Alberto wil be able to answer some of the technical questions regarding frequency control tomorrow. He has already created DLLs for several receivers. I will answer some of the questions regarding features and directions as it was I who asked Alberto for his assistance and partnership to create winrad. I too have as a focus, EME and weak signal microwave operations where I wanted to display a significant bandwidth. I also helped the project by setting some of the features as goals and prioritizing their development. My intention is to develop transceive hardware in this new year that will work with a special version of winrad.
I have definitely used linrad and have it on two computers here. I understand the need to pass the transmit frequency to the separate transmitter as I have a set of WSE converters. Leif and I are good friends and we assist each other. We agree that the two programs each serve somewhat different needs but do have overlapping applicability. So at times we add similar features to our programs and other times the features won't be duplicated. I have been following the networking capability of linrad and also the combination with WSJT. It is my opinion that these are wonderful features but winrad needs to catch up on certain other ones that are more important. So right now Alberto and I have as a priority, automatic (or at least semi automatic) image rejection. Then we want to implement the calibration and normalizing routines similar to those you already find in linrad. Thus the suggestion for passing spectum data will not be done at this time. I am also working on the difficult (and perhaps impossible) task of de-spreading 10GHz EME signals. Since these are entirely phase incoherent it is difficult to mathematically distinguish this signal from random noise. Serge's program which uses many many averages works quite well but that constrains operation to long sequences of repeated CW sent by a computer and then decoded by another computer. If there is any way, I would like to make it easier for the human CW operator to be able to better hear the EME signals in near real time and decode by ear. It will never be able to allow us to decode CW that is 30dB below the noise floor which Serge's program can do. 73, Jeffrey Pawlan WA6KBL _______________________________________________ Winrad mailing list [email protected] http://winrad.org/mailman/listinfo/winrad_winrad.org
