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.
