Collins Equipment - HF Receiver 75-A-4
Collins 75A-4 Receiver is designed expressly for Amateur operation on the seven HF bands - 160, 80, 40, 20, 15, 11, and 10 meters. The Receiver retains the time-proven features of the earlier 75A Series; notably, excellent image rejection through the use of double conversion; precise dial calibration and high stability provided by the permeability tuned, hermetically sealed Collins VFO and the crystal controlled first injection oscillator; and ideal selectivity produced by Collins Mechanical Filters.
