Hi John-

Good to hear from you.

Rich, N3III, our chief and primary motivator, has bought a home in northern 
Baltimore county and just moved there last week.  He says he has no 
broadband internet available and no cell phone coverage, but has a good 
route planned on the map to get back to Carroll County.  Hopefully, he will 
be in touch with McHUG soon.

I also wrote a C program, but for the ATmega128, to control the frequency of 
the Si570 digital synthesizer chip.  The frequency is displayed on an 
alpha-numeric 16-character LCD display and push-buttons allow you to 
increment or decrement any digit of the displayed frequency.  Right now, it 
is set up for a development board, but I plan to port the code over to the 
ATmega168 BBB board we assembled at the club.  I ordered components to build 
a box with the controller, display, and synthesizer inside but my order was 
just shipped after over two months of waiting.  The order was from 
www.futurlec.com in Australia that sells mostly with Asian made parts and 
board assemblies.  Prices are good but you have to be patient.  (Steve, 
N3SB, has ordered from them several times.)

I also plan to build the SoftRock Lite/Xtall with the Si570 being controlled 
by an ATmega controller.  Should be interesting.

I need Rich back for inspiration.  Hopefully, he'll be at the club meeting 
on the 14th.

-Pete, W3GVX
