How it operates

The MSK 24 is designed as a universal portable test receiver for TV, SAT and FM radio for both battery and mains operation. A built-in lead battery with 2.8 Ah and a plug-in power unit for 230 V AC are included with the receiver.

A microcontroller is responsible for controlling the unit, scanning the keyboard and displaying frequency and level on the LC display. Receiving frequencies are indicated in MHz. Levels are measured with a peak or average value detector and indicated digitally in dBìV or dBmV. Correction values are determined when levels are calibrated for the MSK 24. They are stored in an EEPROM. Precise level measurements can thus be made.

There is a bar display on the front display to help find transmitters. In addition, there is an audio tracking signal to facilitate aligning of the antenna as the display does not have to be observed.

The audio section with its built-in loudspeaker is capable of processing and reproducing various audio frequency satellite signals, audio frequency TV signals complying with the B/G, D/K, I, M1 (Japan) and M/N standards, as well as FM audio. NICAM and AM audio reproduction (L standard) is also possible.

All currently known requirements are covered thanks to an LNB supply voltage of 10-20 V / max. 500 mA with steps of 0.1 V, the superimposition of 22 kHz / 60Hz and the facility of sending DiSEqC or V-SEC commands.

The built-in TFT colour screen allows pictures to be assessed locally.
