	Building the Wavecom JR VFO	By N0QBH

The N0QBH Wavecom VFO module is one of the simplest PIC projects I've
designed.  Since it uses the PIC's on board RC oscillator for it's
clock and it's +5 volts comes from the Wavecom board, I chose to
build it on a generic solder hole perf board instead of the MELabs
PICProto18 board that I usually use.  Both work equally well in this
application.

Here is the parts list:

	1 - PIC16F627 or 16F628A Micro
	1 - 16 Character LCD Display module.
	1 - .1 uF power supply bypass capacitor
	2 - 47k pull up resistors
	2 - SPST switches
	4 - approx 6" 22-24 ga wires for connections to Wavecom

Build the interface according to the schematic.  Note the I2C lines
don't have pull up resistors. Pull up is provided by the Wavecom.
SDA is the I2C serial data line that goes to PIC pin #17 (A:0)
SCL is the I2C serial clock that goes to PIC pin #18 (A:1)

The switches are normally open type. They each do have a pull
up resistor (47k) and are designed to put a logic low on their
respective PIC pins #1 (A:2) and #2 (A:3) when pressed.

I also recommend using an IC socket for the PIC.  That will make it 
easy to reprogram as I (or someone else) come out with improvements
to the original software.
