Hi everyone,
I'm trying to do the resistance checks at the end of the control board part.
A lot of the values seem right, but I'm not sure about some of them. Due
to inexperience in kit building and using a DMM, I may just be reading
things wrong (I have built a couple of small kits).
For
I've come to the Alignment and Test, Part II. I think I'm having a problem
under the BFO test.
Following the instructions, I switch to 40m, hook up the frequency counter
to TP2, and get a reading of 4913.52. The manual says I should get
something between 4908 and 4918. So far, so good.
Thanks for the info.
To clarify some things:
My indoor random wire antenna is _very_ makeshift. My rigs hook up to an
LDG Z-11 tuner with coax, then on the tuner's output it goes to coax again,
which goes to a 4:1 balun. One end of the balun goes to the antenna, the
other to some
Ok, here's an update.
I raised the HI CUR limit to 3.0 Amps, and haven't seen a HI CUR warning
(except sometimes when power is set to 15 Watts). I went through the Part
III Transmitter alignment, and was able to peak all of the L's and C's
without getting any HI CUR messages.
As a side
Sorry to interrupt anybody's field day plans!
I just built the KIO2, but couldn't establish a connection with
Hyperterminal and K2Remote software.
So, I went to the DC Voltage chart, and found the following differences (I
used a 13.8 V power supply). (The values with *'s by them in the
I don't think it's a problem with the jack screws, as they back out
completely into the housing, and I can plug in the cable all the way to my
computer and KIO2 board.
My biggest concern is that P4-7 on the control board is putting out 0 V.
From the troubleshooting section of the KIO2
Ok, I checked out the voltages on the control board to see if that might
shed some light on anything. (See page 15, Appendix E, Troubleshooting in
K2 manual)
Q12-E: 4V (not 6)
Q12-B: 4.5V (not 7)
U2-1, 2, 3: 4.07V (not 6.9)
U2-5, 6, 7: 4.5V (not 7.3)
U6-24: 0V (not 5)
U6-25: 5V (not 0)
Thanks for the time looking at this everyone. I was just worried about P4-7
because the manual says there should be 4.5 V there. I do not have KSB2,
tho.
Yes, the port menu item is on.
I'll look at the KIO2 and AUX boards a little more closely. My computer
hasn't got any serial ports, so
I have the port settings set up exactly as you said. I thought about taking
it to work next week where my computer has a real serial port, I'll report
back then on how it goes.

Jason,
Do you have the computer port set correctly? 4800 baud, 8 data bits, no
parity,
Here's another thing I just noticed.
When I hit the display button, my current now says 0.00. Obviously this is
false, and the K2 seems to be working fine otherwise. I'm worried, tho, if
I need to do some alignment or calibration to peak the current, that I won't
be able to do it.
The
I'd like to use my basic K2 with this amp (5W in, 50W out) in CW.
It has an RF keying circuit, so that means all I have to do is hook up the
K2 antenna out to the amp, and the amp to the antenna, right? Can I ignore
the ALC socket and other connections?
Also, as to QSK on the K2, should I
Try changing your CRT monitor's refresh rate first.

Those resistance values should be fine. I asked a similar question when I
was building my K2, and got that answer.
Question: I'm measuring resistances on Control Board,
ala page 21 table. On a few measurements, I'm getting
MUCH higher resistances than table indicates:
