Hi Gary,

 

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

 

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

 

As can be seen from the recent posts, the problem still exists, in that qrss may produce a trace at the other end  but as to who it is, is still the subject of debate ! and even so , no real data is extracted that my be used for scheduling a qso  or pond-hopping attempt  or semi local qso?s . From the published traces, we do seem to be looking at flash propagation but without any data recovery it hard to say ?  I think the 6 hour whisper transmission is the closest yet to  a documented ?run? ?

 

Unfortunately, the audio processing and data recovery  aspects of the system are out side the programming skills of ?my? circle of friends and as such I am not able to  instigate the coding of the system, as you can see from the original work, the system is feasible and would of provided quite a few  pond-hopper ?qsl? cards this winter alone, whilst reducing the carbon foot print by much reduced transmitter duty cycle time !

 

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

Hi Graham, LF,

 

What?s the latest with the 500KHz ?Big Beacon Project??

 

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

 

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

 

73,
