Install RF gain control R77 to the pads marked "RF Gain" using discarded leads from
previously installed components
[ ]
Install capacitors C93 and C94.
Your PCB should look like that shown in the next figure.
Test – Connect a speaker or headphones to the "SPKR" jack. Apply power to the PCB.
Connect an antenna to the lower pad where capacitor C95 will be mounted. Alternately peak
trim capacitors TC3, TC4 and TC5 until the band noise or a received signal is the loudest.
Adjust R77 to verify the RF gain can be reduced.

Receive Incremental Tuning (RIT)
[ ]
Install the 2N7000 MOSFET at Q24.
[ ]
Install diode D11. This diode (a MV209) looks like a transistor with markings on it but with
only two leads.
[ ]
Install resistors R42, R43, R44, R50, R51 and R57.
[ ]
Install RIT control R53 to the pads marked "RIT" using discarded leads from previously
installed components
[ ]
Install capacitors C40, C70, and C71.
