FD-SIGEN-0517

1MHZ to 160MHZ Digital VFO:

THIS PROJECT IS UPDATED AND RE-NAMED AS R1-CPU. PLEASE VISIT R1 HERE......

Si5351 Based 1 to 160MHZ Signal Generator:

SIGEN-0517 is a dual signal generator with following useful features:

1 Si5351 Signal Generator at 25MHZ
2 Two Independent signal generation from 1 to 160MHZ
3 Encoder for tuning, 1HZ to 1MHZ Steps Configurable.
4 Two Button Simple Menu Operation (User + Config)
5 IF OFFSET, Plus or Minus Values 
6 Signal CLK0 is displayed on LCD
7 Second Signal (CLK1) from 1 to 160MHZ for 2nd IF etc.
8 Variable tuning steps from 1HZ to 1MHZ
9 2 X 16 LCD
10 Uses PIC18F25K22 Micro Processor
11 Receiver S Meter Option at PIC PIN2
12 Auto LCD Back Light OFF to save power
13 Internal 3.3V regulator and PCA9306 I2C Chip
14 Small Size: 14CM X 4CM Glass epoxy PCBs
15 Works on 5V DC
16 Option to use SMA Connectors for signal output or direct coax connect
