A (very) short note on the South African TECO Set of WWII vintage |

Although I believe it was made in South Africa, I have
been unable to establish exactly where and by whom, but it was evidently
a 'stop gap' measure given the UK inability to produce No. 18 sets for
any forces other than their own, and was used in a similar role by South
African forces in Abyssinia and the Western Desert in the early part of
the war.
It was housed in a wooden box about a foot wide and 18ins high with folding metal legs to stand on and a one piece battery supplying both LT and HT in the bottom half together with Morse key, headphones and microphone. The TX side consisted of a modulated oscillator and the RX comprised a simple regenerative circuit and audio amplifier. Readily available commercial components were used, as can be seen from
the pictures. A MkII version included slow motion dials to assist in tuning and a few other minor refinements. Specifications: Teco pack set
