Re: LF: DJ8WX 8.97 kHz

["PA1SDB, Peter" <pa1sdb@amsat.org>]



Laurence, Uwe, Markus, VLF.

 

I think it is a good idea to install a hot line between Laurence and Uwe !

In case that noise drops again, Uwe is called to produce a finger print... :-)

 

Perhaps Lurence can take a look with the cursor to discover at what time that the signal level did rise suddenly at 05z (???)

Was there somthing special happening at one of both sites at that moment ?

Like sunrise, rain, snow, dewpoint, Ect....

Hi Laurence,

http://kl7uk.com/slow00000.jpg

 

exciting indeed - is that really Uwe's carrier? Seems too good to be true... As it's exactly 8970 there could be an artifact from some stable source, eg. from an injected GPS 1pps (?). Let's hope the noise drops down again when Uwe does his next frequency step.

Hi Markus,

OK., I should have the site refreshed.

<Is there any particular reason why you prefer Castle mode from straight DFCW?

dreamers preference I guess.

since 2110UTC the TX will be on the air in carrier only mode.  8970.000Hz (I hope).

Uwe, 

 

the VLF grabber seems to be uploading ok every half hour, as it should.

 

Good luck towards Alaska! Is there any particular reason why you prefer Castle mode from straight DFCW?

PS. Ill stay on the air in CASTLE mode 16666.7sec/dot 1mHz shift or simple carrier for a week or so until Laurence KL1X gets the signs on the screen.
this done Ill try other modes.

Hi Uwe,

 

your 8970 Hz signal is widely visible across Europe
