Ein schöner Bausatz und ein schönes Geschenk für einen Anfänger

Endlich gibt es mal einen schönen Bausatz für Amateurfunker. Sehr einfach aber ein praktisches Tool für einen Anfänger und auch ein tolles Geschenk. Ich muss meinem Vorredner recht geben, die Lötstellen sind etwas schwer zu löten. Ich konnte aber nichts von einem Lack entdecken. Die großen Widerstände nehmen sehr viel Hitze weg, man muss ein wenig mehr Geduld haben. Beim löten empfiehlt es sich einen starken Lötkolben zu verwenden. Ansonsten in die Anleitung schauen! Ich habe es zuerst ohne versucht und bin schier verzweifelt. In der Anleitung gibts einen guten Tipp wie man die Widerstände besser auffädeln kann! Ein schöner Bausatz und eine schöne Werbung für ein tolles Projekt: 50ohm.de

Als Produkt gut, als Projekt leider nicht

Der Dummy Load ist als fertiges Produkt toll und tut was er soll. Das Löten war leider ziemlich frustrierend, weil sämtliche Pads mit Lötlack überzogen waren, der erstmal angekratzt werden musste, damit man eine ordentliche Verbindung hinbekommt.

Our feedback: Hallo David, das ist natürlich nicht schön zu hören. Was genau meinst du mit Lötlack? Kannst du uns dazu ein Foto per Email schicken? Selbstverständlich bekommst du bei einem fehlerhaften Produkt einen Ersatz von uns! Ich hoffe du hattest trotzdem etwas Spaß beim Löten.
