The Hallicrafters CRX-2 is a 10 tube, single band, dual conversion, FM receiver. It has a frequency range of 151 MHz to174 MHz. The radio has two different intermediate frequencies(I.F.) which are 455 KHz and 10.7 MHz. The front panel controls are as follows from left to right, the Main Tuning knob, On/OFF and Volume control, Electronic Squelch control, and three position Crystal/Main tuning selector knob. The radio also features a Vernier tuning control on the same shaft as the main tuning knob. The separate Vernier control for the main tuning knob allows the operator to quickly move to a different frequency using the main tuning knob and once a station is found, the operator can then fine tune the station with the Vernier control for the best reception.
The radio also has a space for two optional plug in CR-23/U type crystals for quick tuning of a popular frequency. The CRX-2 features a built in speaker behind the front panel. This loudspeaker which faces out towards the front of the unit is of the permanent magnet moving coil design. Received signals exit through a perforated section on the front of the unit. The power consumption of the radio is 51 watts with a power source of 117 volts AC at 50 to 60 cycles. The input power source should be in the range of 105 to 125 volts AC at 50 to 60 cycles. If an external speaker is used, Hallicrafters suggest that it be in the range of 3 to 4 ohms.
The tubes are as follows, a 6ER5 = RF Amplifier, 6BL8 = 1st Mixer & Oscillator, 6BL8 = 2nd Mixer & I.F., 6BL8 3rd Mixer & Crystal Oscillator, 12BA6 = I.F., 12AT7 = Crystal Oscillator, 12BA6 = I.F., 6DT6 = Detector, 6BL8 = Squelch & 1st Audio amplifier and a 12AQ5 as the Audio Output. The rectifier consists of two silicon 1N3194 diodes. The dimensions of the radio are 13 1/2 inches wide by 5 3/4 inches high by 8 inches deep. The CRX-2 weighs in at 15 1/2 pounds.
The photograph on the right is of the back of the receiver. This picture displays the tube compliment and some of the other major components that are found on the top of the chassis. Starting at the left, the back panel plugs and switches are as follows, AC power cord, a red colored internal/external speaker switch, external screw terminal speaker connections, ground connection, an RCA style antenna connection which is located underneath the paper sticker and an SO-239 connection on the right. Hallicrafters recommends that a coaxial transmission line of between 50 to 75 ohms should be used for the SO-239 connector.
A very similar receiver is the Hallicrafters CRX-1 which also receives only in FM mode and covers the frequency range of 30 MHz to 50 MHz.
