the counter is based on the AT90S8515 Microcontroller . it can display up to 10GHz in resolution of 100 Hz, (input range is 10MHz to 2.4GHz) or display up to 100 MHz in resolution of 1 Hz , & other modes.... http://elm-chan.org/works/uctr/report.html
I had made one for my old vacuum tube receiver. It uses PIC microcontroller, the highest working frequency is 50MHz, and could be reach 1G by freq devide chip. If anyone needs the total design, please contact me by email or message, I will send the protel design files to you.

Post a picture of schematic here? I think the original design file is better for you all, it include both schematic and pcb. I had already sent to several guys this afternoon.
