T/R switch 220/240 VAC
Ameritrons self-contained QSK-5 switch uses electronic PIN diode switching to give you lightning fast QSK operation from nearly any HF linear amplifier. It lets you use your linear amplifier for high power QSK CW, for Packet, AMTOR and any mode requiring extremely fast switching between transmit and receive.
Installation is simple. All you do is plug in a few cables to start enjoying QSK -- theres no complicated internal wiring. The worlds most advanced QSK switch has new technology thatll make your amplifier last longer and prevent TVI, RFI and key clicks.
Ameritrons exclusive AmpSaver (available in QSK-5PC) completely turns off your power amplifier tube current between dots, dashes and words! This new QSK technology gets rid of unwanted power dissipation that causes damaging heat. Your expensive amplifier runs cooler so every component in your amplifier lasts longer.
Our exclusive SureSwitch handshaking prevents "hot switching" RF power. Prevents TVI, RFI, key clicks and possible damage to your amp. The QSK-5 is six times faster than a typical mechanical vacuum relay "QSK" switch that can just barely keep up with QSK transceivers. As transceivers get faster and better, mechanical switching just wont be able to switch fast enough. Unlike noisy mechanical vacuum relays, the QSK-5 is extremely quiet -- theres no relay chatter to keep you from enjoying QSK.
You won't have to pay for QSK again if you buy another amplifier. Unplug the QSK-5 and use it with your new amp. Handles 2500 watts PEP and 2000 watts CW in normal amateur service when SWR is below 1.5:1. Handles 750 Watts on continuous carrier modes such as RTTY, SSTV, and FM. The optional CF-5cooling fan allows sustained operation at 1500 Watts in any mode. Use with positive voltage keying up to +25 volts.
