Insert all the components that have their values inside the footprint. They are the following: ____10 - .01 capacitors (Bag 3), Solder ____4 - 100 ohm resistors (brown, black, brown) (Bag 3) Resistors:____2 - 12K (Bag 4), Above the right side of the MOSFETs. Solder Other Parts:____2 - MOSFETs (Bag 2), (Picture) static sensitive part, touch a ground wire before taking it out of the bag, notice the dot on MOSFET (may be difficult to see, hold at an angle to a light source and you can see the shadow of the dot), the dot is located to the left of the second line of the text on the MOSFET. A dot is placed outside the footprint so that you can double check your placement after it has been soldered to the PCB. The leads on each side of the part need to spread apart slightly to fit the footprint.Solder ____2 - LED (Bag 3), Red colored, match the flat on the LED to the flat on the footprint. Located below the MOSFETs. The short lead is on the same side as the flat. Solder |
Circuit Details - S-Meter
before building this section.
Note: If you are using the Plastic S-Meter (the one listed on the order form), with the 200uA movement, for Mtr1 use a 22K resistor (check S-Meter package for resistor) instead of a 100K as shown on the PCB. That will lower the 100K resistors you will use to 3 instead of 4 as noted below. The Mtr2 value will not change, a 100 ohm resistor will be used as noted on the PCB. If you are using the 50uA S-Meter, use the values as shown on the PCB and follow the instructions below exactly. Insert all the components that have their values inside the footprint. They are the following: ____7 - .01 capacitors (Bag 3) Solder ____3 - 100 ohm resistors (brown, black, brown) (Bag 3) Solder ____4 - 100K resistors (brown, black, yellow) (Bag 3) Remember, if you are using the plastic S-Meter, the 100K resistor at Mtr1 will be 22K in place of the 100K. Solder Resistors:____1 - 12K (Bag 4), Located above the right side of the MOSFET. Solder Capacitors:____1 - 10mfd Tantalum (Bag 4), 3 pin (Bag 4), The center pin is positive, two outer ones are ground, this part is used in automatic insertion PCB work so that it never gets put in wrong, located to the right of the 2N3904 transistor. Solder Other Parts:____1 - LED (Bag 3), Red colored, match the flat on the LED to the flat on the footprint. Located below the MOSFET. The short lead is on the same side as the flat. Solder ____1 - 50A02 455IF can, White core (Bag 5), Located to the left of the MOSFET. After inserting into the board, touch the soldering iron to the IF can pins first, and make sure the pin is accepting solder before flowing solder onto the PCB. Solder |
____Cut one 3" length of hookup wire and connect the AGC Squares (BOLD lined squares) at the first and second amplifier in the IF strip. This can be done underneath the board to provide a cleaner appearance above the board. Picture |
