Icom IC-736 (IC 736 IC736) Speed-up the ALC
|
| |
I got a IC 736 in December 1994. It is a good rig but had also a
lot of misstate. After a time of measuring and testing I found the ALC for
transmitting is to slow. So I jacked the circuit why is so. I found a C-R
delay in the way from the ALC on the Main Unit. It is the C287(1uF) and the
R305(150Ohm). The C change or put out is not very easy. So I change the
Resistor 305 in to smaller one. But the result was not better. The best
result I had without it! So the C-R combination is not in the work for the
ALC. The Resistor 305 is very small but it is easy to put out. On the
Resistor is the number 151 printed (150Ohm) but you mast find it on the
circuit.
To be wide TX you mast only cut the Diode D15 on the Logic Unit.
The IC 736 works very well at the last half year so I send it out in the
PR-news now.
