I do not have, or need, a QSL manager and QSL personally by the following methods only:

Logbook of The World (LoTW) every two or three days or immediately after a run of any mode.

Direct cards are replied to immediately.  QSL cards in the Falklands are expensive, the postage is still reasonable.  One IRC is OK.  US$2 also covers all costs with a little surplus which I use to cover the cost of those who are too poor to include return postage, as long as there are not too many of these.
 
I am a member of the Radio Society of Great Britain (RSGB) and reply to received bureau cards via the RSGB QSL bureau service.  Incoming bureau cards are received from many sources and are usually turned around within 3-4 weeks.

SWL cards are replied to but please try to get the details correct.  I receive some which are attempts to QSL a cluster spot.  Correct date, band, time, mode and a couple of consecutive QSO’s is good.

I do NOT have any interest in eQSL or other methods.

My address above is correct.  Card requests addressed to “Islas Malvinas” can fall in the waste bin.

73 and good DX.
