The Skyrider Panoramic is a spectrum display which portrays visually the signals in a selected part of the radio spectrum. It is connected to a receiver's converter at the input of the first IF amplifier stage. Connecting at a further point reduces the spectrum width. The SP-44 is designed for a receiver having an IF between 450 and 470 kHz. The signal being listened to is at the center of the display. Signals nearby in frequency are also displayed as pips of varying shape to the left and right of center. Pip shapes vary with the type of transmission. For example, the pips of SSB signals appear to come up from the base line and then drop back down again as words are spoken. AM signals will increase in height with modulation and their side-bands are often visible on stronger signals. CW (code) signals appear and disappear as very narrow pips as the carrier is turned on and off when keyed for code.
