INTERCEPT POINT OPTIMIZATION

)

Switch

This button may be used to set the optimum front

end characteristics of the receiver circuit for a very

strong signal environment. $vailable selections are

$03 1 low distortion amplifier), $03  -stage

low-distortion 5F amplifier), or I32 bypasses the

bandwidth of the 5oo¿ng ¿lter for the reception

mode. In this case, the selected bandwidth in

the 5.FLT column of the .ey Function 'isplay

glows green The unselected choices glow Blue).



Because the roofing filter is in the first IF, the

protection it provides against interference is Tuite

significant. When set to $UT2, the SSB band-

width is 6 kH], CW, 5TTY and '$T$, the band-

width is 3 kH], while $0 and F0 is 1 kH].

Switch

This button turns the IF 1oise Blanker on and off.

3ress this button momentarily to reduce short-dura-

tion pulse noise.

.ey Function 'isplay on the display.

[

AGC

]

Switch

This button selects the $GC characteristics for the

receiver. $vailable selections are F$ST, 0I', SL2W

in the

[

AGC

]

button for one second to disable the

$GC for testing or weak-signal reception).

DVICE:



The “$UT2” selection mode selects the charac-

teristic of the $GC for the reception mode. The

selected $GC characteristic will glow green in

the $GC column of the .ey Function 'isplay,

unselected characteristics glow Blue).



The $ttenuator may be used in conjunction with

the

[

IPO

button to provide two stages of signal

reduction when an extremely strong signal is be-

ing received.



If the $GC receiver-recovery time is set to “2ff”

by pressing and holding in the

[

AGC

]

button, the

S-meter will no longer deÀect. $dditionally, you

will likely encounter distortion on stronger sig-

nals, as the IF ampli¿ers and the following stages
