!!! Set the same gain on both channels !!!

Do not forget to shortcut SLQ1& SLQ2 if no options are used

REV 2.3

If you want to use spectrumlab to have a larger bandwidth

These resistors reduce the Q factor of the antenna system.Noise from adjacent frequency may disturb LR.

the resistors may be placed with a value of 1K.

(Current version / May 2008)

R200 & R300 must not be installed.

Daniel Verschueren

The experience showed us that it would be preferable tohave the tuning frequency at 10KHz.

How to set the Gain of the amplifiers ?

R203+R204+R205+R206

When you will set or change the gain of the amplifiers,

you can close or open the small J switches.

There are 15 possibilities of gain

To localise the J switch,

reverse the PCB and look for the inscription “SOLDER”.

The J switches are localized by the red rectangle.
