ILER-DDS V2.1 VFO/DDS.

You can mount the resistors and the capacitor on a small perforated board or you can mount the
components "in the air" directly on top of the ILER board.
Note:
The ILER CAG circuit does not start to act until the signal does not exceed 3-4uV (S-5)
this is inherent to that circuit.
CONNECTING THE S-METER INPUT TO OTHER TRANSCEIVERS
You should study the available voltage of your receiver that you can use as a reference for the ILER-
DDS S-Meter and adapt it if necessary.
Remember that in no case can it exceed 4.9V.
Normally the
receiver's AGC voltage is used. This can be directly or indirectly proportional to the reception signal.
Choose the corresponding calibration mode in the "CAL S-METER" menu ("DIRECT S-METER" or
"REVERSED S-METER").
You can also experiment by building a small adapter circuit that takes audio signal (before volume
control) and converts it into a suitable voltage level for the S-Meter input of the ILER-DDS.
Note: EA3GCY Kits is not responsible for the failures caused in ILER-DDS due to improper use.
