The Channel Plus NF-469 RF low-pass filter blocks incoming cable TV channels 64 to 70 and off-air UHF channels 14 to 19, making room for modulated signals from a satellite receiver, VCR, DVD player, or camera. Once the channels are blocked, users with a 5400, 5500, or SVM series modulator can insert a signal onto any of three cable TV channels (65, 65, or 69) or three UHF channels (14, 16, or 18). The NF-469 couples to the coaxial TV input on either a splitter or an active video distribution device, such as a bi-directional video amplifier. In addition to blocking individual channels, the filter also blocks outgoing signals, such as cameras, from broadcasting back into the coaxial and outside the home. The device is a perfect response to the ever-increasing bandwidth taken up by cable TV.

Final stage of a B6122 or a BD272 HF transmitter class 'C' push-pull modulated RF amplifier, set up for 4MHz. Two ceramic enveloped BY1144L 125kW output valves feed the anode load, consisting of two single-turn coils centre-tapped to 11kV HT. The sender can be tuned to different frequency bands by mounting different coil-sets and adjusting the padder capacitors on the truck. Close observation reveals some hand-operated clamps. The movable output truck has a single-turn coil with the legs feeding a 328 Ohm (Z) balanced output via a TVI filter (405 line VHF TV!) and an aircraft-band filter. There's an apocryphal tale that the rectangular aluminium capacitor plate on the doors (far one visible) presented the same impedance as a Marconi engineer's head, and was fitted after tuning improved upon insertion of said head during the design stage! Output power is varied by moving the truck forwards and backwards, altering the coupling factor and so the reflected impedance.
