Digitala moderna JT65 och JT9 är fantastiska – del 1

K1JT Joe Taylor är inte bara radioamatör. Han fick även 1993 års Nobelpris i Fysik, som öppnade upp nya vägar kring forskningen om gravitation. Han är numera pensionär (född 1941) och ägnar en hel del tid och experiment kring lågeffektsändningar med utveckling av programvaror och modulationssätt för att kunna överbrygga stora avstånd med otroligt svaga signaler. Tack vare Joe Taylor har [...]

Fjärrköra generation 4 SDR-radio över nätet

Undertecknad har under våren varit runt på ett ganska stort antal klubbar och sammankomster för att hålla lite föredrag. Denna gång var temat ”dagens radioteknik”. Alltså inte morgondagens eller gårdagens, utan dagens teknik, den teknik som vi har runtomkring oss idag. En realitet är att SDRadios ger oss garanterat bättre prestanda än de bästa analoga [...]

Vi kunde då och fortfarande nu konstatera att det inte finns någon mera effektiv lösning för att på ett enkelt och inte minst effektivt realisera en komplett lösning för att bygga en fjärrstyrd radiostation. Jag gick [...]
