Hi Cecil,
I can't seem to get to the link as you have posted in email. I will be using the Si570 LVDS type. It looks like I may need a XTALL board from Tony also, I wonder if he has a board set up for the LVDS Driver F1002 and a regulator. 73, Ray, N0FY SKCC # 3704 "It's not the years in your life that count.

How do you access the 40 frequencies (program, switch etc??)?? Thanks 73, Ray, N0FY I'll let him tell you but the way he did it is very clever considering the limited I/O pins. The circuity is quite simple and is posted on the file section. It uses a 12F683 8 pin PIC, a 4 position DIP switch to set the band and frequency, and several resistors and capacitors. The circuitry is so simple it's not hard to duplicate, the only physically weird chip is the SI570 and even that can be tamed easily, I mounted one on a 8 pin header so I can plug it where I want to. < http://f1.grp. <http://f1.grp.yahoofs.com/v1/sOAXSCuDKjuOhlVmHQcF0bDSsC2q5Q15Hu6Z9IxsbkH2pg eHr04vbnPXYNgvYy2Kgv_GjxdECDffpvJ1iSxVRxpAzbw/Lite+Xtall%20beta%20kit/Lite+X tall%20v8.1/Lite+Xtall%20schematic%20v8.1%203_18_08.pdf> yahoofs.com/v1/sOAXSCuDKjuOhlVmHQcF0bDSsC2q5Q15Hu6Z9IxsbkH2pgeHr04vbnPXYNgvY y2Kgv_GjxdECDffpvJ1iSxVRxpAzbw/Lite%2BXtall%20beta%20kit/Lite%2BXtall%20v8.1 /Lite%2BXtall%20schematic%20v8.1%203_18_08.pdf > Cecil K5NWA There are some references to the software here, and copies of the hex files to use in flashing a blank CPU.. < http://groups. <http://groups.yahoo.com/group/softrock40/files/XTALL%20daughter%20board/> yahoo.com/group/softrock40/files/XTALL%20daughter%20board/ > Cecil K5NWA www.softrockradio. <http://www.softrockradio.org/> org www.qrpradio. <http://www.qrpradio.com/> com "Blessed are the cracked, for they shall let in the light."
