Hi all,

I fiddled about finding a somewhat better qrg.
the result is:
now dj8wx is transmitting on 8970,0177Hz.

best regards
Uwe/dj8wx

Hi Stefan, hi Henny,

Stefan, part of your question has been answered by Paul Nichelson.
pse see:

http= ://tech.groups.yahoo.com/group/VLF_Group/message/17456

the reference is a= GPS diciplined 10MHz signal.

no divider in use.= the accurate sine wave is generated by the high speed microcontroller AT90S2313followed by a R matrixc and a  lowpass filter cutqrg 10kHz.

the phase is GPS sy= chronized. the time is locked to GPS 1pps.

negative: the resol= ution (step size) is 0,3mHz (32-bit). theoretically. really: 63xmHz. the eeprom doesnt take any notice of the last two signs of the HEX group. so it can generate near 8970,000Hz:  8970,022xHz or 8969,959xHz.

best regards=

Uwe/dj8wx

Hello Henny, Uwe, VLF,

Ah, you've already seen it ;-)
I just wanted to post that i have splitted my 60000 window. Now the range arround 8970.000 +- 4 uHz and 8970.020...8970.025 is visible.
Since it has stored the last 10 days or so in the buffer, DJ8WX's transmission of last week is now visible in 47 uHz= as well.

Uwe, what is the exact frequency on which you are transmitting? What is the original reference frequency and what is the divider ratio?

May there be a conflict with Hennys transmission? Now we are in a range where it is important to know the frequency to a uHz! If i look at Victor's spectrogram, it looks Henny is slightly below 8970.022 Hz, maybe= 0.2 mHz. But this may be not enough to make out the difference (?) Oh, i just looked at the spectrogram and see a faint trace at 8970.0217 Hz. Is it you= , Henny? It's still to much guesswork but a first step on the way to a prope= r ID. 3 dB QRO would be a good way to check that :-)
