With the integration of computers into the hobby and the various software programs available it's inevitable that problems can and will develop. Listed here are a combination of tips and troubleshooting methods that have  been employed at The Monitoring Post.</div> <bR> <bR> <div> <B>Interference to APT Weather Satellite Reception </B>- an article originally published in RIG Journal, No. 51 by Alan Sewards and posted <A HREF="http://www.eumetsat.de/" target="_blank"" TARGET="_top" TITLE="http://www.eumetsat.de/" target="_blank""><U>here</U></A> explains in summary the common types of interference and solutions available.  Once the Eumestat home page is displayed you'll need to click on "<I>Data, Product and Services</I>" to display the sub-menu. Click on "<I>Image Data Dissemination</I>" and at the bottom of this page is a link to the article.

For <U>best results</U>, one should adjust their receiver to tune slightly higher than the transmitted frequency as the satellite approaches and then lower as it moves away. For most receivers this process can be automated quite easily. Users can program the various frequencies at the different increments - usually no more than 5 kHz steps for a 5 kHz receiver. For example, the International Space Station transmits on 145.800 MHz therefore one could program the frequencies 145.805 MHz, 145.800 MHz and 145.795 MHz into their receiver and then either manually tune each frequency as needed or, if computer controlled, the software will tune each frequency as appropriate. You'll need to review the owner's manual for your receiver for specifications and programming instructions. For total automation, <A HREF="software_receiver_control_software.htm" TARGET="_top" TITLE="Software"><U>specialized software programs</U></A> are available that adjust for the Doppler Effect knowing only the frequency the satellite transmits on.</div> <bR> <bR> <bR> </td> </tr></table></body>
