FRO kurs i Höllviken


Nu har några av Katrineholms radioamatörer varit på FRO kurs i Höllviken, det handlade om grundutbildning av signalister. Man kan lugnt säga att det var väldigt lyckat och lärorikt. Själva boendet går inte av för hackor och man kan gotta sig rejält i den goda maten och den trevliga puben, rummen var mycket fina och det kändes som man var på rena semesteranläggningen. Själva kursen var väldigt intressant och lärarna var mycket duktiga och kunniga.


Här är det dags för resning av civilförsvarets höganten och det krävdes hjälm, risken att få nåt i skallen finns ju alltid. Att få upp en antenn snabbt kräver bra samarbete och jag tycker det gick ok (jag SA5BHL till höger i vita t-shirten)


Här reser ett gäng högantenn ett som ansågs som svårast, dom fixade det bra och snabbt.


Två av lärarna som lärde ut hur man tar ut kordinater på kartor med hjälp av UMT systemet.


Slutövningen bestog av ett scenario med översvämmning av ett antal orter och det handlade om att skicka meddelanden via radio och göra det på rätt sätt, samt att läsa kartor och markera olika händelser.


På kvällen så blev det snack i puben här SM5TEY, SA5YLX, killen i mitten har jag inget namn på men han tillhörde Hemvärnets insatsstyrka. Till höger SM5TAH.


Man kunde verkligen njuta på kvällarna och titta på den fina solnedgången över Öresund.

Jag skickar en hälsning till alla som deltog på kursen och till lärarna och tackar för en underbar vecka.

Vintage Radio Shack Realistic Modulaire 8 Track Stereo

This is an old Radio Shack stereo I found in the trash. I was surprised how good it sounds for what it is. It is just playing through small 5″ Sony bookshelf speakers, and I can’t believe how good the bass can be. I will probably rebuild this one if it cleans up well.
