     OPERATING WINLINK HF PORTABLE   Last Thursday 24 June 2021, I operated WINLINK (HF VARA 4.4.3 aka poor man's PACTOR) and later some FT8 on 20m with my IC-705, a 57cm LOOP and a GPD 6inch pocket PC at St Mary's Island next to it's Lightouse near Whitley Bay NorthEast England. This was a BOTA (Benches On The Air Hi hi hi!!!) operation! Here is a description of my setup: Everything fits in the backpack including the mini laptop, the mini loop, a backup 25Ah battery for the PC, an Elecraft T1 ATU with 9:1 balun and 10 meters cable, 2 spare batteries for the IC-705, a small SPX-100 antenna for the radio and a small 40cm tactical antenna for 2m/70cm bands. So I have 4 antennas in there, just in case! There is enough room for a 4.5 meters fiberglass rod on the side pocket which can be used for supporting the 10m wire and Elecraft T1 ATU, next to the SPX-100 antenna! The mini LOOP ANTENNA is an early ALPHA LOOP which I bought some years ago for $120 including postage to Greece

World Amateur Radio Day

Every April 18 , radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day. It was on this day in 1925 that the International Amateur Radio Union was formed in Paris. Amateur Radio experimenters were the first to discover that the short wave spectrum — far from being a wasteland — could support worldwide propagation. In the rush to use these shorter wavelengths, Amateur Radio was “in grave danger of being pushed aside,” the IARU ’s history has noted. Amateur Radio pioneers met in Paris in 1925 and created the IARU to support Amateur Radio worldwide. Just two years later, at the International Radiotelegraph Conference, Amateur Radio gained the allocations still recognized today — 160, 80, 40, 20, and 10 meters. Since its founding, the IARU has worked tirelessly to defend and expand the frequency allocations for Amateur Radio. Thanks to the support of enlightened administrations in every part of the globe, radio amateurs are now able

Αυτός είναι ασύρματος! Μπορεί να καλύπτει όλη την υδρόγειο χωρίς κενά. Ακόμη κι όταν ο ένας χειριστής είναι στο Βόρειο Πόλο κι ο άλλος στο Νότιο Πόλο, έχουν επαφή όποια ώρα θέλουν βασιζόμενοι σε 66 δορυφόρους χαμηλής τροχιάς με καθυστέρηση το πολύ 500mS.  Τι γεωστατικοί δορυφόροι στα 36.000 χιλιόμετρα, κάτοπτρα του ενός μέτρου, διπλά και τριπλά coaxial, κουτάκια και παρακουτάκια με ενισχυτές, κονβέρτερς, ταλαντωτές με GPS μέσα κι έξω από το σπίτι και τέτοιες τρίχες!  73 de SV1UY/M0SUY

Πολύ ενδιαφέρον τρισέλιδο άρθρο του Ian Poole G3AWX σχετικά με τη διάδοση των βραχέων κυμάτων. Σε τρείς σελίδες τα λέει όλα. Καλό είναι να το διαβάσουμε. 73 de M0SUY/SV1UY
