 K2, we will be able to give more intelligence to the swtiching
box. but my main concern is between the 2 IO lines
If you have the KDSP2 installed, can you still use the N6KR method to set
the reference? I would think you would want it in Bypass.

On my side, when doing CAL FIL, I always BYPASS the KDSP2.

If you
Dohn,
There is no relationship between setting the 4 MHz reference (using any
method) and the KDSP2.
The problem with the KDSP2 (and the KAF2 to a lesser extent) is that it
contains a low pass audio filter which will mask seeing the upper frequency
end of the actual audio passband when aligning
Jean-Francois,
I am trying to think of some reason that this scheme will not work well.
The thing that occurs to me first is that there may be some initial
'strangeness' with the power level controls just after switching K2s, but
that should straighten itself out after a few dits - but there is
second, if the RF gain control is turned or touched at all, the rig
immediately goes silent and all the bars in the bar-graph meter are
illuminated. Over a period of about three seconds the bars are
extinguished, from right to left, and the sound comes back up. The
control
itself works in
Another, probably less messy, approach is a few drops of DeOxit into the pot
either along the shaft (that's the usual ingress) or, if there's any gaps
around the electrical contacts or case in back, in there. DeOxit comes in a
small squeeze bottle with a very fine metal tube applicator.

Bernie,
Do you have the KDSP2 installed? If so, there is a gain stage in the KDSP2
that can give your audio a boost. Check the KDSP2 manual.
