At the top of the SDRadio and Winrad softwares, there is the "LO IN Frequency" display if you click that then you can enter any L.O. IN frequency you want. When you click this on SDRadio it says "Enter L.O. Frequency" you can enter 0455 Khz or 10.7 MHz or the "L.O. In" of the CIAO H101.
To find the L.O. IN of the H101 receiver just click "Setup" in the Menu Bar and then select "Configuration." in the lower left corner of the task pad window there is the L.O. In Frequency, copy and paste it to the SDRadio or Winrad "L.O. In" feature setup. If you are wanting to listen to WBCQ then the L.O. IN will be 7410000 Hz, just copy and paste this portion " 7410 " KHz to the SDRadio or Winrad. Lastly, if the signal does not correspond to the spectrum display frequency then go to Options and select, "Swap I ~ Q" and then the signal will appear at 7415 on the dial. What the difference in using these softwares? Well, if you have several receivers you know that they can all sound differently and you might want to change the sound to your ears sometime. They have a different tonality to them and this tonality on my PC seems to make them quite sensitive for use on weak signals just as Alberto's website is named www.weaksignals.com. I find the Winrad can pull out weak SSB signals somewhat down in the noise and that I can better hear everyone in the group talking form around the country. So it is good for Amateur Radio work and to pull out those weak shortwave stations running on SSB. How it is doing this for me? I can not say. I am not the software designer. But I am studying about compiling softwares now and maybe one day I'll understand this stuff. The electronics is however is fascinating enough. So far we have seen a few circuits for 455 kHz and 10.7 MHz pass through here and a TM or Time Machine transceiver circuit. Over this winter I think we are going to get more circuit diagrams and then we all might have enough simple circuits to start building and even upscaling. Analog Circuits and Mini Circuits seem promising with their chip ideas. The microwave chip ideas seems also promising for PC controlled HF receivers. Some folk are already into designs for such things. The simple ideas I have found do not go without some complex considerations, just like we had all of the concern over phase noise in VFO ideas earlier here in the group, and they were real issues that had to be looked at. Allot of real issues have to be dealt with even in the minimilist ideas. Passband responce, IMD, phase stability, etc, etc. _____________________________________________________________________ PrivatePhone - FREE telephone number & voicemail.
