Einstein’s Eclipse – Restored

On May 29, 1919, the Moon slid in front of the sun and forever altered our understanding of spacetime. It was “Einstein’s Eclipse.” Using his newly-developed theory of relativity, the young German physicist predicted that the sun’s gravity should bend starlight–an effect which could only be seen during a total eclipse. Some of the greatest astronomers of the age rushed to check his prediction.

More than 100 years later, Petr Horálek (ESO Photo Ambassador, Institute of Physics in Opava) and Miloslav Druckmüller (Brno University of Technology) have just released a stunning restoration of the photo that proved Einstein right. The original picture was taken in May 1919 by astronomers Andrew Crommelin and Charles Rundle Davidson, who traveled from the Greenwich Observatory in London to the path of totality in Sobral, Brazil. They were part of a global expedition headlined by Sir Arthur Eddington. Glass photographic plates from the expedition were typical of early 20th century astrophotography, colorless and a little dull. Read More

Brazil Bureau box returned undelivered….again

Once again the Brazil QSL Bureau parcel that we sent last year to the new PY address has been returned endorsed “UNCLAIMED”. I have attempted to email LABRE on 11 occasions and every email has gone unanswered by both LABRE and the QSL Bureau. I am very sorry that we have no option other than to no longer honour ANY Bureau requests for Brazilian radio amateurs and they should now request their QSLs by direct only.
Sadly every parcel sent to LABRE QSL Bureau since 2019 has been returned undelivered. It is time for Brazil hams to ask questions of their society.
I would also ask if you are in Brazil and can take up this matter up on our behalf we would appreciate it very much. We would of course like to be able to return to getting your bureau requests to you. Thank you

What is a ‘Standard ADIF’ – M0OXO OQRS

After getting errors when trying to upload QSL Cards requests using an ADIF file of your QSO’s, we are asked ‘what do we mean by Standard ADIF?’.

Many logging programs these days have so many ADIF fields that many are just wasted and clog up the system with very large and unrequired files. Log4OM has 90+ ADIF fields and so have many others. I have no doubt these fields are useful to some operators but for my purposes they are just unwanted. I don’t need to know your House Number on your Street, similarly I don’t need your Azimuth Heading. So what do I need for the purposes of using the adif file as part of your QSL request?

A ‘Standard ADIF’ is what you see below, just the bare bones of the contact QSO.

The only other fields we need are CALL, QSO_DATE, TIME ON, BAND, MODE, RST_RCVD, RST SENT. Also,

“Station_Callsign” Tells our OQRS where to upload the ADIF, and

“Operator” DXpeditions have multi operators so for this reason we ask for the operator call sign. This can be used for statistics and also for error chacking and is also added to the QSO label.

All other fields are just noise and this is why they sometimes can fail to upload to OQRS.

I hope that helps to clarify the situation for you.
