Extended Control Cable


oh6bi
 

Hi All !

Finally I bought FC40, I have used Icoms AH3 many yers and because of
good results with it I decided to by FC40 for my FT897.

FC40 will arrive to day and first I need to extend the control cable.
Anyone experience ? Is it needed to be shielded or not ? How long I can
make it ? How much FC40 needs Voltage and Current for the tuning. With
IC AH3 I have had up to 20m long cable with wire size 2x0.5 mm.

What about Ground connection ? Is it necessary to use separate ground
cable between rig and tuner when the distance is longer than 5 m ?

First I am goeing to test FC40 with my existing inv L antenna, vertical
part 21 m and horisontal part 41 m , total 62m (204 ft).
To compare existing IC706/AH3 and new FT897/FC40 with same wire + Gnd.

I am goeing to use Yaesy system at my summer cottage with long wire ,
length more than 100 meters .

Any addvises before starting the tests ?
