Today we have reached a stage of affairs, where we may consider that we have reached nearly all our goals. The DMG5K is operating as it should once have been. Albeit, that we only consider: sending an audio signal tone which is being received. Bridging a distance of, say, a single meter as the transmitting energy being absorbed in a dummy-load. Two modules (Roman III and IV) are useless, as these were deliberately destructed and the other one had been changed for carrier-telephony in the early days of the German Bundespost. We start showing it functioning. Then we switch the system off and restart it again. The main power-supply HT being delayed about 12 to 15 seconds due to a delay system.
