- I just uploaded to the files section a PICAXE program that based on
pressing keys on a PS/2 keyboard (that is that extra PC keyboard in the
floor of the closet) will control a Si570 in the following way:
Press the 1 key will set the center frequency to 14.02 MHz (56.08 MHz
to the softrock). You use the softrock to look up or down 20 KHz.
Or Press the 2 key for center frequency of 14.06 Mhz. And so on up the
20 meter band.
This is not meant to be the ultimate. It is just to demonstrate what
is possible with very simple hardware and software.
Use your favorite processor.
Use your favorite band.
Use your favorite input device (10 position switch, joy stick, tv
By the way, the group buy interest is up to 81. The next price break

Here's the schematic for an Si570 PCB I'm working on:
The board includes a PIC16LF88 MCU, with a 3.3V LDO regulator, and has
connectors for a rotary encoder and two pushbuttons. It's mostly
surface-mount, and being single-sided will be easy to make at home. Size is
1.325" x 2.15".
Is that a ICSP connector to program the chip? Or is it some other standard.Yes, it's for an ICD 2 debugger/programmer.73, Leon
