Controls & Indicators
PHONE JACK. For earphone reception or external speaker (8 ohms). Insertion of phones or speaker jack disconnects internal speaker.
OFF – VOLUME. Turns radio on and off and adjusts audio output level.
BAND. Selects the proper range of received frequency.
MODE. Selects mode of reception. AM (amplitude modulation), USB (upper single side band) and LSB (lower single side band). CW (continuous wave) may be received on either USB or LSB position. The mode selector selects the proper detector (product detector for SSB and diode detector for AM) and IF selectivity filter.
CLARIFY. Provides ultra fine frequency adjustment (approximately ±3 KHz range). This control is used primarily on SSB and CW signals for setting the pitch or sound accurately after the station has been roughly tuned in. It should be in the center position before any tuning is commenced.
PILOT LAMP SWITCH. On AC operation the pilot lamps are always lighted. The pilot lamps are normally extinguished on battery operation to conserve battery life. Pushing this momentary action switch turns on the pilot lamps.
MHz. Tunes the MHz range of the received frequency. This control tunes the smaller inner dial and is adjusted for the center of the desired MHz range.
SIGNAL METER. Indicates relative RF input signal level.
PRE-SELECTOR. Adjusts receiver RF tuned circuits for proper reception of signal. This control is tuned for maximum signal or noise at the selected frequency.
KHz. Tunes the kHz range of the receiver. This control turns the large outer dial and is adjusted for the proper frequency as displayed on the graduations. This dial has a graduated scale from 000 to 1000 and is read as 0 to 1000 kHz or .000 to 1.000 MHz.
FREQUENCY DISPLAY. Indicates tuned frequency as explained in MHz and KHz controls. The inner dial indicates MHz range and the outer dial indicates kHz reading. As an example: 5.750 MHz.
