Ameritron QSK-5 High Power Transmit/Receive Switches QSK-5
Amplifier Switch, Self-Contained, High Speed T/R Relay System, handles 2,500 watts PEP, 120 Vac, Each
Ameritron QSK-5 high power transmit/receive switches use electronic PIN diode switching to give you lightning-fast QSK operation from nearly any HF linear amplifier. They allow you to use your linear amplifier for high power QSK CW, for packet, AMTOR, and any mode requiring extremely fast switching between transmit and receive. These switches feature new, advanced technology that'll make your amplifier last longer and prevent TVI, RFI, and key clicks. Ameritron's exclusive AmpSaver completely turns off your power amplifier tube current between dots, dashes, and words. This gets rid of the unwanted power dissipation that causes damaging heat, letting your amplifier run cooler so that every component inside of the amplifier lasts longer. Their exclusive SureSwitch handshaking prevents hot switching RF power, TVI, RFI key clicks, and possible damage to your amp. Ameritron QSK-5 high power transmit/receive switches are six times faster than typical mechanical vacuum relay QSK switches that can barely keep up with QSK transceivers. They can handle 2,500 watts PEP and 2,000 watts CW in normal amateur service when SWR is below 1.5:1, and they can handle 750 watts on continuous carrier modes, such as RTTY, SSTV, and FM.
