IQPro DDS VFO -  $195  (PC Boards only - $25 + $2.50 s/h,  Pair of pre-programmed PIC’s $25 + $2.50 s/h)

 The IQPro is a DDS VFO designed by AA0ZZ. It was published recently in the May/June 2006 issue of QEX. It is designed to work with any of the KK7B modules. Features include:

• AD9854 DDS with two PIC microcontrollers(16F877’s)
• 0 – 30 MHz continuous tuning
• Dual outputs (I and Q) for SSB Rx and Tx
• 24 pushbuttons and 9 LEDs
• 16 x 2 LCD
• Optical encoder for smooth tuning
• Output signals for separate band specific filter relays
• Entire board runs on 5 volts.  A 12v to 5v switching power supply (about 1” square) is included so a 12v supply can power the IQPro
• All thru-hole parts except AD9854 (which is pre-mounted), 125 MHz clock, and MOSFET

40 pages of documentation are included with the full kit.  The full kit includes:

• all PC boards with the AD9854 pre-mounted on the board
• the DDS board and the PIC board are supplied as one board (3” x 6”) that can be snapped apart if you want to enclose them in separate shielded enclosures.
• PC boards are supplied for push button, led and bandswitch testing
• All on-board parts are supplied
• Optical (not mechanical) Encoder is supplied

Blank PC Boards and preprogrammed PICs can be purchased separately (see top of page). Documentation is not included with the PC boards.  It is available on-line at www.cbjohns.com/aa0zz  along with many more details about the kit. Source Code for the PIC’s is also available at the above web site.
