Hello everyone. I installed a 60 meter board last night and it seems to have a

on the audio. I turned on another radio and had WWV loud and clear at 5000 kHz
in that radio. When I increase the frequency the
Hey folks,
I did not operate during the big contest this weekend but spent a bit of
time listening. I just got my KAF2 audio filter built and installed and
was anxious to see how it did. While tuning around I noticed some
problems that are probably just characteristics of the rig.
On 40 CW,
Harvey,
Re-check the VCO range (voltage on the left end of R30), and be certain all
the ands fall within the proper range. It is normal for the VCO voltage to
become so small below 5300 kHz that the tuning will not continue on down to
5000 Hz. Also the response of the bandpass filter may fall

I am doing the 4 MHz oscillator check and I can't seem to get a reading on the

checking the calibration without using the probe that was supplied

This is cool. Hopefully some one will do a engineering comparison report of
the IC-7800 vs the FT-9000D at 3-5 watts.

While I own an IC-7800, I use my K2 for QRP contests, and my K1 and KX1
for more portable operations (though the K2 sometimes does duty there too).
I have never missed my IC-7800 when using my K2; I have sometimes missed
my K2 when using one of the K rigs, mostly a band issue.

I believe it is the TX side. Here's why:
The SoftRock series of SDR kits are fun for looking at this. The
receiver is extremely wide, on the order of 50KHz to 100KHz, depending
on your version and sound card quality, so there really isn't anything
analogous to the filtering artifacts you
There are several buttons on my K2 that are rarely

I agree. I've never understood what problem

unnecessary in a rig with split and I detest

Thanks Don. I think the VCO voltage is too low at 5000kHz. At 5300 kHz it
reads 1.084 vdc on my Fluke 179. I will have to go back to the adjustment
routine in the K2 manual and see if I can shift all the voltages enough. On
my previous K2 it worked great at 5000kHz. The buzz saw sound to me is

I found that I could adjust the VCO voltage to keep the VCO in lock at
5MHz -- however, I have yet to copy WWV at 5MHz. And, I did get that
'buzz saw' sound when the VCO is not in lock. Good luck -- if you
find you can copy WWV at 5M, please let me know about it.

It is likely not a firmware issue, but a problem with calibration - the
adjustment of the trimmer cap is critical. I can give you a 'non-Elecraft

If you want to be assurred of a proper trimmer cap setting, make up a 100

Hello,
This Saturday, June 3rd, is the 9th Annual QRP TAC Sprint. We are turning
back the clocks to the CW Only Sprint due to the lack of any SSB or PSK31
contacts last year.
So the contest will be CW only. Look for WB3AAL out on the Appalachian
Trail. If you find me and work me from the AT
Just built mine (after it sat around for about two years). My first attempt
at SMD, a great first project - really a lot of fun. I Still haven't
installed it yet, though.

All those that won divisions in the 2005 TAC Sprint, sorry but I am late

Thanks Mark. My other K2, S/N 5022 receives WWV on 5000 kHz real good. This
one is S/N 5404. Last night I tuned my Sony 2010 receiver to 5000 kHz and it
almost pegged the meter...the path just happened to be open. I'll let you
know if I am able to get this rig to do it.

Don, I adjusted the VCO range and ended up with 0.551 vdc at 5000 kHz on the
meter and I can now receive WWV at 5000 kHz. Apparently thats enough voltage
to work. What I did was adjust L30 so the voltage at 4000 kHz went from 6.52
vdc to 7.35 vdc. All voltages are between 2.715 vdc and 7.350
