By keying the transmitter tube, meters in the receiver tube were made to read in accordance.

For the follow-on system, the frequency was raised to 200 MHz, the limit for transmitter tubes and other components at that time.

During the withdrawal some German soldiers had been ordered to dynamite the station, but a station engineer persuaded them to shoot holes in the transmitter tubes instead.

"The transmitter tubes are smashed to fragments."

"You think it would be useless to attempt to duplicate the space-shift signal transformer and the transmitter tubes?"

We can't repair or duplicate the smashed transmitter tubes or hyperspace transformer.

K38HE went off the air couple of times after a transmitter tube broke in the transmitter and returned to the air on October 9th,2009.

However, many specialised Russian tubes, such as special military or transmitter tubes, do not follow the above convention.

The frequency of 200 MHz was the highest possible with existing transmitter tubes and other components.

An arrangement of new transmitter tubes was used, giving near 50 kW peak-power with a 10 μs pulse-duration.
