R&S SK080 AM transmitter demo with big modulator

Radio Delta team refurbished this beautiful vintage 1959 Rhode & Schwarz SK080 AM broadcast transmitter. We used this transmitter in the past.

The power is about 600watt carrier but in practice half much more. The SK080 has a nice internal modulator with 2*QB3/300 tubes.

The SK080 could modulate around 800 watt nom. Many dutch pirate stations use the smaller SK010. With external modulator this transmitter can modulate around 130 watt nom., with a brilliant modulation.

The SK family was in used by the German Army during 60’s and beginning 70’s. During the 80’s and 90’s this army surplus was sold to handlers.

It was in the past rather simple to buy such a gear in Germany and Holland. Later became the SK1 (1 kW max carrier power AM, + USB and LSB ) popular. But there mintage was much much less. R&S transmitters have the quality of a “mercedes” car.
