AGC For uBitx

The agc circuit that we are using with ubitx has been used earlier with the bitx kits.

The agc circuit is build with Lm324.  The First IF stage is controlled with the agc.

It is suggested to start building the agc kit with first mounting the trimmers 10K 5K 50K and 202 ohms and soldering to the boards and adjust them as recommended below. After the trimmers have been calibrated they would need to be finally adjusted when the agc circuit is build and working, so let us start.

Step 1:

We require a multi meter for this adjustment for trimmers.
