\nSpojen\u00ed bylo uskute\u010dn\u011bno z Kanady do Anglie mezi stanic\u00ed Larryho Kaysera, VA3LK a stanic\u00ed Lawrence Mayheada G3AQC. Pro nezasv\u011bcen\u00e9 v provozu na p\u00e1smu 136 kHz mus\u00edm upozornit na to, \u017ee nejde o klasick\u00e9 spojen\u00ed p\u0159i kter\u00e9m se stanice sly\u0161\u00ed. Vlastn\u00ed spojen\u00ed prob\u00edh\u00e1 v m\u00f3du CW, kde te\u010dka je dlouh\u00e1 90 sekund a \u010d\u00e1rka 180. Ke dek\u00f3dov\u00e1n\u00ed je pot\u0159eba speci\u00e1ln\u00ed program jako nap\u0159\u00edklad ARGO, kter\u00fd V\u00e1m umo\u017en\u00ed „vid\u011bt“ co protistanice vys\u00edl\u00e1. Tento druh provozu je naz\u00fdv\u00e1n jako Pomal\u00e1 telegrafie nebo QRSS. Dal\u0161\u00edm druhem provozu, kter\u00fd je mo\u017en\u00e9 v p\u00e1smu 136 kHz pou\u017e\u00edt je telegrafie s rozd\u00edln\u00fdmi kmito\u010dty pro te\u010dku a \u010d\u00e1rku ozna\u010dovan\u00e1 jako DFCW (Dual frekvency CW). G3AQC pou\u017eil na vys\u00edlac\u00ed stran\u011b jako koncov\u00fd stupe\u0148 audio zesilova\u010d 1kW, kter\u00fd v p\u00e1smu 136 kHz je schopen dod\u00e1vat a\u017e 400W v\u00fdkonu do cca 15m vysok\u00e9ho vertik\u00e1lu, kter\u00fd vyz\u00e1\u0159\u00ed p\u0159ibli\u017en\u011b 350 mW. Larry VA3LK pou\u017eil 100m semi-vertikal , kter\u00fd vyz\u00e1\u0159il p\u0159ibli\u017en\u011b 5W.
