[QUOTE="moonbase, post: 1036377, member: 178786"] gap30, The strongest transponder I get from 40.5W with a 1.5m dish is 3682 L, SR3030. With a Technomate TM-5402 (M3) receiver I get 10.3db / 74% signal level using a Titanium LNB fitted with dielectric plate. As you are using the same size of dish you should be able to lock this signal if your dish alignment is OK. One possible point to note is that the feed opening on the LNB may need to be closer to the dish compared to that of a Ku band LNB. This is the case for a prime focus dish but as I do not use offset dishes I am not up to speed with their focal length adjustments required for different frequency bands. For the 1.5m prime focus dish I use, the Ku band feed is ~4mm inside the focal length of the dish and the C band feed is ~11mm inside the focal length of the dish. Lastly, to increase your chances of finding a C band signal it might be useful to try only for QPSK modulated signals. The 8PSK modulated signals require a higher signal level to achieve a lock on a satellite receiver. Rgds [/QUOTE]
