Hello Leif, many thanks for your kind replay. With IK7EZN helps, all resolved. I have just renamed both dsp_wcw files with the right name (dsp_wcw_corr and dsp_wcw_iqcorr). Now all work properly with my satisfaction. I guess that this time a simple beer is not enought to pay IK7EZN helps,hi,hi.
ciao Leif and hope to hear you again. Your Linrad is really very appreciated here although i work on linear (H) pol.
