Someone build me a transmitter

[Black Cloud]

Hi,
yes, the signal from Mainflingen is strong in all Europe... maybe less just at extremes latitudes ...like northern and southern places... don't know. The central europe is totally well covered by DCF77 , and so clocks and other stuff related works about good.
Now... I don't know about EMFAD device but if works in europe at that frequency you cannot obtain same results on 77500Hz there in the north america, so must look for Fort Collins 60Khz signal (indeed it's really strong signal so probably you'll receive it)... just you have to experiment using some LF receiver... I think, even a small dirty-cheap chinese made clock... tuned on WWWB frequency.

A thing to keep in mind is that in the clocks there are very selective filters for clearing out interferences... so if you see the clock receive the signal it's also cause of that: that's expecially true for urban areas with lot of electrical noise around and inside e.g. reinforced concrete buildings... where LF signals (if) arrive are very attenuated.
In open space... e.g. farm land the things are easy about it, though the coverage is not equal in any place... cause there are e.g. mountains that could create an obstacle to the ground transmission of the RF wave, but generally open space, far from power lines is the best scenario to receive that kind of signals.

Hope will hear good news from you.

PS: don't use gps for the test... gps takes clock signal from satellites... not from WWWB station on 60Khz... you need a cheap radio controlled clock...

Kind regards,
Max

No luck Max, I'll just go ahead with my plan to build a suitable portable backpackable TX, and then I shouldn't have to worry. Now, finding someone to do that little chore is another ................ My friend Tim Williams will/can do it, just me getting over to Louisana. Thanks for your help. Mike

Hmmmm... I see... strange you cannot receive that signal of WWWB.
Or maybe you receive it but not as good as required to use the device...

So I think you'll better find someone that will make that transmitter on frequency required.

I think the system works if right conditions matched... enough uniform EM field I mean... so you need a powerful TX and to put it somehow not too near your sensor/receiver device... that's cause it needs uniform field I think, like happens with normal usage in central europe where it's made.

Hope you'll find solution, if so please drop some lines here to let me know.

Kind regards,

I think Mike is talking about ELF submarine comms, not Loran. As I recall, the ELF transmitter in Wisconsin was shut down a number of years ago.

Hello,

Black Cloud , please let me know if you build that transmitter , i am facing same issue with my old model of EMFAD ,
