INSTRUCTIONS FOR BUILDING THE SWR-Kit, A component of the multiPIG+
updated 05/28/03 8:00 AM

The SWR kit includes the following:
  1. XMTR PCB
  2. Plastic bag with parts
  3. wire
  4. Schematic

We will build the SWR in this order:
  0. Review instructions. Inspect PCB and parts.
  1. Install resistors and Diodes
  2. Install headers
  3. Install ICs and displays
  4. Install capacitors
  5. Install all Pots.
  6. Wind and install all toroids.


Ready...set...begin!

INVENTORY all the parts against the parts list.



NOTE: R11 and R14 are not used.
R15 and R16 are wire shunts.
All resistors are 1/8W except R5 and R6
