The use of a broadband noise source and an audio spectrum analyzer

easy and uncomplicated.

Hi all,
I decided to recalibrate the filters in my K2 because I noticed a small
RX-TX frequency difference which made it hard to use my NUE-PSK.
But I didn't get the calibration working...
I enter filter calibration menu. I select FL1 in open-mode. I adjust (in
RX) the BFO and watch the audio
would think that is a
required condition.

Hi group!
I want to sell my K1-2, 80 + 20 m.
It's proffessionally built, I have worked many years with electronics
mounting for the industry. I have also got an degree from a solder-course.
I built the kit in spring 2005, and after that I have
Hi all,
This is way OT, please forgive me.
I have a simple question. Can any of you living in USA help me to
register an Gmail account on Google?
To register you have to have an cellphone in USA. I think they will send
a password as a text message.
If you want to help, please contact me
Tnx a lot guys!
I have got two invitations from gmail from two of you.
I did not know they had that invitation-thing, really smart people at
Google!

Hi,
My K2 #4904 is now on air!
SSB and RS232 option is still in their bags, but the basic K2 is up and
running! (Yes, I'm pretty proud of myself ;-)
I tried to use my external manual tuner with it.
But that was really difficult!
As soon as I rotated a tuning-knob the K2 adjusted it's power.
My K2 survived the smoke test.
It's not aligned yet, but I can hear and transmit on all bands.
Stupid DMM, I lost some good building hours there!

Hi again,
This is not an question about my rig, it's more like a wondering...
I have made two automatic calibrations on my K2. The first one early in
the building-process and the second was the VCO linerization.
Are these processes run once and not possible to run again?
Or is there a way to
Hi gang,
My reading for Q7 base is too low, but not shorted.
I get 760 ohm...
But I should get 2.5 to 3 k ohm.
I have worked my way through the schematics.
At R62 I get zero one one side and 870 on the other.
At R60 I get 870 and 760.
The low resistance must be somwhere between R60 and Q7 base.
it at auto I get 760 ohm...
It must be different values of voltage the DMM uses to measure in auto
and manual.
OK, case closed.
I will proceed with alignement in step III
Sorry for the noice on the list

A combination of guessing and logical thinking.
In auto I get wrong reading.
In manual 10 k I get 2.7 k.
In manual 1 M I get 3 k
So it's 2 against 1...
And the two values is what to expect, the odd value is - odd...

Hi all,
A bit off topic, apologize for that.
I want to have the best performance per cost antenna for my K1 and K2.

antenna. (I dont't drive and work QSO's at the same time)
* It must cover 80 - 10 m, but it's not necessary to

Look at Appendix F in the manual.

I have completed step 1 and all functions checked out 100%.
I have completed the 3 paragraphs of resistors and now moving onto the

Hi, I'm building K2 #4904 as a follow-up to my K1.
My manual says (at page 29) Some holes in the front panel was masked...
I have no mask-tape over the holes, and there has never been any tape
over the holes. It's painted grey on both sides.
What is the purpose of masking?

I'm going to order a K2 in the nearest days.
I'm alreday built a K1, #1978. (If you start to build, it's hard to

To the question:
I see many articles on the Net about different modifications to the K2 rig.
How is this reflecting the real wold?
