I have decided to copy this issue integrally, as it shows where they were dealing with. This is why this document is using so much data space, as I did not want to loose photo quality. Most of the articles could very well have been published in the late 1940s or early 1950s, without any changes! In my perception Radio Mentor periodicals are outstanding. Their articles are often sound. I cannot judge all references they mention, especially in respect to what occurred abroad. They rather frankly deal with what appeared in the enemy countries. Not in respect to the warfare, as this is hardly being noticed, but what happened in industry and that like. There is no trace of animosity against their actual enemy. Very noticeable is also their paper quality up to mid 1944 (a kind of glossy paper, although in 1944 paper quality tended to be less good). In contrast to the paper quality of, for instance, Funkschau. The abbreviation R.W. means Rolf Wigand, a very respected author and radio ham in those days (when you have activated this hyperlink please scroll a bit down the page). He disappeared very sadly in the final days of the war. Some say this was because he had tried to escape to the western Allied Forces, other say he was shot because he didn't follow instruction to stop. Regarding his articles, he was very orientated on what happened in the US, where he had been in the 1930s. Who in those days could travel so far away? He frankly described in an issue (see main RM page) the HRO receiver as well as the Hammerlund Super Pro; he also described the military communication receiver Schwabenland including its full schematic! Considering his US orientated interest, he might also have had enemies. However, the topics are definitely peace time subjects, maybe meant to ease the individual feelings, like most movies did in those days.


Some subjects dealt with: What happened abroad; Company information; Calculations of HF solenoids (coils); Calculations on directional microphones (Richt-Mikrofon); Spulenwindungszähler; Planmässige Fehlersuche (Werner Diefenbach): Ueber Funkentstörung (wie weit entstört werden muss); Bedeutung des Glimmers (Mica) und seiner Austauschstoffe für den Kondensatorbau; Theorie des Stimmgabelsummers!; Ein kommerzieller Empfänger Lorenz-Schwabenland, very rare that a military receivers including its full schematic is shown!; Ein neues Kristallmikrofon (Beyer); Symbole der Radiotechnik; Neue Bauteile: Spulenaggregat; Vierröhren Allstromsuper mit vier Bereichen*; Vorschläge zur einheitlichen Bezeichnung von Elektroden und Spannungen bei Braunschen Röhren; Tastoszillograph für Hochfrequenz; Klystron und Monotron; verbesserung der Empfindlichkeit des magischen Auges; Zerstörung von Gasleitungen durch vagabundierende Ströme und deren Vermeidung; Statische Dehnungsmessung mit Braunscher Röhre als Anzeigegerät

*This is curious, as in most German occupied countries radios were being confiscated. The German population
