|Opis:||SOLID STATE AMATEUR AND SHORTWAVE RECEIVER|
The Lafayette Model HA-600A is a sensitive solid state superheterodyne receiver designed to meet the needs of the Radio Amateur as well as the most demanding short-wave listener. The large illuminated side rule tuning dial clearly and accurately indicates receiver frequencies from 150 KHz to 30 MHz in five bands. For extreme accuracy, a band spread tuning dial is incorporated with direct dial calibrations on the 80, 40. 20, 15 and 10 meter amateur bands. A 0-100 logging scale is also included on the band spread dial to assist in logging other than amateur band frequencies. Through the use of two separate tuning dials, optimum read-out and operation is provided. The HA-600A is designed to receive CW (code), AM (phone) and SSB (single sideband) within the frequencies covered by the receiver. When receiving SSB or CW signals, the variable BFO (beat frequency oscillator) may be used to select the desired sideband or adjust the pitch of the CW signal. The receiver employs a tuned RF and Mixer stage to give maximum sensitivity and a high signal-to- noise ratio, while two Intermediate Frequency stages and a mechanical filter provide a high degree of selectivity. A product detector operating in conjunction with the BFO is employed for CW and SSB operation, while a separate diode detector is used for AM reception. The all transistor design of the receiver offers all the advantages expected from solid state circuitry - - instant operation, low current consumption and cool operation. The receiver is designed to operate from 105-120 volts 50/60 Hz AC. The antenna input is designed for use with unbalanced type lines of 50-400 ohms impedance. An antenna trimmer control provides the required matching of the antenna to the receiver. A tape recorder output as well as audio outputs of 8 or 500 ohm impedance are provided on the rear panel.
