The receiver incorporates 8 tubes in its circuit and has four bands with continuous coverage from 540 KHz to 44 MHz. The first band covers from 540 KHz to 1680 KHz, the second band covers from 1.68 MHz to 5.4 MHz, the third band covers from 5.3 MHz to 15.5 MHz, and the fourth band covers from 15.5 MHz all the way up to 44 MHz. The Intermediate Frequency(IF) of this receiver is 455 KHz. The internal front panel mounted speaker is of the permanent magnet moving coil design that measures five inches across and has a voice coil impedance of 3.2 ohms. Received signals exit through a perforated section on the front of the unit. If headphones are to be used, the receiver requires a set with a low impedance. Besides listing the frequencies, the analog frequency display has been calibrated at the top of the dial from 0 to 100 and is used in conjunction with the smaller Bandspread scale which is also calibrated from 0 to 100. This type of calibrated system aids in accurate logging and quick re-tuning of the receiver. This radio uses the standard #47 bulb for the dial lamp and is housed in a sturdy metal cabinet. Both dials are working as the volume control. Probably needs to be repaired or tuned. United States of America (USA).
