[QUOTE="s-band, post: 1064415, member: 407744"] I can't remember if the Tit IF went down to 250MHz without mods, I think I had to do something to extend the LF response. If it does, it would need the filter modifying or removing. If you remove it, as I did, the Tit is on the edge of instability. Once modified as my link, it works OK up to about 4.75GHz. The only lock I managed was an ACM/VCM TP on Rascom 2.9E on a 1.5m dish. I came to the conclusion that it was OK but not really worth the effort. The Norsat full band or your (moonbase) Chinese ones make more sense. If you've got a spec an, check the output of the tit down to 250MHz. to see if there's any noise, I don't think there will be much. Try bypassing the filter, it would be interesting to see if it works without switching the LO as per my mod. If that works and you've got a TBS69x3 you might get something in the extended band. That mixer would work but it's a pain to use without the eval board which is not cheap. A mini-circuits one off Ebay would be easier but you'll need an LO and filters. Once again, easier to use a Norsat or Moonbase's. [/QUOTE]
