Steve,
When you can receive WWV and WWVH at the same time, that is handy
because there is a tone both at 500 Hz and 600 Hz on each minute. WWV
and WWVH do not transmit the same tones at the same time.
Glad to hear that you are now up and running and are about as close as
you can expect.
Yes
Don,
I finally got to within 10 to 15 Hz at 10 MHz now. I decided to use MixW
for the 500/600 Hz WWV tones. It works really well for that part of the
calibration.
I had misread your web site. You do endorse the N6KR method. I did find
the WWV Signal Format web page. Out here on the west coas
Steve,
Yes, the "4 MHz" reference may have to be set a few Hz different than
exactly 4.0 MHz to calibrate the dial accurately.
The best method I know of is to feed the K2 audio into a computer
running Spectrogram. This method compensates out any difference between
4 MHz and the actual r
Don,
Sorry I didn't fully read your comments before my first reply.
Could you briefly explain how you calibrate with the 500 & 600 Hz
markers? Can it be done in real time while tweaking C22? I can't do it.
I have C22 set exactly to 4 MHz via the 20 MHz WWV method, with a
perfect zero beat. Ye
Don,
I got back it in the ball park. I read the W5YR instructions on your web
site, about the 5th harmonic of 4 MHz of 20 MHz. Fortunately WWV on 20
MHz is still coming in on the west coast, but fading out. After all this
work, I am back where I was except about 40 Hz low for zero beat on 10
Steve,
Your steps are correct.
It sounds like you are off by the amount of your sidetone pitch.
Were you receiving WWV in LSB or USB mode? If you used CW mode, that
would explain the difference.
Are you quite certain that you tuned WWV accurately? Do not 'set the
dial at 10,000.00', but i
I was trying to calibrate my K2/100 and had it within 10 Hz according to
WWV 10 MHz. I should have left it alone. Now it is off by about 700 to
800 Hz on 40 meters. Ouch!
Here are the steps I did so far:
1. I set the C22 trimmer on the Control Board by the N6KR method at
