Being a regular SOTA operator (All Chasers are SWLs!) on HF I hear and work plenty of Polish stations.
Listening to Polski language contacts with operators from their own country (such as just now when I worked Matt@SQ9NIS on 20m SSB) it sounds like the Polish phonetic alphabet uses names, such as Pavel (for P) etc.
Interesting and a few years back I participated in the SP DX contest from the US using W6PNG.
If it’s on again this year do I call CQ Contest Wanda 6 Pawel Natalia Graznyia to make it easier for SP operators to get my call and presumably make it clear I’m in the SP DX contest?
The use of names as a phonetic alphabet in amateur radio is not unique.
It results from tradition and many other factors.
Names are also used by OK, OM, UT, LZ etc.
But every SP (OK, OM …) amateur knows english version of the phonetic alphabet, which is used in QSO with stations outside SP.
It’s always nice to hear a word in your own language during a QSO, like “Thank you”, “Hello” etc.
I also try to add something from myself in the language of my interlocutor. Sometimes one word can bring a smile to your face and build friendly relationships.
Polish father, English mother generally created zero opportunity to learn Polish growing up in London. A regret and my loss as i’d love to be fluent in Polish.
