This has so many errors, it’s embarrassing!
I greatly value your opinion Allen, I appreciate your concern and I promise to take your notes into consideration if you point out any mistakes you see. I admit it is likely that some are translation errors as well. Thank you very much for the comment!
What is “es”?
“73” means “best regards”
“best 73s” means “best, best regardses”
So many more! Take it down!
“What is “es”?” – its meaning is spelled out – and, also. You can see it.
“73” means “best regards” – that’s exactly how he wrote it. In Bulgarian you also say “best wishes”, which makes the use of 73s not very logical, and my mother’s language is Bulgarian, I love it and use it whenever I have the chance. And as a radio amateur, I am tolerant of all languages.
“best 73s” means “best, best regards” – yes, it could be accepted, but the two expressions are written separately, I don’t see the point of writing them together. This is somewhat a matter of style – I personally would never use “best 73s” for the reason of my note above. I would prefer to pass on 73 ES BEST DX – best wishes and good far countries (QSOs). But should I write the same abbreviations in this way? In my opinion – no, and I have not done it.
“So much more! Take it down!” – so far I haven’t seen an any single error and you’ll excuse me, but I don’t intend to delete this page at all. On the contrary, I expect many enthusiasts like you within the amateur radio spirit to chime in and have their say on it. So together we will make a wonderful tool for young radio amateurs. Also, why not for the older ones – to remember.
Let’s keep the radio amateur spirit alive!
73 and see you again! I would love to hear you on the air too, my favorite modes are CW, FT 8, FT 4 and the other digital modes.
