LF: Wildwood Loran-C on air again

[Markus Vester <markusvester@aol.com>]

Wildwood is again transmitting experimental Loran signals on GRI 8970 M and X tonight. Traces are becoming visible here in the two rightmost slots on

http://www.alice-dsl.net/df6nm/LoranView/LoranGrabber.htm

 

On the US east coast, it should be audible on 100 kHz, and some of the familiar lines should have reappeard on 137 kHz spectrograms.

Best regards,

Markus (DF6NM)

There's also a 8970 master emission, with the same fading history, and about 2.4 ms earlier here than if it would come from Dana. Thus Wildwood is currently transmitting both M and X signals.

Hey Chris,

 

it's there! I have added five slots 8970 m,w,x,y,z to the right of my LV display, and since 22 UT I'm indeed getting a trace in the X slot allocated to Seneca. It's about 12 pixels (0.55 ms) late here, so either the emission delay or the location must be wrong.

 

Someone reported that the emissions are actually from the Loran Support Center, Wildwood NJ (Cape May, 38.9464N 74.8668W).  According to Google Earth this is 6595 km from me, 164 km further than Seneca. That's exactly 0.55 ms extra delay! So we know that they are transmitting from Wildwood using Seneca parameters. 

 

If you like to see it yourself, you can simply add a line containing "8970x" at the end of the stations section, after the GPS entry.

Thanks for the tip!

 

Best 73,

Markus

Hi Markus,

>From the 'time-nuts' list, yesterday evening around 20UTC the 8970x Seneca N.Y. station was reported as being active.
