Ramsey Electronics FR146 manual Install C8, .001 uF marked .001, 102, or 1 nF

dot, or notch. Before soldering, make sure that the IC or socket is perfectly fflat against the top of the PC board. Install U1, the SA602, in accord with the preceding directions.

❒19. Install FL1, the ceramic filter. This component looks like a capacitor with 3 leads and may be installed either way.

❒20. Install jumper wire JMP4. Use a scrap component lead wire bent like a staple that connects the two PC board holes. Jumpers act as "bridges" over PC board traces underneath.

❒21. Install C8, .001 uF [marked .001, 102, or 1 nF].

❒22. Install C10, 15 pF.

❒23. Install R7, 10K. [brown-black-orange].

❒24. Install C9, 15 pF.

❒25. Install C11, .001 pF [marked .001,102, or 1 nF].

❒26. Install L3, the slug tuned coil. It is important that the body of this coil be snug against the PC board for mechanical stability, which directly affects the frequency stability of the receiver. Make good, solid solder connections!

❒27. Install C12, 8.2 pF.

❒28. Install varactor diode D1, marked BB505. It is important to orient this part as shown in the parts layout diagram.

❒29. Install R8, 47K ohms [yellow-violet-orange].

❒30. Install R9, 270 ohms [red-violet-brown].

❒31. Install C13, .01 uF (marked .01 or 103 or 10 nF).

C14 is the first of the electrolytic or "polarized" capacitors that you will install. This means these capacitors have a positive (+) and negative (-) side and therefore a right and wrong way to be installed. Ordinarily, only the negative side is marked on the capacitor; a dark band with the (-) sign clearly shown. The value of C14 is not critical and may be any value from 100 to 220uF.

❒32. Install C14, 100 to 220 uF, observing correct polarity.

❒33. Install C15, 4.7 or 10 uF, observing correct polarity.

❒34. Install jumper JMP1.

❒35. Install jumper JMP3.
