From July 1, 2016, the Danish postal service has (again) raised the postage for letters abroad.
DKK 25.00 for a 50-gram letter. At today’s exchange rate it is around 3.6 USD.
This means, unfortunately, that I am compelled to require at least 3 USD (greenstamps) enclosed with your QSL as return postage for direct QSL.
As of JULY 1, 2017 the Danish Post has discontinued ALL sales and redemptions of IRCs.
So please, NO IRC’s, I can’t use them.
If your letter contains less than 3 USD or IRC’s, I’m forced to reply via the bureau.
I can only recommend that all radio amateurs join Logbook of The World (LoTW). It is free to be registered at LoTW, only one time expense is for the postage for the letter to ARRL containing a copy of your license certificate and the ongoing cost of your Internet connection.
