I've tested it with Guido's direct program. Its ok with that. It even goes to 6m... PowerSDR-SR40 is the trouble. I try to debug it with my VisualStudio2003 and see what is the difference. I guess there are some issues of HS_DIV,N1 and RFREQ and Si570 goes into startup frequency. what puzles me is that the code is exactly the same in both of them... SV1EIA
