Hi Gary,

 

Well, is a long story so far , after the=20 initial responses, there was no real follow up, periodically, I have sent=20 invites to various centres of excellence with quite mixed=20 results

 

The main problem would appear to  be that not everyone is interested in= =20 500  and secondly , confusion=20= is=20 generated with the apparent desire to = ;=20 establish a permanent beacon chain as opposed to the original free fo= r=20 all (quite literally ) open propagation experiment, using simple beacons and= =20 reception stations, both active and passive . This also has clashed with a m= ove=20 to reduce beacon activity below 20 =20 MHz , so  perhaps in hi= gher=20 circles the concept has become =91hot=92,   a need to  demonstrate experimental activity on=20 what is a =91experimental band=92.

 

As can be seen from the recent posts, the=20 problem still exists, in that qrss may produce a trace at the other end  but as to who it is, is still t= he subject=20 of debate ! and even so , no real data is extracted that my be used for=20 scheduling a qso  or pond-hopp= ing=20 attempt  or semi local qso=92s= . From=20 the published traces, we do seem to be looking at flash propagation but with= out=20 any data recovery it hard to say ?  = ;I think the 6 hour whisper transmission=20 is the closest yet to  a docum= ented=20 =91run=92 ?

 

Unfortunately, the audio processing and=20 data recovery  aspects of the=20= system=20 are out side the programming skills of =91my=92 circle of friends and as suc= h I am=20 not able to  instigate the cod= ing of=20 the system, as you can see from the original work, the system is feasible an= d=20 would of provided quite a few  pond-hopper =91qsl=92 cards this winter=20 alone, whilst reducing the carbon foot print by much reduced transmitter dut= y=20 cycle time !

 

Thanks for the follow up, but as of yet,=20 with recognition to  the origi= nal=20 coding inputs , there is no system at the moment.=

Hi Graham,=20 LF,

 

What=92s the latest=20 with the 500KHz =93Big Beacon Project=94?

 

I have read the=20 recent update to the document at http://groups.google.com/gr= oup/uk500khz/browse_thread/thread/ea4cf6c1a87a0ed6

 

Are you still=20 looking for suitable beacon software, or is there some other=20 holdup?

 

73,=
