Hi all,
I've got a K2/100 with a KSB2 that I've just installed and am trying
out. My mic has an HC-5. I am aware that this element does not have low
output for the K2. I've done the R14 mod, replacing it with a 10K
resistor. It's working better than it was, but I still don't seem to be
getting muc
Bob;
I have a mod that will reduce the K2 phase noise. The implementation of the
mod is not easy. Some of the changes require the ability to measure phase
noise, and most folks don't have this capability. The mod can also degrade
the PLL stability. Therefore, I do not plan on publishing the mo

annoying. This phenomenon only occurs on 60 meters. Has anyone else experienced

Yes, this is normal. The KDSP2 pretend
David,
To repeat the old adage - check soldering, then re-check soldering, and when
that is done, check the soldering.
In particular, look for too much solder causing solder bridges.

power off and check the resistan
If your MCU FW is older than 2.02A, the KPA100 comes with free MCU and IOC

But wait, there's more!
If your KSB2 FW is older than 1.06, you also get a free KSB2 FW upgrade
(refer page 22 in the KPA100 rev c manual). This is required because the ALC

Steve,
Elecraft normally supplies any needed firmware upgrades with the purchase of
a new option. It would be wise when talking with Lisa (sales) to point out
that you believe you need firmware upgrades.
Elecraft does try to keep track of which K2s are at which level, but with

Kent,
Count the holes - if there are 10 holes, then it is the newer shield. There
is only a difference in the size at one corner - the corner that covers the
RF output jack.
The 'placement' of the original 7 holes is unchanged - 3 holes were added to
the newer shield to accomodate the groun
Hi all,
Does the KPA100 kit include new ROM chips for the K2 or do you also need to
buy the FWK2MCIO upgrade? My MCU is 1.04d and the IOC is 1.02. I seem to
remember reading in the online manual, well.I thought it implied that
the chips were included in the KPA100 kit.
72 and a half,
Steve,
I've received two very helpful hints to help me determine which is the old
KPA100 shield and which came with the Shield Upgrade Kit:
"The new shield should have holes in it to accept the three added
grounding clips."
and

Hello All
I am posting this again.
I have a problem with "HI CUR" On the K160RX
It comes on for a second and then shows .5 watts
regardless of the power setting.

Hearty thanks to Jim; K4ZM. He said I sounded "tinny" and to read back my
BFO settings. The freq was reasonable but the bandwidth was 2,200 hz. That
ain't right!
Using OP1 really helps! I paid good money for the SSB filter, might as well
use it for transmitting. I have NO IDEA how it got from OP1
Good Afternoon,
My stint as a teacher of emergency communications has come to its
holiday hiatus. No classes for a few months. It is nice to have Saturday
morning back but I do miss teaching. My students always kept me on my
toes and rewarded me by learning. I don't think you truly know
that did it, thanks

Er, ah, I wasn't aware the K2 made any objectionable noise. What's your
specific issue?

Roy;
Try adding several feet of coax between the tuner and the antenna and
try again. It appears you may have a voltage maximum occurring at the
tuner - adding the coax will move it out a ways. There are just some
impedances and feedline lengths that tuners have a difficult time
handling.
Roy,
Getting a really good RF ground for a 2nd story shack may require more than
a 1/2 inch copper pipe, it may be a good ground at DC, but actually may have
a high impedance at RF (depends on the frequency).
The easiest thing to try is a quarter wave counterpoise wire (open at the
far end a

I thought that installing MCU1.05 there would be ample RF sampling rates
taken to avoid erratic LED displays. The updated firmware seems not to be the
solution.
With a 50 ohm dummy load on the KAT100 output only the leftmost LED lights
up and K2 SWR is 1:1 regardless of power or band in use.

Look for me to activate a covered bridge or two today 11/20/04.

I would look in the area of the Low Pass Filter section or the Bandpass

connecting the antenna to the rf out jack and then moving it to W1. If the

yes, K2 #4520 is up und running :-)
After i have changed the two transistors Q9 & Q10 the internal frequency

It is really a pleasure to work with the K2.
