89) AlP(Advanced Intercept Point) key
Use AIP when good signal reception can not be
obtained. When switched on, it reduces
interference from strong signals.
When
the frequency falls below 9.5MHz,
AIP turns
on automatically. AIP can be turned off on individual
bands below 9.5MHz by pressing the AIP key.

@) AGC key
Pressing this key toggles the AGC time constant
between SLOW and FAST.
FAST
: For CW, FSKand data communications.
SLOW: For SSB and AM.
Note
This switch is disabled during FM operation.
42 NB 1/2 key
NB1: For pulse type noise, such as that
generated by automotive ignition systems,
select NB 1.
NB 1 will not help to eliminate
atmospheric or line noises, only pulse
type noise.
The NB2 only works on woodpecker type
noise.
Noise blanker 2 is used for long duration pulse noise,
like the "woodpecker". To reduce "woodpecker"
radar noise interference, select NB 2 (NB 2's
effectiveness depends on the specific type of
interference). If you use NB 2 for short duration pulse
noise, the receive signal may become distorted,
making it difficult to hear.
Unfortunately no noise blanker can remove all
different types of interference; but the two noise
blankers that have been provided in the TS-
4505/6908 are effective in most cases.
If there is no "woodpecker" present, turn NB2 off.
43 PROC key

power
output will
increase
when the PROC
is turned ON during SSB mode
operations.
48 Μ.ΟΗ/ΝΕΟ CH control
This control is used to select the desired
memory channel during Memory Channel
Operation.
This control is also used to change the
frequency in 10 kHz steps during VFO
operations.
The control is also used to select the desired
power on function you wish to change. See
section 4-11-15.
45) NOTCH control
The NOTCH function is used to reduce or
eliminate heterodyne, or CW type signals. The
NOTCH filter will not be effective against SSB,
AM or FM type signals.
