| (1) SPEAKER
|
| Internal speaker |
| |
| (2) POWER
|
| This is the main
ON/OFF switch for the receiver. When the POWER switch is in the OFF position,
on/off control may be exercised by the clock timer. See the "Operation" section
for details. |
| |
| (3) PHONES
|
| This is a standard
1/4" headphone jack. When the headphone plug is inserted into this jack, the
internal speaker is automatically cut off. The audio output impedance is 8
ohms. |
| |
| (4) REC |
| This miniature phone
jack is for recording purposes. The output level is approximately 100 mV
(fixed), irrespectivee of the setting of the AF GAIN control. |
| |
| (5) MODE |
| This control chooses
the desired mode: |
| LSB/CW |
Use this position for lower
sideband (LSB) and Morse Code (CW) reception. |
| USB |
Use this position for upper
sideband (USB) reception. This position may also be used for CW reception, if
desired. |
|
|
| AM N |
Use this position for narrow-band
AM reception. Under conditions of extremely heavy adjacent frequency
interference, this position of the mode switch may allow AM reception where a
wider mode would be unusable. There will be some degradation in fidelity in the
AM N position, however |
| AM M |
For all-around AM reception, the
AM At position of the mode switch may be used. Because of the wider bandwidth,
the fidelity on the incoming signal is much better than with the AM N
filter. |
|
| AM W |
Under clear band conditions. the
AM W provides the widest bandwidth and best fidelity. |
|
| FM |
This position selects reception
of FM signals. |
| |
| (6) AGC |
| This switch allows
selection of the optimum AGC (Automatic Gain Control) decay time. The SLOW
position is normally used for AM reception, while the FAST position is normally
chosen for Morse Code (CW) reception. For SSB reception, the optimum position
is determined by band conditions and the adjacent-frequency interference
level. |
| |
| (7) NB |
| This switch, when
pressed, activates the noise blanker for reduction in the level of interfering
pulse-type noise. |
